机器上许多零部件因长期工作而出现磨损,一般磨损量不允许超过0.5～1.5mm,否则就要进行修复或更换。目前对磨损后的修复广泛采用的是电弧焊、气焊、等离子焊、喷涂、涂镀等方法。这些修复方法各有其缺点,只能修复磨损零件的某一方面的缺陷。我们现在向您介绍的接触焊修复新工艺,是采用粉末金属接触焊修复零件表面,很容易实现修复工艺的自动化。采用接触焊工艺修复工件时,由于被焊零件的金属和焊接金属粉内的强 Many parts of the machine wear and tear due to long-term work, the general wear and tear does not allow more than 0.5 ~ 1.5mm, otherwise we should repair or replacement. At present, widely used after wear repair arc welding, gas welding, plasma welding, spraying, coating and other methods. Each of these repair methods has its own drawbacks, which can only repair some defects of the worn parts. We now introduce to you the new technology of contact welding repair, which is the use of powder metal contact welding repair parts surface, it is easy to automate the repair process. The use of contact welding process to repair the workpiece, due to the welding of metal parts and welding metal powder strong
