Precautions For Welding Steel Pipes

1. First, ensure that the steel and other raw materials are properly inspected and meet the standards before entering the construction site.
2. Check if the welding materials are qualified and if they are stored according to regulations. Pay attention to whether there is rust on the surface of the welding material. If the steel pipe has already rusted or moldy, it will not be usable.
3. The cleaning of the welding area should be well managed, and the welding area should be kept clean and dust-free. There should be no dirt such as water, oil, rust, etc., and external defects of the weld seam should be prevented.
4. The principle of selecting welding methods is to try welding first and then welding as much as possible. To avoid welding quality accidents caused by misuse of welding wires.
5. Before pre welding, check the groove size first. Pay attention to checking whether the gaps, blunt edges, etc. meet the process requirements.
6. Welding personnel should first clean the slag and check if there are any treated joints when repairing welding work. There should be no oil, rust or other dirt at the groove.
