It is inevitable that there will be some small mistakes in the welding process of the automatic welding equipment for girth seam, so how to prevent them? Today, the price of Shandong automatic welding equipment for circumferential seam is introduced to you as follows:
1. Stomata. When automatic welding equipment is used in all position welding, air hole is a common problem, which is caused by many reasons, such as welding material itself, improper operation, environmental reasons, etc.
In view of this, in order to effectively prevent this problem, in the implementation of welding, the gas protection should be strengthened, the welding temperature should not be too high, and the gas should be filled in strict accordance with the proportion and relevant requirements to ensure that the filling purity meets the requirements. At the same time, we should also pay attention to the environment around the welding site. If the wind speed of the construction site exceeds 8 meters per second, the wind shed should be used for protection, and the environmental humidity should not be too high. In addition, in order to keep the welding position dry, ring flame heater or medium frequency induction heater can be used for heating.
2. No fusion. In the welding process of automatic girth welding equipment, the problem of non fusion often occurs in the vertical welding position. The causes of the problem include incorrect grinding shape of weld bead, deviation from the weld during welding or unreasonable swing width of welding gun. In view of this, in the welding process, in the implementation of bead grinding operation, should try to smooth grinding.
At the same time, before welding, the welding wire should be carefully observed to see if its swing width is correct. In addition, in the welding process, if there is deviation between the weld pool and the weld bead, it should be adjusted in time to avoid non fusion.
The above is a small series for you to introduce how to prevent the welding error of automatic welding equipment, hope to help you!
