How to heat the steel wire cut shot

The steel wire cut shot manufacturer introduces the heat treatment method of the steel wire cut shot:

The heat treatment method eliminates the residual stress of the steel wire cut shot welding. In addition, the heat treatment process makes the steel wire cut shot weld area and heat affected zone, the material hardens, the embrittlement structure has been softened, and the strength, toughness, and annealing are formed to improve the weld joint Toughness and fracture toughness materials; Liaoning alloy steel shot

As for the residual stress of the cut steel wire shot, it can be fully reduced; the post-weld heat treatment method to eliminate the welding residual stress can be divided into two processes, that is, the heating of the cut steel wire shot and the heat preservation process of the cut steel wire shot; in the process of heating the cut steel wire shot, welding is used as weak The residual stress at the yield point of the material reaches the temperature of the post-weld heat treatment, reducing the residual stress is the yield point of the material below this temperature;

In the heat preservation process, the reason for the welding residual stress caused by the creep phenomenon (high temperature relaxation) and the influence on the welding process parameters are analyzed and the structural characteristics of the residual stress are considered. The steel wire cut shot is used after the welding heat treatment. The method to eliminate the welding residual pressure of the key parts of the protective door, and achieved good results;

Because the direct combustion method consumes more fuel, in the process of heating the steel wire shot, welding is used to weaken the residual stress of the material's yield point, reaching the temperature of post-weld heat treatment, and reducing the residual stress is the material with the yield point below this temperature;
