Various tests oh the inert-gas metal-arc welding of a corrosion resisting aluminum-magnesium-manganese alloy "ANP", have been performed with ANP-O and ANP-1/4H plates, 1/4 in. in thickness, and various consumable electrode wires, 2S, 52S, A54S, 56S and ANP. The tests consisted of, (1) effect of welding condition on penetration and bead shape, (2) influence of surface treatment, welding condition and technique on occurence of black powder arround bead and porosities in weld metal, (3) cracking properties versus filler wires, (4) mechanical properties of butt welded joint, (5) ductility and mode of fracture in tensile test, (6) hardness distribution and weld thermal cycle in welded joint, (7) effect of weld porosities on mechanical properties of butt joint, (8) microstructure, and (9) corrosion of welded joint. The present report Part 1 includes the tests (1) and a half of (2). The penetration characteristics, electrode melting rate and the effects of welding conbitions, filler wires, surface treatments, and torch angle on the occurence of black powder are discussed.
