2. Argon arc welding is divided into arc welding and solution welding. One of the biggest differences between argon arc welding and cold welding machine is that when welding, the temperature of the workpiece is relatively high, which will cause the workpiece to be welded to anneal and deform.
3. The role of cold welding machine:
(1) mold repair cold welding machine, casting defect repair cold welding machine, repair machine, metal defect repair machine, tool and mold repair machine, electric spark machine, electric spark cold welding machine, electric spark intensifier, tapping machine, wire and cable cold welding machine, how to repair sand holes on workpieces, and precision mold repair cold welding machine to repair aluminum alloy \ cast aluminum \ aluminum wheel hub; Repair defects of aluminum parts, metal parts and castings; Mold repair machine; Repair of mould wear defects; Enhanced repair of EDM metal surface: EDM coating cold welding repair, casting pit defect repair, all conductive metals can be repaired. In the process of repair, your base metal has no temperature, thus realizing real cold welding. Cold welding machine is a tool to repair and strengthen the surface defects of tools and dies by using cold welding repair technology. Mold repairing machine can repair a few defects of tools, molds, castings and mechanical parts, such as machining defects, collision damage, argon arc welding deficiency, casting defects and accumulated wear. It is a favorable tool for improving product quality, reducing production cost and prolonging equipment service life in mold industry, foundry industry and other related industries.
(2) the characteristics of the mold repair machine:
A. high welding strength: fully welded, able to withstand all kinds of vehicles,
Milling, planing, grinding and other mechanical processing will not fall off.
B. The repair accuracy is high: the minimum repair amount is 0.03mm, without losing the original appearance.
Benchmark, less solder waste, no hard spots, easy to form in the later stage.
C. Scope of application: ferrous metals and non-ferrous metals.
D little damage to the matrix: small hot spots, unchanged metallographic structure of the matrix, no stress concentration, no deformation and no cracks.
4, the purpose of argon arc welding machine:
Argon arc welding can weld almost all metal materials, especially metals and their alloys with active chemical properties. Usually used for welding aluminum, magnesium, titanium, copper and its alloys, low alloy steel, stainless steel, heat-resistant steel and so on. Suitable for welding oxidizable nonferrous metals and alloy steels (currently, aluminum, magnesium, titanium and their alloys are mainly used for welding stainless steel.
