4.06 TIG (GTAW) Welding Problems<br />
FAULT CAUSE REMEDY<br />
1 Excessive bead build up or<br />
poor penetration or poor<br />
fusion at edges of weld.<br />
2 Weld bead too wide and<br />
flat or undercut at edges<br />
of weld or excessive burn<br />
through.<br />
3 Weld bead too small or<br />
insufficient penetration or<br />
ripples in bead are widely<br />
spaced apart.<br />
4 Weld bead too wide or<br />
excessive bead build up or<br />
excessive penetration in<br />
butt joint.<br />
5 Uneven leg length in fillet<br />
joint<br />
6 Electrode melts or oxidises<br />
when an arc is struck.<br />
Welding current is too<br />
low<br />
Welding current is too<br />
high<br />
Increase weld current and/or faulty joint<br />
preparation.<br />
Decrease weld current.<br />
Travel speed too fast Reduce travel speed.<br />
Travel speed too slow Increase travel speed.<br />
Wrong placement of<br />
filler rod<br />
A Torch lead connected<br />
to positive welding<br />
terminal.<br />
B No gas flowing to welding<br />
region.<br />
C Torch is clogged with<br />
dust or dirt.<br />
Re-position filler rod.<br />
A Connect torch lead to negative welding<br />
terminal.<br />
B Check the gas lines for kinks or breaks<br />
and gas cylinder contents.<br />
C Clean torch.<br />
D Gas hose is cut. D Replace gas hose.<br />
E Gas passage contains<br />
impurities.<br />
F Gas regulator turned<br />
off.<br />
G Torch valve is turned<br />
off.<br />
H The electrode is too<br />
small for the welding<br />
current.<br />
I Power source is set for<br />
MIG welding.<br />
E Disconnect gas hose from the rear of<br />
Power Source then raise gas pressure<br />
and blow out impurities.<br />
F Turn on.<br />
G Turn on.<br />
H Increase electrode diameter or reduce the<br />
welding current.<br />
I Set Power Source to LIFT TIG mode.<br />
