Acetylene gas had been discovered much earlier in England when Edmund Davy in England found that a flammable gas was produced when carbide was decomposed in water. In such cases, gas welding is often preferable, bearing in mind the less bulky protective equipment required (goggles, as against a normal arc welding helmet or visor, and compact torch) to perform the work. High energy beam welding: This makes use of a united energy beam with a high power to liquefy the metals previously welding. The Arcos Corporation introduced another vertical welding method, called Electrogas, in 1961. The alternative to gouging for this task is mechanical chipping, which is slow and arduous. Dog Welding Dog Bracke. Then, the parts are usually tack welded using a tacking tip (Fig. prostockstudio.
