H Beam Assembly Machine: The Ultimate FAQ Guide

The H beam is one of the most fundamental members in the field of structural steel construction. So, it is crucial to maintain different critical factors in the production line of H Beam. You can assemble the H beam with assembly machines to efficiently perform these vital tasks.

Go through this FAQ guide to answer all your basic queries regarding the H beam assembly machine.

What Is The H Beam Assembly Machine?

The H beam assembly machine is used to assemble the components of the structural H beam before joining them.

The H-shaped beam has three main components. First, using the beam assembly machine, you can position them accurately before joining. Second, once the positioning is complete, you can hold the workpieces with a rigid clamping force.

The assembly machine will also roll the components forward for you while simultaneously keeping the components fixed on position.

What Is An H Beam?

The H beam is a structural component widely used in the field of steel construction. The cross-section of the structure is similar to the shape of the English letter ‘H’. So, the beam is termed an H-beam.

H-Beam

You will commonly see this structural steel construction in buildings used as load-bearing members to support the structure. In addition, they are used as columns to provide vertical support along the cross-section and used as beams to provide vertical support along the longitudinal direction.

Apart from these, there are so many applications of the H beam in different kinds of fields like railway track, construction of large trailers, platforms, bridges, ship and dock building, truss members, support framework, etc.

Another important term, as you may often hear, is the ‘W Beam.’ The W beam and the H beam are identical. The W of the term comes from ‘Wide’ since the flanges of the beam are wider and called a Wide-flange beam.

Do I Need To Use An Overhead Crane To Handle The Materials Before Placing Them On The Assembly Machine?

Yes, you need an overhead crane to handle your workpieces before placing them on the H beam assembly machine.

Overhead Crane Used In Supporting Material Handling

The H beam assembly machine is designed to position components on locations where they are targeted to be joined according to the final design. But to place the components on the input source, you have to place the components on the feeder rolls.

That means the H beam welding machine will carry on the task for you once you have placed it on the feeder rolls. Before that, you have to place them on the feeder rolls.

Since the structural components of the H beam are extensively heavy, so it’s better that you use an overhead crane to handle these components with safety and efficiency. Using the overhead crane, first, you have to place the bottom flange of the H piece in a horizontal positional on the platform.

Next, use the overhead crane to place the central web piece in a vertical position. Finally, you can place the top flange section horizontally on the web section. You mustn’t place the three components using the overhead crane in a single step.

You have to place them as described in three individual steps to efficiently hand over the assembling part on the assembly machine.

How Do I Operate With The H Beam Assembly Machine?

Operating the H beam welding machine is very simple, but you have to follow the steps sequentially to manage an efficient production line of H beams.

There are five main components of the H beam assembly machine that will handle your workpieces to make them ready for the welding operation. These principal components are the main machine, a centering trolley system, an input feeder roller, an output extraction roller, and a control system.

• Use the overhead crane to place the structural parts of the workpiece on the feeder rolls.
• From this step, you can use the control panel to operate all the functions.
• Start the driven feeder rolls to roll and bring the front end of the workpiece just inside the main machine.
• The main machine has several parts. You have to make use of all these components simultaneously to perform a single function.
• The rectangular frame holds the lifting and lowering beam with the two vertical guard rails. You can lift and down the beam that slides on these guard rails.
• A pressing cylinder is attached at the center of the lifting and lowering beam that connects to the top, horizontal member. You have to operate this pressing cylinder to smoothly shift down or lift up the beam.
• The bottom horizontal flange section is fed into the main machine when you roll the driven motor of the feeder rolls.
• The bottom wheels support this flange on the base of the main machine to continue rolling the workpieces.
• Some wheels act as the web centering mechanism attached to the wall plates of the base. This will push the web piece to forcibly position it with perfect alignment at the center of the flange and rotate on your operation to roll the workpiece forward.
• The pressing cylinder will push the web piece vertically downwards against the flange section. Using your controller, shift down or lift up the lifting and lowering beam to provide sufficient force.
• All the three sets of wheels on the base plate, on the wall of the base, and from the top will be rotated in a synchronized motion, followed by your command to move all the workpiece components forward with the same motion.
• Set the speed with which you want to move the workpiece forward synchronized with the welding operation.
• Finally, control the driven motor of the extraction roller to roll the workpiece forward, bringing it out from the main machine.

There might be differences in operating the assembly machines made by different manufacturers, but the general procedures will follow similar steps with minor changes.

What Kinds Of H Beams Can I assemble Using The H Beam Assembly Machine?

With the H beam assembly machine, you can handle and assemble the components of the H beam in position so that you can perform the welding operation to join them. You can use the H beam assembly machine to handle different kinds of beams. The common ones are:

• Symmetrical H beam: The symmetrical H beam has two equal flange members linked by a single web member at the center of each flange member.

For assembling this type of workpiece with the assembly machine, assemble and weld the web section with one flange section. After completion, rotate the workpiece and join the other flange section in a similar pattern.

A Symmetrical H-Beam

• Dissymetrical H beam: The dissymmetrical H beam has two unequal flange sections linked by a web section at the center of each flange.

For assembling this type of workpiece using the H beam assembly machine, follow the same procedure as with the symmetrical H beam, but continue with the shorter flange at the second step.

• I beam: The I beam is of similar shape to the H beam, but the width of the flanges is shorter. To assemble this type of workpiece using the H beam, follow the same procedure as with the symmetrical H beam but with shorter flange sections.

I-Beam

• T beam: The T beam has two components, one flange section and a web section connected at the center of the flange section. To assemble this type of unit, only follow the first step as you proceed with the symmetrical H beam assembly.

T-Beam

• Eccentricity H beam: This type of member is designed by placing the web section not at the center but nearer to the edge of the flange sections to carry eccentric loading.

To assemble this type of unit, you have to manually change the setting through the control panel in the main assembly machine. Then, the machine will shift the position of the web section by the vertical wheels on the base wall to join them.

• Variable Cross section: For the variable cross-section beam, you have to cut your component sections according to the target and place them. Use the control panel to select advanced functions to assemble and position the components according to design as the workpiece is rolled forward.

How Can I Assemble An I Beam Using The H Beam Assembly Machine?

Yes, you can use the same H beam assembly machine to assemble both the H beam and I beam. The assembling procedure for the H beam and the I beam is similar, but the component selection is different.

H-Beam And I-Beam

So, before jumping on assembling, you must first understand the differences between their structural components to easily identify the differences in their assembly procedure.

• Both the H beam and the I beam look similar, but there are characteristic and structural differences between the H and I beam, which greatly matter in the construction field.
• Both of them beams have three components, composed of two flanges and a single web piece in the center.
• The difference lies in the size ratios between the web and flange. In the I beam, the cross-sectional width of the flange sections is narrower. The length of the cross-section for the centrally positioned web part is comparatively larger.
• On the other hand, in the H beam, the width of the two flange sections is wider than that in the I beam. The length of the cross-section for the centrally positioned web part is comparatively shorter.
• The ratios between the flange and web sections for the H beam are higher than the I beam. Moreover, the H beams also have a stronger strength-to-weight ratio, enabling them to carry more force.
• Now focus on assembling. You first have to prepare the components of the I beam, which will be of a different size than that of H beams. Then, place them on the assembly machine using the overhead crane.
• Now, since the flange sections of the I beam are narrower, you have to set the positioning roller of the assembly machine narrower to fit the positioning according to the shape.
• Set the alignment fitting with the longer cross-sections of the web.

The next procedures are the same as you handle the H beam, and you can rely on the assembly machine to handle the rest.

How Does The H Beam Assembly Machine Benefit Over The Traditional Method Of H Beam Production?

The advancement in machines has vastly changed how you can view the production line of H beams in the modern manufacturing world. Here are some key comparison facts analyzed for you to justify how the H beam assembly machine can help you over the traditional systems.

• In the traditional system, the overhead crane was used to handle all the components manually to assemble the workpieces.

With the H beam assembly machine, the overhead crane is used only to place the workpieces on the feeder roller. The machine handles the rest to roll forward, which greatly saves your time.

• The alignment of the web piece over the flange section was manually set, and stationary vertical support was induced in the traditional method. With the H beam assembly machine, all these are done by a wheel-based rolling mechanism.
• In the traditional method, the components were aligned and kept in a stationary position. The welding operation was performed by manual or automatic labor by shifting the position of the weld gun, which was a complicated task.

With the H beam assembly machine, you can keep the welding machine fixed in position and roll the workpieces forward and backward, which is more practical and economical than before.

• There were often chances of error in the alignment of the web piece exactly to the center of the flange sections all throughout the longitudinal direction.

But with the h beam assembly machine, the complete workpiece goes through a single center wheel, for why it maintains a perfect alignment throughout the longitudinal direction.

• In the traditional method, most of the workpiece movement was done manually, which required more labor force. Implementing the H beam assembly machine removes this effort by automatically handling the workpiece and reducing the necessity of labor.

Can I Assemble The Beam With Both A Thin And Thick Cross-sectional Flange And Web Using The Same Assembly Machine?

If you use the h beam assembly machine, you can notice that the web section is handled by the vertical wheelsets coming from the two sides of the main machine. The wheelsets are attached to the wall of the base.

There is a gap between the wheels coming from the opposite directions that fit with the thickness of the web section. If you want to assemble a web piece with more or less thickness, you have to use the control system to adjust the two sets of wheels.

Shift them towards or away from each other to fit them until you have adjusted according to the thickness of the centering web section.

Now for flange sections, the vertical support from the bottom is automatically provided from the bottom wheels. The top support is provided from the wheels on the lowering and lifting beam of the main machine.

This is automatically adjusted according to the height of the web, combined with the thickness of the flange. So, you don’t have to manually adjust anything for working on thick or thin flange sections.

Why Do The Welders Face Stress Complication That Welders Face In The Production Line Of H Beams?

Most of the time, arc welding is utilized in welding and joining H beams. But due to some microlevel reactions, internal stress occurs in the newly welded sections, which is a common problem that welders face in the production line of H beams.

This scenario occurs due to the change in material characteristics of the filler and the base metals. The filler metal is a high-yield-strength metal that gets molten at the welding arc point. Simultaneously, the base metal also melts together to form a joint.

Internal Stress Effect After Welding

When both of these melt, they are expanded. But when they solidify, they quickly contact again. But bow, since the base metal is low-yield-strength compared to the filler material, they cannot contract at the same levels as the filler metal.

Due to the difference in materials compaction rate, internal stress is developed at the micro-level, which weakens the connection.

What Can I Do To Avoid The Internal Stress While Manufacturing The H Beam?

To solve the internal stress problem, you can either refine the welding procedure or control the temperature. Welders implement different practical steps to avoid internal stresses. You can follow these footsteps:

• Refine the selection of electrode
• Choose different types of welding
• Pre-bending or pre-setting the workpiece
• Change the orientation of the weld
• Balance the weld with single or double-sided welds
• Fit-up with a small root
• Pre-heat the workpieces
• Maintain temperature between weld passes

You can implement one or multiple steps to solve the internal stress problem, depending on the situation.

How Can I Automate The Manufacturing Process Using The H Beam Welding Machine?

You can automate the manufacturing process of the H beam by integrating the H beam assembly machine with other supporting components.

You can integrate the H beam welding machine with the assembly machine and the flange and web straightening workstation. You can control all these components through a central command system.

H-Beam Manufacturing

The flange and web straightening machine will straighten the workpieces. The assembly machine will hold the components in place, and the welding machine will automatically perform continuous or distant welding.

To achieve this complete automation, it’s better that you order together with all these components with a synchronized command system from the manufacturing company.

How Does The H Beam Assembly Machine Handle The Workpiece, Ensuring Its Safety?

The H beam assembly machine supports and guides the workpiece with the wheel system made from 40Cr alloy structure steel.

All the different wheel types, including the pressing wheel, web wheel, guide wheel, and main drive wheel, are manufactured from this material, which is excellent in pressure resistance and abrasion resistance. So, the safety of the workpiece is ensured.

Supporting Wheels In The H-Beam Assembly Machine

Can I Assemble The Beam With A Smaller To Larger Flange Width And Web Using The Same Assembly Machine?

Yes, you can assemble workpieces with variable width of flange and web section. The supporting and guiding wheels are not static, and you can move them forward and backward.

Using the control system, adjust the support and guiding wheels towards or away from each other to fit according to the width of the flange and web sections before starting assembly.

How Do I Select A Reliable Manufacturer Of The H Beam Welding Assembly Machine?

Always look for these characteristics in a manufacturer to ensure their reliability. A reliable manufacturer will always:

• Surpass product quality more than specifications
• Target for excellence
• Maintain healthy coordination with clients
• Exhibit proficiency and capability
• Uphold progressive attitude
• Keep up-to-date with modern progression
• Ensure service at short notice
• Set clear after-sales-policy

How Are The Web And Flange Pieces Perfectly Aligned With The H Beam Assembling Machine?

The web and the flange pieces are perfectly aligned using the web centering sensor and mechanism. The sensor detects the total width of the flange and calculates the midpoint where the web should be attached.

Next, the two vertical support rollers are controlled through central command to push and guide the web member from two sides. The guiding perfectly and accurately positions the web on the center to align with the flange sections.

Hydraulic Motor And Gear System Used For High Precision Web Centering Mechanism

What Are The Additional Pieces Of Equipment Involved In The Production Of H Beam Together With The Assembly Machine?

The pieces of equipment involved in the production line of H beam are:

• CNC Gas/Plasma cutting: Use this component to cut the individual workpieces.
• H-beam assembly machine: This unit will assist you in assembling and handle the beam components.
• H-beam welding machine: Use this unit to weld the beam components while the assembly machine holds them.
• H-beam flange straightening: Straighten the flange sections using this unit.

Do I Need To Straighten The Web And Flange Pieces Before Placing Them On The H Beam Assembly Machine?

Yes, it is crucial that you straighten the web and flange the beam members before placing them on the assembly machine.

If you don’t straighten them earlier, there will be the tendency of metal deformation even after welding is completed, which will give rise to internal stress.

So, use the flange straightener machine to first straighten the components before assembling them into final positions.

Can I Get An H Beam Assembly Machine With Multiple Working Zones?

Yes, the manufacturers can produce the H beam assembly machines with multiple working zones to speed up your production line at significant levels.

Multiple Work Zone Setup

How does The Assembly Machine control the Input And Output Of The H Beam?

There are two sets of conveyor rolls system on the two sides of the main machine. One of the conveyor rolls set acts as the feeder rolls to advance the workpieces inside the framework of the main machine.

The other set of conveyor rolls are on the opposite side of the main machine, which you can control to bring out the workpieces.

Does The H Beam Assembly Machine Come With A Variable Speed Control Feature?

Yes, with the control system, you can easily set the variable speed according to the requirement of the welding procedure. This is especially useful when you are working with an automated welding process, and the speed is synchronized with the welding robot.
