Abstract
A welding machine lays down its welding bead at the juncture of two surfaces, back of which a pressure boundary has been formed. A depression, or groove, is provided at the juncture of the two surfaces. The weld bead bridges over the groove to form a junction of the two surfaces, leaving the bottom of the groove above the pressure boundary to function as a passage for materials at the surfaces which vaporize at the temperature of the welding operation. The escape of the gases through the passage obviates the gases bubbling up through, and deteriorating, the solidifying weld material forming the junction.
