Cutting test coupons
Posted: Thu Oct 08, 2009 6:04 am
The other day, I made a little mig aluminum coupon( I have been struggling), just 2 peices of flatbar put together to make a fillet weld. After I finished, I cut the coupon at the center of each weld with a portaband saw, and after inspection, I could see no cracks, holes or defects at all, which I know is not possible becuase I intentionally 2(out of 5) of the welds sucky. Perhaps the saw meshed the aluminum into the cracks and holes, anyone have a better method of cutting coupons(I dont have any of thaT powdery weld inspection stuff either)
