When a long, successive weld is needed then seam welding is the way to go. Seam welding forms a weld progressively as it moves from one end to the other and the weld is created continuously.

Seam welding is often used on steel tubing, and is ideal for when a seamless weld is called for.



Why do we need Seam welders?

Seam welders create very strong and durable welds, which look even due to the seam welder moving at a regular pace. It’s usually automatic, which allows for that more even weld.

This even weld makes the finished weld look much cleaner, therefore increasing the overall appearance of the object. This is ideal for when the weld is going to be plainly visible.

Types of seam welder you would use, depending on your job, are longitudinal and circumferential and are used alongside either a MIG, TIG or plasma welding power source, depending on the welding process of choice.

Seam welders are used to manufacture cylindrical items such as exhausts, flues and vents.

In stock are a variety of longitudinal and circumferential seam welding machines with varying clamping lengths and diameter ranges.

Seam Welders are supplied to a weld a wide variety of applications including MIG/MAG, TIG, Sub-Arc and Plasma Welding in an external seam.

We buy and sell brands we trust to perform. ProArc have supplied our our range of new seamers for over 15 years. Other tops brands include Jetline, Bode, Gullco, Sciaky, & Bug-o

Westermans can supply the Seam welding machine alone or offer a bespoke solution with any choice of welding application that the customer requests or the job requires.

The advantage of using a Seam Welder easily enables the joining of two flat plates or the longitudinal seam of a tubular pipe without tack welding. A Longitudinal Seam Welder gives the welding operator repeatability at the touch of a button as the welding carriage travels down the length of the work piece. A Seam Welder can be used to weld either internally or externally.

The Seam Welder is ideal for use in a production line were the quality of weld and finish is essential. Seamers can be found in a variety of applications from shipbuilding, copper cylinders, boilers, and tanks to stainless steel household bins.

Resistance seam welding, Butt welding and Spot welding can also be known as seam welding. Seam welding is a process of welding a lengthwise seam in sheet metal either by abutting or overlapping joints. Seam welding is commonly used during the manufacturing of round or rectangular steel tubing.
