For Weihua lifting equipment, the problem of boom deformation can be achieved by welding repair, which can reduce the scrap rate of equipment and increase the frequency of equipment use, which also saves a lot of cost.
1. material aspects
If you want to repair it, you need to understand the shape and material of the deformed boom. Generally, there are rectangles, pentagons and polygons, and the material selection of the boom must meet the requirements of the bending strength index of the crane.
2. preparation before welding
The deformed part shall be processed and arranged before welding. After the deformed boom is disassembled, the deformed part of the grooved plate and the web is cut by a gas cutter, and the cut portion is polished as shown above. Remove the exterior paint and all kinds of stolen goods, place the cut jib on the hydraulic press for shaping, straighten the treatment, and fix it on the platform with clips.
3. welding type
When welding, it is necessary to ensure penetration and easy processing. Since the material thickness is more than 6mm, it is necessary to open the groove by manual arc welding, which is flexible and convenient for application. Mainly for butt welding, using manual arc welding, the welding type is single-sided welding double-sided forming.
In summary, when Weihua lifting boom deformation is repaired, you can take the approach described in the above series. If you think that this professional operation requires after-sales technology, you can contact the manufacturer. Welcome to buy crane equipment.
