我局5吨高锰钢抓斗上的镶齿原是镇静钢材质,因长期使用已被磨损,需重新用高锰钢锻打成500毫米长、80毫米厚的方形齿焊在高锰钢抓斗的基体上。但由于曾多次镶焊过其他材质的斗齿,致基体镶齿处的材质较复杂,给焊接加工造成一定的困难。经过反复试验,终于用冷焊的方法成功地焊接了高锰钢抓斗。两年来的使用表明,效果很好。焊接过程如下:先用“奥202”或“奥207”不锈钢电焊条在镇静钢上堆焊一层(过渡层),在该堆
I Board 5 tons of high manganese steel grab on the original is to calm the steel, because of long-term use has been worn, need to re-use high manganese steel forged into 500 mm long, 80 mm thick square tooth welding in high manganese steel Grab the base. However, due to repeatedly inlaid with other materials of the teeth, resulting in matrix material at the dentures more complex, to the welding process caused some difficulties. After repeated tests, finally with a cold welding method successfully welded high manganese steel grab. Two years of use shows that the effect is very good. Welding process is as follows: first with “Austrian 202” or “Austrian 207” stainless steel welding electrodes in the cast steel surfacing layer (transition layer) in the pile
