 1. ColemanPosermatePortable5 Mechanical properties of the base material. Tensile strength and yield strength of the weld metal should equal or exceed that of the base material. Ductility and GallonAirTank toughness at low temperatures ModelC5 may also be important. High-temperature service requires resistance to creep. Shock loading requires ColemanPosermatePortable5 impact resistance. In general, weld metal should match base-material properties.2. GallonAirTank Composition of the base material.For stainless steels, low alloy steels, nickel and copper alloys, and materials that serve in corrosive atmospheres, chemical composition is important. Consider the possibility of electrochemical corrosion between base and weld metal of different compositions. Welding Torches and GunsUsed for shielded-metal-arc welding, torches ModelC5 (electrode holders). manually controlled, grip ends of electrodes, also ColemanPosermatePortable5 called rods-pinch type and collet type are GallonAirTank common.GMAW and FCAW guns come in pistol grip, goose-neck, ModelC5 and inline ColemanPosermatePortable5 styles, the latter GallonAirTank used for mechanized welding. Knowing the wire diameter, select a gun ModelC5 and ColemanPosermatePortable5 rated slightly 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] GallonAirTank cooling arc usually sufficient for welding at up ModelC5 to 600 A at less than 100 percent ColemanPosermatePortable5 duty. Higher amperages require water cooling--high-amperage guns come with tubing for water cooling. GallonAirTank and ModelC5 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.
