process parameters: considering the characteristics, production efficiency and dilution reduction of the main cutter disc, the surfacing electrode 4102 was selected with the electrode diameter ±4mm.Arc stable ax5-500 dc welder.Dc reverse connection, welding current 160A, welding current and (2)
1. Remove scale, rust, moisture and grease of the parts to be welded before welding.
2. If the main cutter plate is welded after bucket surfacing welding, it is difficult to correct the deformation and deformation of the main cutter plate caused by surfacing welding.Therefore, the main cutter should be surfacing before assembly and welding to the bucket.
3. As the main cutter plate is long and thin, it is easy to cause deformation in the surfacing welding process, so it is difficult to correct.In order to prevent welding deformation, it should be fixed on the metal frame with high constraint before surfacing, and the method of split type and split type back welding should be adopted for welding.
4. In order to improve productivity and reduce dilution rate, downhill welding should be adopted.
5. When the overlaying welding deformation of the main cutter plate, flatten it with hydraulic press.
After surfacing, the hardness of the surfacing layer should be greater than HRC50.
