TiG Welding of Aluminium Alloys

TiG Welding of Aluminium Alloys

MSM aerospace fabricators is a proven specialist in welding the full range of aluminium alloys as used in the aerospace industry. Having a team of coded welders with over 100 years of combined experience MSM has the capability of producing the most complex parts and assemblies.

The example shown in this photograph is an exhaust plenum diffuser as used on the Falcon 7X business jet. With overall dimensions of 0.4m and diameters tapering from 240mm to 159mm, the mesh cage is cut and rolled prior to manually fusion welding to form the cone, the cylinder and then to the two end flanges. The perforated mesh is 1mm thick L113-T4 aluminium requiring a high degree of skill and dexterity to manually weld avoiding blow holes and distortion.

MSM’s NADCAP approved welding facility consists of a team of highly experienced coded welders working in accordance with the AWS D17Specification 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 issupported by MSM’s NADCAP approved NDT PFD dye penetrant inspection facility with X-ray requirements being sub-contracted to reputable aerospace approved 3rdparties.

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.
