Hold Gun and Control Gun Trigger Workpiece...
6-4. Conditions That Affect Weld Bead Shape NOTE 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. ° Push ° Perpendicular Drag GUN ANGLES AND WELD BEAD PROFILES Short Normal Long...
6-5. Gun Movement During Welding NOTE Normally, a single stringer bead is satisfactory for most narrow groove weld joints; however, for wide groove weld joints or bridging across gaps, a weave bead or multiple stringer beads works better. Stringer Bead – Steady Movement Along Seam Weave Bead –...
6-8. Troubleshooting – 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. Voltage too high. Select lower voltage range. Electrode extension (stickout) too long.
6-10. Troubleshooting – Excessive Penetration Excessive Penetration – weld metal melting through base metal and hanging underneath weld. Excessive Penetration Good Penetration S-0639 Possible Causes Corrective Actions Excessive heat input. Select lower voltage range and reduce wire feed speed. Increase travel speed. 6-11.
6-13. Troubleshooting – Burn-Through Burn-Through – weld metal melting completely through base metal resulting in holes where no metal remains. S-0640 Possible Causes Corrective Actions Excessive heat input. Select lower voltage range and reduce wire feed speed. Increase and/or maintain steady travel speed. 6-14.
