Oxide Free Titanium Welds with the PurgEye® Desk

The Welding Institute states that “Titanium is a reactive metal; it will burn in pure oxygen at 600°C and in nitrogen at around 800°C. Oxygen and nitrogen will also diffuse into titanium at temperatures above 400°C raising the tensile strength but embrittling the metal. Despite this reactivity tita ...

Secondary Inert Shielding Gas Application with Weld Trailing Shields

A secondary inert shielding gas application is often required when welding reactive metals such as titanium alloys and stainless steels, to protect the weld from oxidation until it has cooled to a safe temperature.  The low cost Argweld® Weld Trailing Shield® provides additional inert gas coverage ...

Weld Purging: Replace Foam with Film for High Quality Welds

The use of home made sponge foam purge dams for pipe weld purging is still very familiar throughout the welding industry. However, operators are unaware as to how the use of sponge foam can adversely influence the metallurgical strength of a joint. When sponge foam starts to warm up from the heat ...
