Seam welding is a continuous type of welding process to weld different materials.The weld may consist of a single weld or a series of overlapping spot welds. Seam welding is useful for the production of long lengths of tubes and very precise welds.

Based on technology, seam welders come in different types. Some of the common seam welders are resistance seam welders, arc seam welders, laser seam welders, longitudinal seam welders and circumferential seam welders. Seam welders are also available in different modes such as fully automatic, semi automatic and manually operated.

Some important parameters you must consider before you buy seam welding equipment are:

1. Size of the weld for which you require the seam welders
2. Required strength of the welds
3. The length of the weld
