Key Engineering Features
Purged TIG Welding
Argon backing gas and purging chambers are used during welding of reactive metals like Titanium to prevent atmospheric contamination.
Duplex Phase Balance Sizing
Careful temperature monitoring and heat input control during welding ensure a correct 50-50 ferrite-austenite phase balance in Duplex materials.
Certified Welders
Our welders are certified to ASME Section IX codes for pressure vessel welding, with regular radiography testing of weld seams.
