A test weld on a PIECE OF SCRAP can be
tested by using the following procedure.
WEAR ANSI-APPROVED SAFETY GOGGLES
DURING THIS PROCEDURE.
WARNING! This test WILL damage the weld it is
performed on. This test is ONLY an indicator of weld
technique and is not intended to test working welds.
1. After two scraps have been welded together and the
weld has cooled, clamp one scrap in a sturdy vise.
2. Stay clear from underneath while you strike
the opposite scrap with a heavy hammer,
preferably a dead-blow hammer.
3. A GOOD WELD will deform but not break, as shown
on top.
A POOR WELD will be brittle and snap at the
weld, as shown on bottom.
