Page 4 - WELDING PROCEDURES; Procedures
-4- WELDING PROCEDURES Out-Of-Position Welding (Vertical and Overhead) When welding out-of-position, the molten metal tends to spill outof the joint. To offset this tendency, an electrode with a fastfreezing deposit is needed. Welding made with out-of-position electrodes is slow, relativelyexpensive...
