WELD EXAMPLES & TROUBLE SHOOTING

WELDING TIPS

• Smooth bead

• Minimal spatter

• Good fusion

• Stringy and lack of fusion

• Lack of fusion

• Excessive spatter

GOOD WELD

WELD SPEED TOO FAST

CURRENT TOO LOW

STICK OUT TOO LONG

• Melt through

• Too wide

• Bead to flat

CURRENT/WFS TOO HIGH

WELD SPEED TOO SLOW

• Stickout

1/2

”

+/-

1/8

”

• Short stickout = more

current and more

penetration

• Affects the arc shape

• Less voltage = tighter

arc and potentially

more spatter

OPTIMAL STICKOUT

THIN MATERIAL

THICK MATERIAL

Less voltage

More voltage

Lower wire feed speed

Higher wire feed speed

Faster travel speed

Slower travel speed

VOLTAGE

• Higher wire feed speed

equals more amperage

• Can also affect arc

shape and penetration

WIRE FEED SPEED

(WFS)

• Affects bead width

and height

• Can also affect

penetration

TRAVEL SPEED

1/2”
