ABSTRACT:
A fabricated pressure vessel having a heat fusible safety plug. The vessel is made of two or more shell member metalurgically joined together such as by furnace brazing in a protective atmosphere. One of the shell members has a conically shaped well which converges in an inwardly direction and terminates with a small aperture. A lead or other low melting point metal pellet is placed in the well and fused to the well surface during furnace brazing at a temperature greater than twice the melting point temperature of the fusible plug metal.
