A Comparison of Hydrogen/Oxygen and Natural Gas/Oxygen Torch Soldering Techniques

The tensile strength of connectors joining bars of palladium-silver alloy and formed using hydrogen/oxygen flame soldering was compared to those formed using conventional gas/oxygen soldering. As-cast specimens served as the control. No significant differences were found between the as-cast, hydrogen/oxygen flame soldered, or the natural gas/oxygen flame soldered specimens.
