1 应用等离子体堆焊的模具 用金属粉末以等离子体堆焊凹模代替比较贵重的合金钢和工具钢。 这种方法的实质是,在型号为yПH—303的等离子体堆焊机上的预热钢圈中往凹模的工作面上堆积一层在形成等离子气流中
1 application of plasma welding die with metal powder plasma welding die instead of more expensive alloy steel and tool steel. The essence of this method is deposited on the working surface of the die in the preheating rims on the plasma torch welder model yПH-303 in the formation of a plasma gas flow
