There are several types of welding repair:If the fillet leg has a relatively small size, multiple multiple welds can be used, like a swallow's nest, from bottom to top, layer by layer to size requirements.

2. If the welding Angle of the fillet weld is not large, less than 4-7mm, and the size of the welding foot is insufficient, it shall be scraped or polished and welded again.

3. If there are any welding defects (such as porosity, slag inclusion, crack, incomplete penetration, etc.) in the welding seam, the defects shall be cleaned and the butt joint shall be chamfered before welding.When opening the groove, note that the groove Angle is 60 degrees.The surface of the groove should be cleaned of metallic gloss to avoid sharp corners.If necessary (for cast iron welding), stop drilling.

4. During welding, pay attention to that the welding thickness is not super 3-5mm, and clean the interlayer.
