Hi Been learning Al-GMAW, as seen in other posts. Testing the quality of the weld...
With steel welds, if you mess it up, the loss of properties is toughness not strength (in the main, to an approximation) - and toughness is expensive and difficult to measure, especially for a weld.
From what I read about Al, if you mess-up your weld conditions, the loss of properties will be strength - and that is easy and cheap to measure - eg. my home-spun test for fillet-welds (video on my website)
Is that right?? Can you measure / verify you have kept your weld on the optimum with a tensile test, for Al welds welding Al plate?
Thanks in advance... Rich S
