What is the Process of Seam Welding?

A seam is a point where two ends of a single vessel are joined together in order to give it a cylindrical or circular shape. Seam welding is most commonly used for the production of tanks, cylinders, drums, etc.

Metals varying in thickness from 0.1 mm to 10 mm are joined in a straight line using seam welding. In most seam welding processes, water cooling is mandatory in order to ensure that there is no damage caused to the welding material.

There is no thermal distortion to the welding material in seam welding and it delivers 100 percent penetration in a single pass weld on untacked cylinders and flat sheets without the need for tacking. This optimizes any welding process by lowering welding costs while also improving the quality of the weld.

What is the Difference Between a Longitudinal Seam Welding Machine and a Circumferential Seam Welding Machine?

A circumferential seam welding machine is a device that may assist you in joining two circular items together. Instead of welding them together at the ends, you may weld them together around their circumferences.

Whereas, a Longitudinal Seam Welding Machine would only weld a single workpiece and join its two ends together.

You can use a Longitudinal Seam Welding Machine for nearly all kinds of materials, however, there are definitely certain materials that are ideally used for an effective outcome.

These ideal materials would include carbon steel, stainless steel, aluminum as well as titanium alloys, and copper alloys.

You can use a Longitudinal Seam Welding Machine for the purpose of joining the inner and outer longitudinal seams of cylinders together.

These cylinders usually have a medium-thin wall thickness of around 0.5-6 mm. A Longitudinal Seam Welding Machine can weld at the speed of 150-1500 mm/min depending on the material and the kind of machine you use.

It also offers you features such as a pneumatic lifting mechanism and a two-dimensional manual adjustment mechanism. Using a Longitudinal Seam Welding Machine, you can perform straight welds for components that are bent into cylindrical, conical, and rectangular shapes as well as sheet metals in the form of plates.

Instead of using rods to weld, Longitudinal Seam Welding Machine makes use of motor wheels to proceed with the welding process. In order to fulfill the welding requirements, you can adjust the welding torch in multiple directions such as up and down, left and right, forward and backward, as well as adjust it according to a specific angle.

DC motor drive: It is used for speed regulation and a rapid welding process along with saving up on energy.

Clamping units: In these seam welders, there are specific clamping devices for untacked joints that are available and are responsible for holding the welding material at a certain angle while it moves forward. The tack ensures precise carriage motion via the use of precision torch movement and a machined beam, among other features.

Heat sink: Heat sinks are used in a Longitudinal Seam Welding Machine for the removal of excess heat so that the welding material does not melt and water cooling is also used to avoid damage to the workpiece.

Drag chain: A drag chain is used for the purpose of carrying the workpiece as well as transporting it further as the seam weld proceeds. Other components included in a Longitudinal Seam Welding Machine include a support mandrel, a copper welding pad, and copper keypress fingers.
