The solder that bury arc solders process

Of the solder that bury arc solder of process and welding rod arc welding basic and same, heat source also is electric arc, but the welding flux that changes the coating on welding wire into grain shape. Before soldering, scatter welding flux shop on welding line first, 60 millimeter of about 40 ～ are thick, if pursue,1 shows those who be welding line to fashion a process. Graph the formation of the welding line when the 1 solder that bury arc 1- welding wire; 2- weldment; 3- welding flux; Metal of 4- liquid state; Welding flux of 5- liquid state; 6- welding line; When 7- solder broken bits solders, the electric arc between welding wire and weldment, complete adj/LIT wide is buried in 40 ～ 60 millimeter burn below thick welding flux layer. The welding flux that nears electric arc area is fused below the action with hot electric arc, such, grain shape welding flux, fused welding flux surrounds electric arc and bath metal closely, those who make is as completely cut off as outside air. Welding wire sends electric arc the area ceaselessly, move along direction of welding. Electric arc also moves subsequently, continue to fuse weldment and welding flux, form metal of many liquid state and liquid state welding flux. After waiting for refrigeration, formed welding line and solder broken bits. Because electric arc is buried below welding flux, friend says to bury arc solder (say welding flux layer issues arc welding again) . When afore-mentioned processes medium welding wire sends into with welding line of welding wire edge forward shift is operated two kinds when all be being finished automatically by welder, this buries arc namely automatic solder. Bury arc of automatic solder solder the process is shown 2 times like the graph. Weldment interface opens groove (groove can not leave under 30 millimeter) hind, undertake tack welding first, fill up plate below weldment, in order to prevent liquid state metal pour out of. Put through solder when power source begins to solder, send filar annulus by electric machinery drive, welding wire from welding wire dish in pull, and classics is electric implement and send to area of electric arc combustion. Welding flux also fights those who send electric arc the area from welding flux in front. Contain in the two side of welding flux fender lest welding flux to two sides diffuse. Welding line and solder broken bits are formed after solder is over. The welding flux that did not fuse partly, reclaim by welding flux implement suck in returning welding flux to fight, continue in order to have to use.
