WELDING TIPS
Hydrogen is welding enemy
Hydrogen is the worst weld-destroying impurity around. Because it is everywhere (in water, dirt, rust, paint, manure, grease), hydrogen is a huge challenge for welders. What can be done to gun down hydrogen? Clean, clean, and clean some more. “Hydrogen, along with high-residual stress and crack-sensitive steel, may result in cracking hours or days after welding,” says Lincoln Electric’s Hoes. “High-strength steels (commonly used on tillage implements), thick sections of metal, and restrained parts are more susceptible to hydrogen cracking.”
