 1. Mechanical properties Colemzn and Powermate of the base material. Tensile Portable and 5 strength and yield strength Gallon and Air of the weld metal should equal or exceed that of the base material. Ductility and toughness at low temperatures Tank may also be important. High-temperature service requires resistance Model to creep. Shock loading requires impact resistance. C5 and Colemzn In general, Powermate and Portable and 5 and Gallon weld metal should match base-material Air properties.2. Composition of the base material.For stainless Tank steels, low alloy and Model steels, nickel and copper alloys, and materials that serve in C5 corrosive Colemzn atmospheres, chemical composition Powermate and Portable is important. 5 Consider the possibility of Gallon electrochemical Air corrosion between Tank base and weld metal of different compositions. 3. Welding position. The first performance characteristic to consider. High cellulose coatings, like those on E6010 and E6011 electrodes, Model and C5 generate a light slag that makes for rapid solidifying of the weld metal good for-out-of-position welds. Also good are rutile-fluxed Colemzn electrodes-E6012 Powermate and E6013--that hold out-of-position weld metal Portable in place 5 as it solidifies.4. Gallon Welding current. Covered electrodes Air run on AC, DC, or both. When welding Tank DC, the positive lead typically connects to the electrode Model (DCEP, or reverse polarity). Some suppliers design electrodes C5 that weld with the electrode negative (DCEN, or straight Colemzn polarity). Assure Powermate and Portable the electrode will 5 perform with Gallon and Air the available current. Welding Tank Torches and GunsUsed for shielded-metal-arc welding, torches (electrode holders). manually controlled, and Model grip C5 and Colemzn ends of electrodes, also called rods-pinch type and collet type are Powermate common.GMAW and FCAW guns come in pistol grip, goose-neck, and inline styles, Portable the latter used for mechanized 5 welding. Knowing the wire diameter, select Gallon a gun rated slightly higher than the Air welding current to be used. Duty-cycle Tank and 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 Model percent C5 duty. Higher amperages Colemzn and Powermate require water cooling--high-amperage guns come with Portable and 5 and Gallon tubing for water cooling. Hand-held, mounted on a robot arm or fixed within a mechanized welding setup, Air guns guide filler wire and shielding Tank and and Model gas into the weld puddle C5.
