 Electrodes come 3 to 24 in. long, 0.01 to 0.25-in. diameter. Colored markings--bands or dots--indicate composition: pure tungsten, green; conpressor and air 1-percent thoriated, yellow; 2 percent thoriated. red; ceriated, orange; lanthanted, black.Filler metal GIAW does not usually requite addition of fillet metal, tank but filler is commonly added when base-metal thickness is greater than 1/8 in. Finer metal for low-carbon (to 0.15 C) and mild (0.15 m 0.29 C) steels are described conpressor and air in AWS A5.2; for tank carbon steel in A5.18; conpressor and air for low-alloy steels in A5.28 Flux. AWS tank specifications A5.17 and A5.23 describe conpressor fluxes air for saw. AWS designation of fluxes precedes that of the wire when identifying a combination for a welding procedure. For example, the designation F7A2-EM12K indicates a flux (F) that will provide, with tank a given wire designation, tensile strength of 70,000 Psi (7), in the as-welded condition (A), and impact conpressor properties of 20 ft lb at air -20 F (2). A designation containing a P rather indicates the flux tank properties after postweld heat treatment. 1. Mechanical properties of the base material. Tensile strength and yield strength conpressor of the weld metal should equal or exceed that of the base material. Ductility and toughness air at low temperatures may also be tank important. High-temperature service requires conpressor resistance to creep. Shock air loading requires impact resistance. In general, weld metal tank should match base-material properties.2. Composition of the base material.For stainless steels, low alloy steels, nickel and copper alloys, and materials that serve in corrosive atmospheres, chemical conpressor and air composition is important. tank and conpressor Consider the possibility air of electrochemical corrosion between base and weld metal of different compositions tank.
