@.tech.daily: A linear welder is a type of resistance welding machine that joins two pieces of metal along a straight line (linear seam) rather than at a single point. Here’s how it works: It uses opposed electrodes, usually in the form of wheels or bars, that apply pressure and pass an electrical current through the workpieces. As the material is moved under the electrodes, a continuous or overlapping series of weld nuggets is formed, creating a sealed seam. This process is often called seam welding or linear resistance welding. Video credit: muffler by plomp
