• Lower sensitivity to wind <strong>and</strong> drafts than gas shielded welding processes<br />
• All position capability<br />
Common Stick Welding Problems are:<br />
• Arc Blow<br />
• Arc Stability<br />
• Excessive spatter<br />
• Incorrect weld profile<br />
• Rough surface<br />
• Porosity<br />
Submerged Arc Welding<br />
Submerged arc welding (SAW) is a high quality, very high deposition rate welding<br />
process. Submerged arc welding is a high deposition rate welding process<br />
commonly used to join plate. Submerged Arc Welding Benefits are:<br />
• Extremely high deposition rates possible<br />
• High quality welds<br />
• Easily automated<br />
• Low operator skill required<br />
Common Submerged Arc Welding Problems are:<br />
• Solidification Cracking<br />
• Hydrogen Cracking<br />
• Incomplete fusion<br />
• Irregular wire feed<br />
• Porosity<br />
