How to prevent false welding during the welding of 304 stainless steel square tubes?

2. Mill the connecting parts before welding. Use a milling cutter to treat the contact surface of the connector to ensure sufficient contact and fusion during welding. When welding, attention should be paid to ensuring that the excess length at one end does not exceed 200mm to avoid uneven welding and virtual welding.

3. Control heating and collision speed. If the heating and collision speed is too fast, the melted part of the connector may be squeezed onto both sides of the inner and outer walls, causing insufficient fusion and resulting in virtual welding. During the processing, the speed of the machine should be controlled to ensure full fusion of the fusion.

In summary, to prevent false welding during the welding of 304 stainless steel square tubes, attention should be paid to the quality and suitability of the docking fixture, milling treatment should be carried out, and heating and collision speed should be controlled. Only when the technical operation is mature can the occurrence of virtual welding be effectively reduced.
