What should be paid attention to when welding steel pipes

1. Cleaning of steel pipes.
Note that before welding steel pipes, cleaning work must be done first. The surface of the steel pipe may have various oils, paints, water, rust, etc., and may also be mixed with various impurities. To ensure the smooth progress of welding and reduce safety issues, it is recommended to clean up these impurities first, which can also help the sealing of the weld joint and reduce the possibility of problems during welding.

2. Adjust the opening.
The welding groove should be based on the wall thickness of the steel pipe itself. If the wall thickness is thicker, it can be opened a little larger, and if it is thinner, it can be appropriately smaller. It should be adjusted according to the actual situation. If you think the groove is a bit large, you can leave a smaller gap on the product. Usually, the product gap is about 1-1.5 times the diameter of the welding rod or welding wire. It can be based on the specific situation of the steel pipe.

3. Welding treatment.
At present, it is recommended to use a half-and-half form for the welding of steel pipes. Don’t be too impatient. What matters is meticulousness and rigor. You must be able to weld the steel pipe in place. If the wall of the steel pipe is thicker, you can choose to process it in layers, which can also have a more stable effect. When dealing with steel pipe welding, you must grasp all aspects of the matter and strictly follow the step requirements. This can relatively reduce the risk problem and ensure the smoothness of steel pipe welding.
