FAULT REASON AND REPAIR METHOD

When checking the rust cracks of the welding seam on the side plate of the excavator arm, it is necessary to scrape off or polish the surface paint layer and rust of the welding seam. When observing, tap the welding seam with a small hammer, and use a magnifying glass to observe if necessary.
1. Cause of cracks
Reasons for cracks on the side plate of the excavator arm: including bubbles, slag inclusions and tiny cracks in the original weld. When the excavator is overloaded, tiny cracks will occur at the original weld and slowly expand: the welding rod Cracks that do not match the performance of the plate: Due to the large size of the excavator arm, it is difficult to adopt reliable and effective heating and heat preservation measures. During the operation, the vibration and impact are relatively large, and the uneven force at the welding seam causes the welding seam to crack.
2. Repair method
Preparation work before welding: remove oil, paint, rust, etc. from the original weld crack with a hand grinding wheel. Use a gouging machine to cut off the weld crack, plan to the body of the side plate, and remove the hardened area of ​​the base metal that was welded in the past. After planing, use an angle grinding wheel to smooth the incision (the inner interface is ground to form a V-shaped groove), after cleaning and pink inspection, confirm that all cracks have been found and removed.
