Welding is an ancient art dating back to the Bronze Age. It produces a stable and inherently strong bond that can’t be matched by any other methods. Welding is the process of fusing two materials together using extrerme heat pressure and/or fillers. Welding processes have developed to fit every industrial need imaginable.

For our purposes the types of welds used are:

Spot Welding
Spot welding is a type of resistance welding used to weld various sheet metals. The process uses two shaped copper alloy electrodes to concentrate welding current and force between the materials to be welded. The result is a small “spot” that is quickly heated to the melting point and forms a nugget of welded metals after the current is removed. Current and duration are determined by the materials and their respective sheet thicknesses and type of electrodes.

Standing Seam
Like spot welding, seam welding relies on two electrodes to apply pressure and current to join metal sheets. However, instead of pointed electrodes, wheel-shaped electrodes roll along and often feed the work piece, making it possible for long continuous welds.

Continuous Weld
A weld that is continuous along the entire length of the joint.
