In natural gas construction, the commonly used welding method is hot-melt welding, and the cost-saving welding method is also hot-melt welding, which is also a key welding method. Here is a brief introduction to the key points of attention of hot-melt welding in conventional on-site construction. Simplify the complex color problem.
Main matters needing attention before hot melt welding construction
1. The surface of the heating plate of the hot-melt welding machine should be kept clean, free of pollutants, dust, and polyethylene fusion. Use heating curling hair to clean the heating plate in the following situations.
1) Before the first hot melt welding every day;
2) Before replacing pipes with different diameters before welding;
3) After cleaning the heating plate by other methods;
