OM-235 281 Page 34 6-4. Conditions That Affect Weld Bead Shape . Weld bead shape depends on gun angle, direction of travel, electrode extension (stickout), travel speed, thickness of base metal, wire feed speed (weld current), and voltage.
OM-235 281 Page 35 6-5. Gun Movement During Welding . Normally , a single stringer bead is satisfactory for most narrow groove weld joints; however , for wide groove weld joints or bridging acros s gaps, a weave bead or multiple stringer beads works better .
OM-235 281 Page 36 6-8. T roubleshooting − Excessive Spatter Excessive Spatter − scattering of molten metal particles that cool to solid form near weld bead. S-0636 Possible Causes Corrective Actions Wire feed speed too high. Select lower wire feed speed.
OM-235 281 Page 37 6-1 1. T roubleshooting − Lack Of Penetration Lack Of Penetration − shallow fusion between weld metal and base metal. Lack of Penetration Good Penetration S-0638 Possible Causes Corrective Actions Improper joint preparation. Material too thick.
OM-235 281 Page 38 6-14. T roubleshooting − W aviness Of Bead W aviness Of Bead − weld metal that is not parallel and does not cover joint formed by base metal. S-0641 Possible Causes Corrective Actions W elding wire extends too far out of nozzle.
OM-235 281 Page 39 6-16. Common MIG Shielding Gases This is a general chart for common gases and where they are used. Many different combinations (mixtures) of shielding gases have been developed over the years. The most commonly used shielding gases are listed in the following table.
OM-235 281 Page 40 Problem Remedy Probable Cause W elding arc not stable. Wire slipping in drive rolls. Adjust pressure setting on wire feed rolls. Replace worn drive rolls if necessary . W rong size gun liner or contact tip. Match liner and contact tip to wire size and type.
