In order to avoid this situation, we also used nickel or copper wire as welding accessory material to weld the lease of impact crusher. But many careful customers will find that impact crusher lease. In the process of production, small pore will develop into a state of crack. In fact, this is not the case. Crack is a very dangerous defect in welding connection.
According to the time of generation, it can be divided into hot crack and cold crack. The former is produced during welding, and the latter is produced during or after cooling of welding seam. In welded structures, cold cracks are often a serious quality problem during service. So this is also a problem we attach great importance to. We are trying to avoid these two situations when we carry out quality inspection of equipment. We have strict requirements from the whole production line.
