Excessive Spatter
Excessive Spatter
:
Scattering of molten metal particles that cool to solid form near weld bead
.
Possible Causes
Wire feed too high
Voltage too high
Electrode extension (stickout)too long
Workpiece dirty
Dirty Welding wire
Select lower wire feed speed
Select lower voltage range
Use shorter electrode extension (stickout)
Remove all grease
,
oil
,
moisture
,
rust
paint
un-
dercoating
,
and
dirt
from
surface
before
welding
.
Insufficient shielding gas at welding arc.
