爆炸焊接在我国还是一种新的焊接方法,它可以将两种大面积的金属板焊接成双金属板。我厂大电流石墨化炉导电母线和铜铝母线接头,原先采用螺栓直接压接,经过几年运行接触面电腐蚀严重。我们采用爆炸焊接新工艺,爆炸成300×300×20mm铜板与300×300×3mm铝板的双金属过渡板。现在已用于石墨化炉,解决了铜铝直接压接电腐蚀严重的问题。铜铝过渡接头的接触电阻为铜铝直接压接电阻的四分之一;稳定性好,经一年的运行,接触
Explosive welding is still a new welding method in our country, which can weld two kinds of large area metal plates into double metal plates. I plant large current graphitization furnace conductive busbar and copper and aluminum busbar connector, the original direct pressure bolt, after a few years run contact surface serious electrical corrosion. We use explosion welding new technology, exploded into 300 × 300 × 20mm copper and 300 × 300 × 3mm aluminum bimetallic transition plate. Now used in graphitization furnace, solves the serious problem of direct corrosion of copper and aluminum. The contact resistance of copper-aluminum transition joints is a quarter of the direct crimp resistance of copper and aluminum; good stability, after a year of operation, contact
