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 welding 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 fly when cleaning.

1. A weld from flux-core wire will be covered by slag.

Use a Chipping Hammer to knock this off.

Be careful not to damage the

weld or base material.

2. Then, use a Wire Brush to further

clean the weld or use an angle grinder

(sold 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-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.
