【Summary Description】 1. Gas welding: The use of oxygen acetylene or other gas flame heating base metal and filler metal, to achieve the purpose of welding. The flame temperature is about 3000°C. Suitable for thinner workpieces, small diameter pipes, non-ferrous cast iron and brazing. 2. Manual arc welding: Using the arc as a heat source to melt the welding rod and the base metal to form a weld by manual welding method, the arc temperature is about 6000-8000 ℃. Suitable for ferrous metal and some non-ferrous metal welding, a wide range of applications, especially for short welds, irregular welds. 3. Submerged arc welding: (Sub-automatic and semi-brake) The arc burns under the flux area, and granular flux is used as the covering layer of the metal molten pool to isolate the air so that it cannot enter the molten pool. The welding wire is continuously fed into the arc zone by the wire feeding mechanism, and the welding direction and moving speed of the arc are completed manually or mechanically. It is suitable for welding straight welds and regular welds of carbon steel, low alloy steel, stainless steel and copper of medium and heavy plate materials. 4. Gas welding: (Gas Shielded Welding) Arc welding in which a welding zone is protected by a shielding gas. The protective gas acts as a protective layer for the metal bath to isolate the air. The gases used are inert gases, reducing gases, oxidizing gases for carbon steel, alloy steel, copper, aluminum and other non-ferrous metals and their alloys welding. Oxidizing gases for carbon steel and alloy steel alloys 5. Ion arc welding: The use of gas in the arc ionization, and then through the thermal contraction effect, mechanical contraction effect, magnetic contraction effect produced by an ultra-high temperature heat source for welding, the temperature can reach about 20000 ℃.
