TiG Welding of Titanium Alloys

MSM aerospace fabricators is a proven specialist in welding high temperature, heat resistant titanium alloys as used in the aerospace industry. Having a team of coded welders with over 100 years of combined experience, MSM is capable of producing the most complex parts and assemblies.

The example shown in this photograph is a potable water tank as used in a business jet application. With a capacity of 26 gallons and an overall size of 1m x 0.5m x 0.225m the assembly consists of a total of nine internal baffles. This complex assembly uses 1.2mm thick TA10 for the outer walls and 1.6mm thick TA10 for the internal features. Besides the limited access, one of the important aspects is that the welder must have a high degree of skill in order to avoid any oxidisation of the welded joints. MSM’s team of coded welders achieves this by manually TiG welding using argon purged protective backing, all within a total manufacturing time of less than 80hours.

MSM’s NADCAP approved welding facility consists of a team of highly experienced coded welders working in accordance with the AWS D17 Specification for Fusion Welding in Aerospace. Fusion welding is performed using equipment incorporating the very latest advanced inverter technology. Also included within the facility are Jetline and Hobart semi-automatic Seam welding machines and Siacky Spot welding equipment. This highly efficient facility is supported by MSM’s NADCAP approved NDT PFD dye penetrant inspection facility with X-ray requirements being sub-contracted to reputable aerospace approved 3rd parties.

MSM’s fusion welding manufacturing capability covers a wide range of cylindrical and prismatic component parts including connectors, reducers, gimbals, pipes, filters, ozone converters and manifolds as used in aircraft engine bleed air applications, fuel systems and other aircraft ECS (environmental control systems); small to medium sized assemblies such as potable water tanks, fuel tanks and hydraulic reservoirs and heat exchangers; larger assemblies including ATR exhausts, engine nacelles and turbine compression ring assemblies.
