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、气孔。在全位置焊中应用自动焊接设备时，气孔是一种比较常见的问题，导致该问题产生的原因有很多，比如焊材自身的原因、操作不当、环境原因等。

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.

鉴于此，为有效地防止这一问题，在实施焊接时，应加强气体的保护，焊接温度不可过高，严格按照比例以及相关要求来充装气体，确保充装纯度达到要求。同时还要注意施焊场地周围的环境，若施工场地的风速每秒超过8米，应用防风棚来实施防护，且环境湿度不可过大。此外，为确保施焊位置保持干燥，可利用环形火焰加热器或中频感应加热器来实施加热。

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、未熔合。环缝自动焊接设备在焊接过程中，未熔合这一问题一般常出现于立焊位置，导致该问题的原因有焊道打磨形状不正确、在焊接时偏离焊缝或者焊枪摆动的宽度不够合理等。鉴于此，在焊接过程中，在实施焊道打磨作业时，应尽量打磨平整。

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.

同时在焊接之前，还应对焊丝进行仔细地观察，察看其摆动宽度是否正确。此外，在焊接过程中，如发现焊接熔池和焊道中间出现偏离，应及时实施调整，以免出现未熔合问题。

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.

以上就是小编为大家介绍的如何防止环缝自动焊接设备的焊接失误，希望为大家带来帮助！

The above is a small series for you to introduce how to prevent the welding error of automatic welding equipment, hope to help you!
