成本；现在将波纹管改为不锈钢管，破损的地方就可以使用凿子或机加工取出覆盖铝，露出不锈钢管后重新焊接一个连接头，再用波纹管从外面连接就行。3. The buried cooling water pipe is a bellows. In the past, when the abnormality occurred during the processing or use, water leakage occurred on the water pipe. The wall thickness of the bellows was only 0.8mm, and it was impossible to weld the damaged part. When the chisel or machining is removed, the bellows collapses. If the flame is heated by heating, the whole casting is heated to 500° or more and then the local place is heated to remove the damaged corrugated pipe. This process needs to abolish the entire circuit and cause the mold to be heated. Body deformation and thus increase
Cost; now the bellows is changed to a stainless steel tube. In the damaged area, the covered aluminum can be removed by using a chisel or machining. After the stainless steel tube is exposed, a joint is re-welded and then connected by a bellows from the outside.
