What are the welding methods for brass and pig iron?
If it is gray iron so in case of violence ran up because of no way to become a local constant temperature of white is because the local temperature changes so as to the molecular structure of two types of cast iron will become no better than mutual acceptance of incomplete fusion simple point to ductile cracking a lotIn addition to iron is a kind of thousands of window holes things warm is a problem once the fire left the heating zone temperature declines immediately without simple local not red gun
When the fire is the key well blew rotten iron also can not do things so the copper parts don't know what you said is completely experience so after a period of time to heat to prevent the temperature difference because of the sudden change and let the workpiece separationSweat!!! It's difficult to explain to you. This experience is bad, especially the fusion phase
I don't know how to tell you how to solder, because most of them need experience and I don't know what you want to weldCast iron welding brass, in the furnace on the cast iron high temperature heating welding, use iron powder to block the honeycomb hole (usually with iron powder, of course, there are professional things used)
