In view of the defects on various types of Fully Automatic Combustion Boiler Grate, the repair method should also be flexibly selected and applied.
TIG welding: Precision castings and aluminum alloy die castings are mostly repaired by TIG welding machines. Some mold manufacturing and repair manufacturers also use this welding machine to repair mold defects. Advantages: high welding repair efficiency and higher precision than electric welding machines. There are many types of welding wires, which are widely used in stainless steel and aluminum alloy products. The Fully Automatic Combustion Boiler Grate can be used for welding with high strength. Disadvantages: used for defect repair. When repairing small defects, there are traces on the edge of the molten pool due to excessive impact. Welded steel parts have hard spots. Due to thermal effects, thermal deformation is easy to occur when welding non-ferrous castings or thin-walled parts. Operational technical requirements are high. Electric welding machine: the traditional method used for welding and repairing cast iron and steel castings. Advantages: Repair large defects, high efficiency. Disadvantages: The hardness of the solder joints after welding is too high, and there is internal stress, which is prone to cracks. Generally, annealing heat treatment is required to meet the processing requirements. And due to the limitation of welding conditions, secondary defects such as pores and slag inclusions are easily generated inside. Mounter: The principle of instantaneous high-frequency discharge is used to paste the solder tab on the surface of the workpiece. The thickness of each paste is equal to the thickness of the solder tab. The welding quality depends on whether the discharge is uniform or not. It is suitable for workpiece wear and processing out-of-tolerance repair, and has a certain influence in the mold market. The machine can also fill the solder powder to the defect and repair it after discharge. The chromatic aberration of the repaired workpiece is small. The downside is that patching is slower. Cold welding machine: It is a new repair technology in the early 21st century. Because the heat generated by the workpiece during the welding repair process is extremely small, it is called a cold welding machine.
After several years of development, the application direction and technology of Fully Automatic Combustion Boiler Grate have been greatly developed, and it has occupied a large share in the repair market.
