Filler 1

[greencircle]

Want to weld Alum 7046 (Extruded pole ) to Alum 356 ( Cast base). What filler material should we use?

Can some one please guide me to a good resource/article on this.

Most filler metal suppliers have extensive charts with (about) all possible alu combinations, and the different recommended types of filler to be used.
ESAB does for sure,
Most likely, the Lincoln company will also have this published ont heir website.
