TOO SLOW TRAVEL SPEED
A too slow travel speed produces a large weld with lack of penetration and
fusion. The energy from the arc dwells on top of the weld pool rather than
penetrating the base metal. This produces a wider weld bead with more
deposited weld metal per mm than is required resulting in a weld deposit of
poor quality.
CORRECT TRAVEL SPEED
The correct travel speed keeps the arc at the leading edge of the weld pool
allowing the base metal to melt sufficiently to create good penetration,
fusion and wetting out of the weld pool, producing a weld deposit of good
quality.
WIRE TYPES AND SIZES
Use the correct wire type for the base metal being welded. Use stainless steel or
silicon bronze wire for stainless steel, aluminum wires for aluminum and steel
wires for steel.
