Electric resistance welded (ERW) pipe is manufactured by cold-forming a sheet of steel into a cylindrical shape. Current is then passed between the two edges of the steel to heat the steel to a point at which the edges are forced together to form a bond without the use of welding filler material.
A welded stainless steel tube is produced through roll-forming strips or sheets of stainless steel into a tube shape and then welding the seam longitudinally. Welded tubing can be accomplished either by hot forming and cold forming processes. Of the two, cold forming results in smoother finishes and tighter tolerances.
Pipe welding is a fundamental process in joining metallic pipes to create a continuous and sturdy connection. It plays a pivotal role in various industries such as construction, manufacturing, oil and gas, plumbing, and more.
Choose a machine that accommodates the size and material of your square tubes. Check its capacity for both maximum and minimum tube dimensions and ensure compatibility with materials like stainless steel, aluminum, brass, and others.
Stainless steel can be stick welded, shielded metal arc welded (MIG), or gas tungsten arc welded (TIG). The best choice depends on what you’re trying to accomplish since each process yields a different outcome.
