1. control welding heat: control welding heat during welding to avoid overheating too fast, and use small current multi-pass welding to reduce heat accumulation and concentration.
2. Suitable welding materials: Choosing suitable welding materials can improve welding quality and stability and reduce the possibility of back collision.
3. Adjust welding parameters: according to different plate thickness and welding position, adjust appropriate welding current and welding speed to ensure welding quality and effect.
4. Using cooling measures: Using cooling measures in the welding process can reduce the welding temperature and heat accumulation, thus reducing the possibility of back bulging.
