Welding Applications

Resistance Welding Equipment Helps Industries Save Costs, Increase Structural Stability and Provide Reliable, Repeatable Results.

Automated Butt Weld Wheel Rim Line


Resistance welding in the automotive industry is probably the most common. During vehicle assembly, there are three resistance welding processes that are typically leveraged: spot welding, projection welding (a variation of spot welding) and seam welding (a variation of spot welding).

Projection Welding in the automotive industry is commonly utilized for the fastening of screw machine parts to metal, including studs and nuts as well as brackets and parts of dissimilar gauge thickness.  It is also used to join wires and bars that must be crossed.

Resistance spot welding is particularly advantageous in the automotive industry due to its ability to provide rapid, high volume manufacturing, operational ease, safety, low environmental impact, cost efficiency, as well as stable, repeatable results.

Resistance seam welding is commonly utilized as part of the automotive system where parts require liquid-tight or water-tight construction such as exhaust systems or fuel tanks.

Flash or Butt welding is common for joining parts where the entire cross section is joined together such as axle assemblies, linkage assemblies, torque rods and most notably, wheel rim products.

Fusion Welding such as MIG/TIG welding machines or Laser welding cells are usually for attaching heavier thickness of component parts together or where full or a majority of the periphery of the joining parts need to be joined together.

Welding: Aerospace Industry

Resistance welding in the aerospace industry is utilized to join parts made of certain metals that possess high strength, yet lightweight properties. Common alloys include Titanium and Inconel, Aluminum and other Nickel-based alloys, etc.

Like the automotive industry, the aerospace industry also utilizes spot welding, projection welding, seam welding and flash welding in very critical production jobs

Resistance Flash Welder

Welding: Railway Industry

Resistance welding in the railway industry is particularly advantageous due to its ability to provide high structural integrity, aesthetic qualities and high productivity.

Resistance welding is used throughout the process of railway car fabrication. It is also used for joining railway rails, as well as joining different materials in railway switches.
