Can weldHowever, due to the high carbon content of pig iron, as well as impurities, manganese, sulfur, etc., conventional welding will result in rough weld, poor toughness. So it must be welded in a special way.Pig iron welding with special welding rod, equipment and methods are the same as ordinary welding.
Can ah, with welding rod, welding torch, welding machine can ah, more training can, and can spot welding, even arc welding, etc., skilled, after all how can
I can tell you 2.1: welding to the welding surface polishing, to prevent impurities, make welding more firmly2: after welding, should be put into the lime, so that it slowly coolingAbove is a wise remark of an experienced personPS: forget to say a bit, welding pig iron must choose special pig iron electrode
