Information
1, the phenomenon of
The welding process is mixed with impurities such as traditional Chinese medicine skin and other impurities in the molten pool.
2. Cause analysis
The cleaning of the welding parts is not clean, the coating of multi-layer multi-channel welding layer is not clean, and the skin of the Chinese medicine is in the middle of the melting pool.
The arc length, the welding Angle is not correct, the welding layer is too thick, the welding line energy is small, the welding speed is fast, and the molten impurities in the molten pool have not surfaced and the molten pool solidifies.
3. Prevention and control measures
(1) welding sampes crevasse around 10 ~ 15 ㎜ within the scope of polished surface is clean, until a metallic luster;
When multi-layer multi-channel welding is done, the skin of interlayer is cleaned;
The welding rod is roasted according to the requirement, not using the partial core, dampness, etc.
Using short arc welding as far as possible, select suitable current parameters;
The welding speed is suitable, not too fast.
4. Governance measures
Clean up the surface thoroughly before welding.
Good practice, good welding skill, strong sense of responsibility;
In the process of the detection of the defects found in the detection of the defects, such measures are taken.
