Groove types for automatic stainless steel welding
Thread Content
Groove shape for automatic stainless steel welding: A welding process for 34mm stainless steel by automatic welding is to be carried out. The welding supervisor said that the groove should be asymmetrical – the depth on the inner side (the side that is welded first) should be 23mm, with a bevel of 4mm in the middle; the depth on the outer side (the side that is welded later) should be around 7mm. If this is not done, the appearance of the weld will be poor, and it may collapse inward. Is that really the case? Who has experience in this area
It may be due to personal experience; it is also necessary to consider uniform stress distribution on the inner and outer surfaces.
This is a relatively common type of welding; such a groove is feasible, as it saves welding material and reduces the difficulty of welding. But the blunt edge in the middle should still be smaller.
This type of groove is fine, but for 34mm stainless steel, a narrow-gap U-groove should be considered.
