Is AA 203.0 casting weldable?
Is AA 203.0 casting weldable?
(OP)
Is Aluminum Association 203.0 (AA 203.0)casting weldable? Where can I get the specs? SAE? or AMS? or MIL? If it is weldable, what is weld wire? or the weld spec? Where can I get buy the wires? in the USA or Overseas?
Thanks for your help.

RE: Is AA 203.0 casting weldable?
I would suggest that you attempt to qualify a weld procedure using 2319 or 4145 filler metal with the GTAW process. A good guideline for weld procedure qualification is ASME Boiler and Pressure Vessel Code, Section IX.
I can't guarantee that you will not have a hot cracking problem with AA 203. In general, the information that I have read indicates that a copper content of about 3% or less in this alloy is more susceptible to hot cracking in comparison to alloys containing slightly higher copper contents - like AA203.0 (4.5-5.5% Cu)
Weld filler metal SFA 5.10 ER or R 2319 or ER or R4145 can be purchased in the US.
