Armor Plate - Welding. Adaptability of Four Procedures for Welding Pistol Port Splash Beads
Abstract
The procedure employing a manganese modified 18-8 stainless steel electrode in all passes was completely satisfactory. The procedure employing a manganese modified 18-8 stainless steel electrode for the three buttering passes followed by reversed polarity mild steel deposits formed cracks in the mild steel beads adjacent to the buttering passes. The procedure employing a bare mild steel electrode for the three buttering passes formed porosity in the first three weld beads, but no cracking was observed in the heat affected zones or the weld metal. The procedure employing reversed polarity mild steel electrodes throughout was unsatisfactory since cracks were formed in the base metal heat affected zones. Some of these cracks formed perpendicular to the line of fusion, an extremely undesirable condition in armor plate.
