The existing 60*60 standard cast iron plate, above 3 hard alloy welding specifications, probably in the 30*30, in which the appropriate welding method, know the friends willing to enlighten ah, thanks in advance.Some friends have said the binder is a copper brazing, the basic can be settled. As far as I know, many methods such as welding, high frequency welding, oxygen welding, I want to find a kind of welding method. The key is to understand the trouble with us, surface and surface welding
Welding hard alloy is the most used for brazing, welding of copper wire.
Then an old welder re - welded it once, and it worked out just now. Probably the main point is water welding, the flame can not blow the time is too long, alloy hair red, you have to immediately with the matrix together, right, not only faster, more important still prevail. Because it's not good to come second times if you're not allowed
Light of copper is not enough, but also a deoxidizing agent, is the most commonly used colophong powder. In addition, there must be a certain level of operation, because I have seen a lot of welding ordinary turning tools, in the work of the alloy head always fall.
