The casting defect repair technology! Castings due to a variety of factors of production and processing, often appear porosity, pore, slag inclusion, defects such as cracks, pits, in the normal casting case download permissible range, but to solve all these problems behind us. Commonly used to repair the equipment for argon arc welding machine, cold resistance welding machine, welding machine, etc. Foundry casting low requirements for the quality and appearance of the casting defects can use argon arc welding machine and other large calorific value, high speed welding machine to repair. But in the field of precision casting defect repair, because of the influence of argon welding heat, caused to repair the casting deformation and hardness decrease, sand holes, partial annealing, cracking, pinhole, wear, scratch, bite, or the binding force is not enough and secondary defects such as internal stress injury. Cold welding machine is to overcome the above shortcomings, its advantage mainly displays in the heat affected zone is small, the casting without preheating, normal temperature cold welding repair, therefore no deformation, bite edge and residual stress, won't produce local annealing, don't change the casting metal tissue state. So cold welding machine is suitable for precision castings surface defect repair. Cold welding scope of welding repair for Φ 1. 5 - Φ1。 2 mm weld points repeatedly melting process of accumulation, in the process of large area of defect repair, repair efficiency is the only factors restrict its wide application. For large defect, recommend traditional welding repair technology and casting defect repair machine composite applications.
