Welding equipment types folding 1. cold welding cold welding is the use of high-frequency spark discharge principle, no heat welding workpiece. Cold welding of metal parts can occur wear, scratches, pinholes, cracks, deformation defects, reduce the hardness, trachoma, damage and other defects deposition, sealing, make equal repair. Simple, low heat input, instant process without welding heat input, thus mold deformation, annealing, undercut and residual stress soldering equipment where good Huizhou Hua Shi, does not change the state of the mold or product metal structure, high precision repair coating thickness from a few microns to several millimeters, only grinding and polishing. Can also be turning, milling, planing, grinding and other types of machining, and electroplating and other post-processing. Welding Equipment (1) manual arc welding equipment. Manual arc welding equipment is simple to use, the method is simple and flexible, adaptable, but the welder high operating requirements. Hand arc for welding carbon steel, low alloy steel, stainless steel, copper and copper alloys and other metal materials. (2) SAW device. Submerged arc welding equipment from power, submerged arc welding machines and auxiliary equipment constituted. Its power can be AC, DC or AC-DC and use. Submerged arc welding machine into automatic and semi-automatic welding two categories. ① semi-automatic submerged arc welding machine. ② automatic submerged arc welding machine. (3) CO2 gas shielded arc welding equipment semi-automatic CO2 gas shielded arc welding equipment consists of welding power supply, gas supply systems, wire feeder and welding torch and other components. (4) inert gas welding equipment manual inert gas welding equipment, including torches, welding power and control devices, gas and water supply systems of four parts. (5) plasma arc welding equipment, plasma arc welding equipment including welding power supply, control systems, welding torch, gas system and water system. Main power circuit by resistance welding transformers, SCR unit, the main power switch, soldering circuits and other components. Welding equipment now we use the power of 200kVA, secondary output voltage 20V - 40V AC single-phase power frequency resistance welding machine. Due to a variety of models collinear production, welding clamp to be welded high-strength steel and low carbon steel sheet, welding clamp gun arm to pass greater mechanical strength and high-frequency welding equipment, welding current production - Huizhou Hua Shi, so the strength of welding tongs stiffness, fever, welding equipment must meet certain requirements, and to have good electrical and thermal conductivity, and requested the use of water cooling welding clamp, welding clamp electrode arm so I chose to be able to withstand the pressure of the new welding clamp 400kg.
