I-CAR · December 3, 2018
Summary
This article emphasizes the critical importance of performing destructive weld testing on scrap metal of the same type and thickness before welding on a vehicle. It explains that visual inspection and destructive testing (tearing and twisting) ensure welder settings and technician techniques are correct to guarantee a quality, safe repair.
What to do on the job
Perform visual inspection and destructive testing (tearing and twisting) on scrap metal of the same type and thickness as the vehicle before performing any actual vehicle welding.
How to use it
