在航空发动机上,不锈钢和高温合金的薄板焊接构件占很大比例。我国大多数采用TIG焊,但是TIG焊的输入线能量大,焊工需双手操作,可达性差,效率低。MIG焊的线能量小,可单手操作,可达性好,效率高,易于实现自动化。为此,我们对MIG焊用于不锈钢和高温合金薄板的焊接进行了工艺试验,并进行了实物 In aeroengines, stainless steel and high-temperature alloy sheet metal welding components account for a large proportion. Most of our country adopts TIG welding, but the energy of input line of TIG welding is big, the welder needs both hands to operate, the reachability is poor, the efficiency is low. MIG welding line energy is small, one-handed operation, accessibility, high efficiency, easy to automate. To this end, we have MIG welding used in stainless steel and high-temperature alloy sheet welding process tests carried out and in kind
