Abstract
A rupture disc device and method of assembly thereof are provided. The rupture disc device has a device body formed so that there are no leakage pathways to the radially outer surface thereof. The rupture disc is welded to the device body so that the weld joint therebetween is not relied upon to provide structural support, and instead strictly acts as a seal. In one form, the weld joint is formed with the weld beam directed axially transverse to thickness of the rupture disc to minimize unwanted variances in the rupture disc burst pressure that otherwise may be created due to the heat generated during weld joint formation.
