要注意的项「概要耍汀三意的项月概要避免相对壁厚差大的部分的焊 焊接是使其局部快速加热后通过烨条的熔敷全属将两侧熔敷在一起的。因此,如果烨接邸位l匆侧的壁厚有大的差别,则山于其热齐量之差而发生熔敷时温度、熔敷后的冷却速度之差,容易形成熔敷不完全 两者的壁厚差大时, Summary of Key Points to be Observed Summary of the Month to Avoid Welding The part where the relative wall thickness difference is large is welded so that the two parts are welded together by the entire fillet of the fillet after rapid local heating , If Yupu di bit hash side of the wall thickness has a big difference, then the mountains in the amount of heat difference occurs when the welding temperature, the difference between the cooling rate after welding, easy to form the two are not welded When the wall thickness difference is large,
