Re: aluminum design

[Subject Prev][Subject Next][Thread Prev][Thread Next]
Please note Mr. Wright's cautions. I work with structural aluminum from an
inspection/testing perspective on aregular basis. Process control is
critical regarding fabrication practices. A poorly welded aluminum joint may
lose up to 60% (or more!) of the base metal properties if not executed
properly. Good luck.
