Sheilding gases used are selected dependent on the aluminium grade to be joined.See all results for this questionWhat are unweldable aluminum alloys? - ESAB Welding & These alloys are usually heat treatable alloys and are most commonly found in the 2xxx series (Al-Cu) and 7xxx series (Al-Zn) groups of materials. In order to understand why some of these alloys are unsuitable for arc welding (unweldable), we need to consider the reasons why some aluminum alloys can be more susceptible to hot cracking.WeldingFor dissimilar metal joining of 556® alloy to nickel- or cobalt-base materials, 556® filler metal will generally be a good selection, but HASTELLOY® S alloy (AMS 5838) or HASTELLOY® W alloy (AMS 5786, 5787) welding products may be used. For dissimilar welding to iron-base materials, 556® filler metal is recommended.

DickersonWelding of Aluminum Alloys - Total MateriaIn general, the non-heat-treatable aluminum alloys can be welded with a filler alloy of the same basic composition as the base alloy. The heat-treatable aluminum alloys are somewhat more metallurgically complex and more sensitive to "hot short" cracking, which results from heat - affected zone (HAZ) liquidation during the welding operation.Welding aluminum piping - The FabricatorOct 11, 2005 · You can weld aluminum pipe joints using an open-root technique, but it's more difficult to do than it is with steel. Aluminum's high thermal conductivity means that the weld pool is larger than it is in steel. The weld pool also is more fluid, so it's harder to control the molten pool. Open-root welding almost always is performed using GTAW.
