 Welding Torches and GunsUsed for shielded-metal-arc air and compredsor welding, torches (electrode holders). manually controlled, kit grip ends of electrodes, also called rods-pinch type air and collet type are common.GMAW and FCAW guns come in pistol grip, goose-neck, and inline compredsor styles, the latter used for mechanized kit welding. air Knowing the wire diameter, select a gun rated slightly compredsor higher than the welding current to be used. Duty-cycle ratings are usually given for C[O.sub.2] shielding--air or C[O.sub.2] cooling arc usually sufficient for welding at up to 600 A at less than 100 percent duty. Higher amperages require water cooling--high-amperage guns come with tubing for water cooling. kit Hand-held, mounted on a robot arm or fixed within a mechanized welding setup, guns guide filler wire and shielding gas into the weld puddle. Select hardfacing materials based on weld-deposit microstructure and the wear air situation compredsor the part will encounter, with consideration given kit to thermal treatments applied to the material before air and after hardfacing. Deposit chemistry can compredsor be crucial in attaining the desired corrosion resistance or wear properties, or for minimizing the risk of solidification cracking. Acceptable deposit chemistry kit and air and compredsor is achieved through kit the initial choice of consumables, air using wire analysis and flux composition, and by specifying the number of weld passes needed to compredsor and kit reduce parent-metal dilution to within acceptable limits. With the submerged-arc process, the flux and electrode govern the air characteristics of the applied hard facing. For example, compredsor those fluxes kit neutral to manganese and silicon are not necessarily air neutral compredsor to carbon and chromium, kit elements that matter most in hardfacing.
