Global Stainless is applying controlled atmosphere welding techniques to support fabrication of titanium and other specialist materials for aerospace and high-performance applications.
The company operates an argon purge chamber, effectively creating a sealed environment where oxygen levels can be tightly controlled during the welding process. This approach is used when working with reactive materials where contamination can affect weld integrity.
Former company director Lincoln Raikes says maintaining a controlled environment is critical.
“Total Oxygen depletion and control of the argon level is absolutely essential when welding these very expensive materials as any rise in Oxygen can destroy the quality of the weld,” says Raikes.
The chamber allows welding to be carried out within a stable atmosphere, with oxygen levels monitored and managed throughout the process. The company has invested in an oxygen measurement system capable of detecting concentrations down to 5ppm, supporting applications where extremely low oxygen levels are required.
“We are welding ultra-high temperature resistant metals in as low as 10ppm of Oxygen, so it is an extremely controlled atmospheric process,” Raikes says.
Controlled atmosphere welding is commonly used in aerospace and related industries where material performance and reliability are critical, particularly when working with titanium and other reactive alloys that are sensitive to oxidation.
Alongside its welding capability, Global Stainless also undertakes fabrication of stainless steel components, including spherical forms, domes and long radius bends. The company produces stainless steel spheres for specialised applications, as well as long radius bends up to 6-inch diameter.
These capabilities support a range of industrial and specialist projects, with the controlled welding environment forming part of the company’s broader fabrication offering.
