- Page 33 9-8. 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.
- Page 34 9-11. Troubleshooting − 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. Joint preparation and design must provide access to bottom of groove while maintaining proper welding wire extension and arc characteristics.
- Page 35 9-14. Troubleshooting − Waviness Of Bead Waviness Of Bead − weld metal that is not parallel and does not cover joint formed by base metal. S-0641 Possible Causes Corrective Actions Welding wire extends too far out of nozzle. Be sure welding wire extends not more than 1/2 in. (13 mm) beyond nozzle. Unsteady hand.
