Mold plays an extremely important role in modern industrial production, and his quality directly affects the quality of the product. Increasing the service life and life of the mold and shortening the production cycle of the mold are technical problems that many enterprises urgently need to solve. In the process of production and use of molds, technical problems (collapse, deformation, cracks, wear, pores, etc.) often occur. Therefore, it is also necessary to repair the mold (welding).
Precision welding machine developed by Shanghai Langxian Company. Based on the technology of argon welding, major technological innovations and breakthroughs have been made. The precision of the weld repair is comparable to that of laser welding. It combines the advantages of argon welder and laser welder in repairing. It is a high-tech product that is easy to use and flexible, with high welding precision, small heat impact and fast speed. Therefore, it satisfies the technical needs of customers for repairing molds, castings and various workpieces.
At present, in the industry of repairing molds, the commonly used equipments are: laser welding machine, argon arc welding machine, cold welding machine, and the like. Now the difference between our company's WS series repair welding machine is as follows:
(1) Laser welding machine:
Advantages: high welding precision, small heat affected area, suitable for repair of precision molds.
Disadvantages: 1. The diameter of the wire is relatively small, generally 0.2mm and 0.4mm. It is difficult to repair the work with a slightly larger weld repair amount. Therefore, the welding wire is relatively expensive and the efficiency is relatively low.
2, large size, inconvenient to move, not suitable for on-site operation.
3. The welding repair needs to be operated on the workbench. The slightly larger molds and workpieces cannot be operated.
4, the damage in the welding line is more convenient, but for the irregular shape of the defect, welding is more difficult.
(2), argon arc welding machine:
Advantages: The welding consumables are all full and the repairing speed is fast.
Disadvantages: 1. The heat affected area during welding is relatively large, and the probability of the workpiece being easy to cause (down, deformation, undercut, etc.) is relatively large. Especially when it is closed, it is difficult to grasp, usually with welds, or one week of welding.
2, the welding repair accuracy is low, the mold for high precision requirements can not meet the welding requirements.
3, more mold welding repair requires preheating, heat preservation and other processes, which is cumbersome and time consuming.
4, need a wealth of operational experience, welding in a special place.
(3) Cold welding machine:
Disadvantages: 1. Welding precision and smoothness are low
2, the welding material is relatively small, generally only use nickel-based welding wire or tungsten carbide.
3. The welding repair speed is slow and does not meet the needs of rapid production in the factory.
4, the degree of bonding after welding is low, prone to detachment.
(four), WS repair welding machine features:
1, very high welding accuracy
Since the output current and time of the welding machine are precisely controlled, the current (2-200A) and time (1-500ms) can be adjusted arbitrarily, and the 2A small current can be stably operated. Therefore, even 0.1mm, 0.2mm welding wire can be used. Get the perfect welding. Meet the welding precision of the laser welder.
2. Minimal welding compensation impact Due to the adoption of patented technology, the arcing current and time of the welding machine are reduced several times compared with the common argon welding, which overcomes the impact on the workpiece during the welding repair process, even if there is no machining allowance. The machined surface of the workpiece can also be repaired.
3, very small thermal impact Because the welding current and time are accurately controlled, the input energy can be accurately controlled to ensure that the input energy is only enough for the fusion between the wire and the workpiece, there will not be too much The energy acts on the workpiece, so that the surface of the workpiece is affected by heat to a minimum to achieve the desired repair effect.
4, very high degree of bonding The welding machine after welding has a very high degree of bonding, can achieve the degree of argon arc welding. Can be applied to a variety of processing methods, there will be no other types of cold welder after welding is not strong, falling off and so on.
5. It is suitable for welding repair of different parts, welding of holes, holes and holes in plane parts.
B, slits, grooves.
C, angular, squall line, peak area.
D, sand holes and depressions around the ordinary argon arc welding.
E. Mold after repair welding, nitriding and soft nitriding.
6, the output control is accurate, using 64 for cpu control, intelligent storage, the average person can be operated with a little training, in addition its flexibility and wide adaptability make it favored by the market.
7. A wide range of welding consumables can be used for various welding wires with a diameter of 0.1-2.0 mm below HRC62. Perfect welding can be obtained for all kinds of tools below HRC62. The combination of various functions allows for perfect weld repair after chrome plating of the mold after nitriding and at the edge of the edge.
