Metal defect repair welding

DYH-200 precision repair machine DYH-200 is a high-precision precision fill welding fill welding professional production company for mold, casting and welding various parts of the welder welding laser welding accuracy can be achieved precision, but also has a higher speed and flexibility, is a high practicality of repair equipment, repair industry, real helper. The welder set a higher two practical functions: 1, 2 precision pulse spot welding, a continuous pulse welding, spot welding precision pulse characteristics: 1, high-performance TIG: 2A small current stable arc, it is universal TIG welding of high-end products. 2, high precision welding welder As the output current, time to get precise control, current (2 -200A), time (1-600ms) range can be adjusted, 2A low current stable operation, it can be Depending on the welding requirements, set the corresponding parameters, even 0.1 mm, 0.2mm wire also available perfect welding, to achieve precision laser welding welder. 3, minimal impact due to the use of patented welding technology, welding arc current and time than the common lower multiple of argon welding, welding process to overcome the impact of the work, even for no allowance machined surface of the workpiece can be patched. 4, minimal heat affected due to the welding current, time to get precise control, to ensure that the energy input is only enough for fusion between the wire and the workpiece will not have too much energy to act on the workpiece, so that the surface of the workpiece affected by heat to a minimum, to achieve the desired effect patch 5, combined with extremely high degree of binding of the welder after welding, to achieve the effect of argon welding, for a variety of processing methods, does not appear in combination is not solid, off and so on. 6, for different parts of the welding A, flat parts of depression, hole, hole welding. B, slit trench. C, angular, flute line, spikes site. D, trachoma and general welding surrounding depression after two consecutive pulse welding suited for thermal effects on the blank is not very high, this work can greatly improve efficiency, by providing a unique time interval function to reduce heat affected several times, so as not to appear burn burn through phenomenon. Basic parameters: Input Power AC220V rated output power 4KVA maximum no-load output voltage of 65V current output range 2-200A Pulse Time 1-500ms continuous pulse interval 200-1200ms gas delay time 6ms applicable 1.0-3.0mm Tungsten diameter cooling fan forced air cooling Dimensions 470mm × 265mm × 400mm Weight 38KG Application: Welding 2. All kinds of mold casting defect repair 3. component repair a workpiece, mold injection mold stamping die casting mold copper alloy, aluminum die two , ductile iron foundry industry, gray Tie, stainless steel, the welding, copper, aluminum defect repair. Third, the workpiece parts machinery parts, auto parts, shafts, gear type, pumps, valves. Welding characteristics: A, small heat affected zone. B, without preheating process, the workpiece is not annealed after welding. C, no deformation and collapse edge D, no porosity and trachoma E, accurate and precise, can weld small and sophisticated geometry area, the smallest wire available to 0.1-0.2mm. F, easy to use and flexible, can be directly on-site repair, remove or repair the part of the workpiece to make expensive separation work. G, can be used for cracks, collapsing missing, angular, sand holes and use the repair of worn. H, using different hardness material, available in different hardness after welding (eg 60HRC). The tough opening to Die and tool edge can also be welding, eliminating the tedious common TIG welding preheat, thermal insulation process, improve the quality and efficiency of repair.
