The Pipe Material Is Investigated Further And Now The Welds Are Inspected External Inspection Of The Welds Shows That W 1 (151.91 KiB) Viewed 34 times

The pipe material is investigated further and now the welds are inspected. External inspection of the welds shows that welding was done correctly. The engineers also want to see the influence (if any) of the welding procedure on the microstructure. They do a number of tests with three different test materials: Al 1: Undeformed, pure aluminium, Al_2: Cold deformed, pure aluminium, Al 3: Undeformed aluminium with some magnesium dissolved homogeneously. First investigations indicate good weldability for all materials. a) Is there a hardness difference between Al_1 and Al_2 in unwelded conditions? Please explain thoroughly.
