Copper and Copper Alloy Welding Techniques

Copper and Copper Alloy Welding Techniques Points : Copper and Copper Alloy Welding Techniques The outside are methodically clean with the edges are ready according to thickness. Blowpipe is held at 60 to 80° angle and the rod is 25 to 30°, to preserve the heat as much as feasible great care have to taken to keep tip of the inner cone 6 to 9 mm gone as of the molten metal, as the weld is then in an cover of reducing gases which stop oxidation. The weld proceeds in the left ward manner, by a slight sideways motion of the blowpipe. Shun agitate the molten metal and do not eliminate the rod as of the flame but keep it in molten pool. After welding light preening, perform as the weld is still hot amplify the strength of weld. Annealing if necessary can he passed out by heating to 600 to 650°C.
