One of the most widely used welding techniques for creating an airtight and watertight seal is seam welding.  The seam welding process can be done using GMAW, GTAW or Resistance Welding.  Today we’re going to be sharing some basic information about this high-quality welding option as well as insights about how automation can improve your team’s seam welding process—let’s dive into it!

 

What is Seam Welding?

The process of joining workpieces made of similar or dissimilar materials along a continuous seam is known as seam welding. One of the biggest benefits to seam welding is that the materials can be similar or dissimilar. Seam welding comes in three forms:

  • Traditional Seam Welding: Overlapping weld nuggets using GTAW or GMAW process.
  • Friction Seam Welding: A continuous weld is completed with heat generated by creating friction rather than with electrodes.
  • Resistance Seam Welding: Resistance seam welding is a technique in which the welding electrodes are motor-driven wheels.

Applications for Seam Welding

Within the world of welding, seam welding is one of the most preferred ways of using a continuous weld to join two different pieces of metal. Seam welding offers minimal distortion of heat and results in airtight and watertight seals with no gas formation. Because of these benefits (and more), seam welding has many common applications:

  • Barrel and exhaust systems
  • Pressure vessels
  • Steel drums
  • Radiators
  • Vehicle fuel tanks
  • Refrigerators
  • Oil transformers
  • Much more!

As if that weren’t already enough, there are even more production benefits to an automated seam welding process. An arc seam welding machine can be used for the mainstream manufacturing process, as it can produce high-quality welded seams with 100 percent penetration.

Benefits of Automated Seam Welding

If you are looking for a consistent, high-quality seam weld that can increase your production speed without adding to your workforce, you will want to consider linear seam welders. The design of these automatic welder machines allows the weld seam to be clamped firmly between copper fingers and a copper backing bar. Some benefits you can expect from automating your seam welding include:

  • More efficient loading and unloading of seam welded parts
  • Ideal for a single pass, full penetration weld in cylinders, cones, boxes, and flat sheets
  • Simplifies the switch between seam welding different size parts
  • Our Seam welders can be equipped with TIG, Plasma, Submerged Arc, or MIG welding processes
  • All clamping fingers are equipped with reversible copper tips for maximum life.
