A series of tests was conducted to establish optimum procedures for TIG welding and heat treating of AM350 and AM355 steel sheet in thicknesses ranging from 0.010 inch to 0.125 inch. Statistical analysis of the test data was performed to determine the anticipated minimum strength of the welded joints

Welding of AM350 and AM355 Steel 
A series of tests was conducted to establish op-
timum procedures for TIG welding and heat treating 
of AM350 and AM355 steel sheet in thicknesses rang-
ing from 0.010 inch to 0.125 inch. Statistical analy-
sis of the test data was performed to determine the 
"anticipated minimum strength" of the welded joints.
