gas welding
Quick Summary
Gas welding is a fusion welding technique that uses heat generated from a gas flame to join metallic parts. This method was developed at the end of the 19th century as part of advancements in welding technologies, alongside arc and resistance welding. While once a primary industrial process, its use has become more specialized, often employed in sheet fabrication and by artists. The process involves burning acetylene in oxygen to create a controlled flame, with a cold filler wire added to the joint. Fluxes are typically used to prevent oxidation and ensure a strong bond.12
