PJC-Sulphur Springs Workforce Center welding instructor John Plemons, center, shows student Logan Lair, left, and Sean Sartin the procedure for testing weld quality and strengths on the coupon bender. The coupon bender puts pressure on these pre-cut pieces of metal, roughly the shape of a coupon, to test the quality and soundness of the student’s weld. Plemons said the coupon welds are tested to AWS codes D.1.1 and ASME.
