quality BL Flange manufacturers products Production Process

quality BL Flange manufacturers products The forging process generally consists of the following procedures, namely, selecting high-quality billets for blanking, heating, forming, and cooling after forging. Forging methods include free forging, die forging and membrane forging. During production, different forging methods are selected according to the quality of forgings and the number of production batches.

Knowledge of flat welding

For T-shaped joints, Angle joints and lap joints with small welding foot size, single-layer welding can be adopted, using straight line or oblique serrated, oblique ring strip method. When the size of the welding foot is large, multi-layer welding or multi-layer multi-pass welding is generally adopted. The first layer adopts the linear running bar method, and the other layers can adopt the oblique ring and sawtooth running bar. For multi-layer and multi-pass welding, the linear conveyor is generally used.
