Due to the external factors, there are sometimes bubbles in the welding of color coated plate, which will make the welding not firm but also affect the aesthetic degree. Therefore, we should try to avoid this situation when welding. If the bubbles are not avoided in time, it is easy to cause some problems in the subsequent use. What are the causes of this phenomenon What about it? Only by finding the reason can we solve it better. Let's explain to you the causes of bubbles during welding:
1. If the surface of the color coated plate weld is not cleaned, it is easy to cause bubbles, such as oil, water and other components. In this regard, we can solve this problem by cleaning the surface to be welded.
2. Impure shielding gas can also lead to bubbles, so 99.99% argon can be used to deal with this problem.
3. If the end of welding wire is exposed to air, there will be bubbles. Therefore, when welding the color coated plate, we should keep the end of the welding wire under the protection of inert gas
The above three points are the causes of bubbles during the welding of color coated plates. In fact, the reason is very simple. You can pay more attention to it during the operation. The cause of bubble phenomenon is often caused by the operation not meeting the requirements, so it is very important for everyone to master the correct operation method. Do a good job in the surface cleaning of the plate, and ensure that the surface is free of dirt before welding, which can well avoid the generation of bubbles.
