Bury arc the characteristic of automatic solder and application

Bury arc the advantage of automatic solder is: (1) manufacturing efficiency is tall. Bury arc the productivity of automatic solder can raise 5 ～ than manual solder 10 times. Because bury,arc does not have coating on the welding wire when automatic solder, welding wire but very long, can send continuously need not change then welding rod. Reason can use big electric current to solder (bigger than manual solder 6 ～ 8 times) , electric arc quantity of heat is big, welding wire is fused fast, frit is deep big also, solder many rate is rapidder than manual solder. Board thick the automatic solder under 30 millimeter can not open groove, and solder be out of shape small. (2) welding flux layer is good to the protection of welding line metal, welding line quality is so good. (3) managing rolled steel and electric energy. Plate thickness is commonly when 30 millimeter are the following, bury arc automatic solder can not open groove, this saved rolled steel greatly, and be being protected by welding flux as a result of electric arc, make the heat of electric arc gets making full use of, saved electric energy thereby; (4) improved labor condition. Except reduce amount of labor besides, because arc light cannot see when automatic solder, solder the aeriform amount that issues in the process is little, eye of solderer of this pair of protection and healthy it is very beneficial. Bury arc the defect of automatic solder is to get used to ability to differ, can solder in horizontal position only the link welding line of long straight welding line or big diameter. CNC Milling
