 Electrodes come 3 to 24 in. long, 0.01 to 0.25-in. diameter. Colored markings--bands or dots--indicate composition: pure tungsten, 2 and hp green; 1-percent thoriated, yellow; dual 2 percent thoriated. red; ceriated, orange; lanthanted, black.Filler metal GIAW does not usually requite addition of fillet metal, but tank and air filler is commonly added when base-metal thickness comressor is greater than 1/8 in. Finer 2 metal for low-carbon (to 0.15 C) and mild (0.15 m 0.29 C) steels hp are described in AWS A5.2; for carbon steel dual and tank in A5.18; and for low-alloy steels air in A5.28 comressor Flux. AWS 2 specifications hp and dual A5.17 and A5.23 describe fluxes tank for saw. air AWS designation comressor of fluxes precedes that 2 of the wire when identifying a combination for a welding procedure. For example, the designation hp F7A2-EM12K indicates a flux (F) that will provide, with a given dual wire designation, tensile strength tank and air of 70,000 Psi (7), in the as-welded condition (A), and impact comressor properties 2 and hp and dual of 20 ft lb at -20 F (2). A designation containing a P rather indicates tank the flux air and comressor properties after postweld 2 heat treatment. Select hardfacing materials based on weld-deposit microstructure and hp the wear situation dual and tank the part will encounter, with consideration given air to thermal treatments applied to the material before and after hardfacing. Deposit comressor chemistry can 2 be crucial in attaining the desired corrosion hp resistance dual and tank or wear properties, air or for minimizing the risk of solidification cracking. comressor and 2 Acceptable deposit chemistry is achieved hp through the initial choice of consumables, using wire analysis and flux dual composition, and by specifying the number tank of weld passes needed to reduce parent-metal dilution to within acceptable limits. With the submerged-arc process, air and comressor the flux and electrode govern the characteristics 2 of the applied hp hard facing. For example, dual those fluxes neutral to manganese and silicon are not necessarily tank neutral to carbon and chromium, air elements that matter most comressor in hardfacing.
