Features |
This machine can instantly release the electric energy stored in the capacitor between the tungsten electrode and the workpiece in the form of a pulsed arc. The extremely high temperature arc makes the workpiece and the welding wire composed of metal materials rapidly melt and weld together to achieve the purpose of welding repair. . The characteristics of this welding repair method are: the time is very short and the calorific value is very small This welding machine can complete the welding process of welding wire and workpiece within tens of milliseconds, so as far as the workpiece matrix is concerned, the heat generation is less, the temperature rise of materials other than the welding point is small, and annealing and discoloration will not occur. Since the molten pool volume generated by each welding pulse is less than 2mm3, the resulting stress is also small. Although a welding requires many molten pools to be combined, because the stress direction of the solder joints is dispersed, the concentrated stress on the workpiece is small, so the workpiece does not deform or discolor after welding (you can directly touch it after welding). Weldable repair materials: In addition to zinc, tin and other materials with very low melting points and hard alloys, workpieces made of various metal materials (including copper and aluminum) can be welded. |
