Regarding the use of the Xinfengxiang automatic welding machine, a specialized manufacturer of welded pipe machines in Yangzhou, high-quality welding performance requires strict quality standards for the pipes themselves. Precision welded pipe machine equipment requires the following conditions
Xinfengxiang Welding Pipe Machine Group, a professional manufacturer of welding pipe machines in Yangzhou, has strict quality requirements for the pipes themselves to ensure high-quality welding performance when using this automatic welding machine. Precision welding pipe machine equipment requires the following conditions:
1. If the surface of the workpiece is not clean, pores will appear during welding, affecting the welding quality.
2. The bevel of the pipe should not be too large. Generally, the chamfer ≤2mm, with 1mm being suitable. If the bevel is too large, the pipe material is easily burned; if it is too small, the penetration depth will be insufficient.
3. Secondly, the cleanliness of the pipe and pipe plate is required to be high. The pipe plate should be cleaned with alkaline or organic solutions, and the pipe should be polished with sandpaper until a metallic luster is visible.
4. The elongation of the pipe is longer than that of manual welding, generally 4-5mm is optimal. If it is too long, the weld penetration depth will decrease, and the weld will not be aesthetically pleasing; if it is too short, defects such as undercutting and pipe mouth damage will occur.
