What is Resistance Seam Welding? Process and Uses

Resistance Seam Welding

Resistance seam welding is an automated process that uses electrical resistance to join two pieces of metal. It can be used for various automotive, shipbuilding, and aerospace applications. This article will look at what it is, how it works, and its many uses.

What is Resistance Seam Welding?

Resistance seam welding is a beneficial process for joining two or more metal sheets. This process allows welders to efficiently join multiple pieces of sheet metal without adding filler material. This is especially beneficial in operation areas where gas welding is not suitable or feasible due to joint distance and the size of the materials. As a precise, continuous and clean process, resistance seam welding offers many advantages for use on diverse materials such as aluminium, copper and stainless steel. Due to its short cycle times, high-quality bonds and easy automation capabilities, resistance seam welding has become one of the most popular techniques for welding automotive parts and aerospace components in factories worldwide.

Resistance Seam Welding Process

The process of resistance seam welding involves using two electrodes pressed against the two pieces of metal to be joined. These electrodes then generate heat through electrical resistance as current passes between them. This heat melts both metals and creates a fusion bond between them when cooled. The pressure the electrodes apply helps ensure that the welded area is free from voids or gaps. Different temperatures and pressures may be used depending on the material being welded and the desired strength of the weld.

Resistance Seam WeldingUses

Resistance seam welding has a wide range of applications. It’s often used in automotive assembly lines due to its ability to produce strong welds quickly and consistently. It’s also commonly used in shipbuilding for creating large-scale steel structures such as hulls or decks. Additionally, it’s also extensively used in aerospace applications due to its ability to create strong bonds on thin materials such as aluminum or titanium sheets that are otherwise difficult to weld using other methods.


Overall, resistance seam welding is an incredibly versatile process used in many industries for various applications. Its ability to create strong, reliable welds with minimal preparation makes it ideal for many production lines requiring quick turnarounds. By understanding how this type of welding works and what materials it can work with, you can determine if it’s right for your project and start taking advantage of all its benefits!
