SAFETY SERVICEBASIC WELDING WELDING TIPSSETUP
A good way to test welding technique is
to examine a weld’s appearance after it has
cooled and the slag has been removed. Then,
better welding can be learned by adjusting your
weld technique to remedy any problems found.
Cleaning the Weld
TO PREVENT
SERIOUS INJURY:
Continue to wear ANSI-approved
safety goggles and protective
wear when cleaning a weld.
Sparks or chips may y when
cleaning.

separately) to shape the weld.
STRIKE TEST
A test weld on a PIECE OF SCRAP can be tested by
using the following procedure.
WEAR ANSI 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.
After two scraps have been welded 1.
together and the weld has cooled, clamp
one scrap in a sturdy vise.
Stay clear from underneath while you 2.
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.
