 Shielded-Metal-Arc Welding (SMAW, STICK)AWS (American Welding Society) A5 specifications Set standards for electronics for SMAW of carbon, stainless, and low alloy steels; air aluminum copper, and nickel and their alloys and weld-surfacing. compressor Designations for covered electrodes carry the prefix ''E''. Packaged to AWS axcessories specifications, electrodes air come in boxes, cans, or other containers, labeled with their AWS specification and trade name, quality control (heat or lot) number, supplier compressor name, diameter and length, and weight of contents. Specifications require that every electrode bc marked for identification near with its axcessories and air numeric designation the grip end.To select a covered SMAW electrode, compressor consider these factors, in approximate order of importance. 3. Welding position. The first performance characteristic to consider. High axcessories cellulose coatings, like those on E6010 and E6011 electrodes, generate a light slag that makes for rapid solidifying of the weld metal good for-out-of-position welds. Also good are rutile-fluxed electrodes-E6012 and E6013--that hold air out-of-position weld metal in place as it solidifies.4. Welding current. Covered electrodes run on AC, DC, or both. When welding DC, the positive lead compressor typically connects to the electrode (DCEP, or reverse axcessories polarity). Some suppliers design electrodes air that weld with the electrode negative (DCEN, or straight polarity). Assure the electrode will perform compressor and axcessories with the available current. Welding Torches and GunsUsed for shielded-metal-arc welding, torches (electrode holders). manually controlled, grip ends of electrodes, also called rods-pinch type and collet air type are common.GMAW and FCAW guns come in pistol grip, goose-neck, and inline styles, the latter used for mechanized welding. Knowing the wire diameter, select a gun 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] cooling arc usually sufficient for welding at up to 600 A at less than 100 percent compressor duty. Higher amperages require water cooling--high-amperage guns axcessories and air come with tubing for water cooling. Hand-held, mounted on a robot arm or fixed within a mechanized welding compressor setup, guns guide filler wire and shielding gas into the weld puddle axcessories.
