Welding method with acetylene, oxygen, water gas as heat source, such as, the two edge forming of tube billet heating, make the weld filler, composite steel pipe welding.Welding and brazing welding points.
Welding is by using a mixture of oxygen and acetylene gas combustion, and a significant amount of heat will be welded joint of metal and filler metal (electrode) melt (or no filler metal) as a whole to become solid weld, call it welding.Brazing is the use of the solder melting point lower than the parent metal heating with the parent metal.Solder melted under the effect of capillary wettability and populate the junction surface, solder and parent metal dissolve each other and spread, the obtained solid solder.Can produce double layer or multilayer brazing welding tube, double metal and spiral tube.
Welding method, besides can be welded steel pipe, as long as choosing the appropriate welding rod and welding flux, also can welding alloy steel, copper, aluminum and other non-ferrous metal tubes and metal tubes.Welding flux can avoid the high temperature of metal with oxygen to form oxides and eliminate the metal oxides.
