In seam welding, overlapping sheets are gripped between two wheels or roller disc electrodes, and current is passed to obtain either the continuous seam i.e., overlapping weld nuggets, or intermittent seam, i.e., weld nuggets are equally spaced. Welding current may be continuous or in pulses.

Continuous spot-welding process:
Seam welding is a continuous spot-welding process where two overlapping pieces of metal are welded together along the length of the seam. It is commonly used in the automotive industry for welding components of vehicle bodies, such as panels and frames.
Process:
- In seam welding, an electrode wheel rotates and applies pressure to the overlapping metal pieces while passing a current through them.
- The current generates heat, which melts the metal at the seam, creating a weld.
- The rotating electrode wheel moves along the seam, creating a continuous weld.
Advantages:
- Seam welding produces a strong and leak-proof weld along the entire seam.
- It is a fast and efficient process, making it suitable for mass production.
Applications:
- Seam welding is commonly used for welding cylindrical objects like pipes and tanks, as well as flat sheets of metal.
- It is also used for creating mesh structures by welding wires together.
In conclusion, seam welding is a continuous spot-welding process that is used to create strong and leak-proof welds along the length of a seam. It is a versatile welding technique that finds applications in various industries, including automotive and manufacturing.
