The crack in the brazing process is less than the fusion welding, but it can also cause cracks because it is cold. Many high strength materials, such as stainless steel, nickel-base alloy, copper nickel alloy, etc., where brazing and melting of the solder is prone to self-rupture. For example, this phenomenon is quite common when brazing rods for copper and hvac brazing rod.
It is found that this phenomenon is often found in welding parts with heavy hammer or scratches, as well as the welding parts with cold hardening. At the same time, it is found that when the welding parts are rigid fixed or brazing is not uniform, it is easy to be self-splitting. Therefore, the self-rupture in the brazing process occurs when the stress is applied to the solder, where it is wetted by the liquid solder,Of course, the right approach can be avoided.
Xinxiang Qixing Welding Material Co., Ltd. has long provided various high-precision brazing rods, and more problems with solder can be discussed with QiXing brazing experts.
