Spot welding (or resistance spot welding[1]) is a type of electric resistance welding used to weld various sheet metal products, through a process in which contacting metal surface points are joined by the heat obtained from resistance to electric current.
The process uses two shaped copper alloy electrodes to concentrate welding current into a small "spot" and to simultaneously clamp the sheets together. Work-pieces are held together under pressure exerted by electrodes.
Seam welding is a welding technique in which two similar or dissimilar metals are connected by supplying an electric current and in this process a nugget formation takes place. Mostly, these nuggets are formed in the form of a butt or overlapping welding components. Do you know the meaning of these nuggets? Well, the nuggets are nothing but small pools of molten metal which are formed at the location with high electrical resistance. Seam welding is one of the types of Resistance welding.

Well, the nuggets are nothing but small pools of molten metal which are formed at the location with high resistance. Spot welding and seam welding are two of the most commonly used welding processes in the manufacturing industry. Spot welding is a process that uses heat and pressure to join two metal pieces together. It applies an electric current between two electrodes, creating an electrical arc that melts the metal at the point of contact. Seam welding is a similar process. But instead of using two electrodes, it involves running a continuous wire along the seam of two metal pieces to join them together. Both are used in automotive and aerospace manufacturing for joining sheet metal components.Spot welding is better utilized for welding materials that’re smaller and are overlapping. Spot welding has a manual mode while seam welding does not. Seam welding is great for welds that need an air-tight seal (remember that spot welds tend to not be the best overall. It’s also great for welds that must be continually done such as for placing strings of spot welds.What are the best uses for spot vs. seam welding? Spot welding is ideal for joining thin sheets of metal. Making it ideal for light duty applications including electronics and battery manufacturing. It is also widely used in the automotive sector, due to it’s ease of automation in high-volume production lines.
While seam welding is best suited for joining.thicker materials, or creating a continuous weld along a seam. Thus making it ideal for the fabrication of tanks and vessels, as well other pipe and tube welding applications.Spot and seam welding are both important methods in many industries today. Spot welders are ideal for projects re
