Information

1. First, the elongation of the pipe is longer than that of manual welding. Generally, 4-5mm is better. If it is too long, it will reduce the weld penetration and the weld is not beautiful; if it is too short, it will cause undercuts and damage to the nozzle. And other defects.

2. Secondly, the cleanliness of the pipe and tube sheet of the pipe welding equipment is higher. The tube sheet is best cleaned with lye or organic solution.

3. The appearance of the welding workpiece is not clean, and air holes will appear during welding, which will affect the welding quality.

4. The pipe bevel should not be too large, the general chamfer is ≤ 2mm, and the best is 1mm. If the bevel is too large, it is easy to burn the pipe, and if it is too small, it will cause insufficient penetration.

Yangzhou Donglun Industrial Equipment Co., Ltd. is a professional manufacturer specializing in the production of various specifications of high-frequency welded pipe equipment, slitting units, Kaiping units, and cold rolling metallurgy equipment.
