Applied Welding Technology was started in 1987. The company has steadily grown from the original welding shop to now integrate a machine shop with the welding operations. The location in Sebenza, near Edenvale, Johannesburg is ideally placed to access an extraordinary variety of subcontractors for capabilities not available in-house.

The business specializes in repairing turbine valve components and other high quality machined and welded items. Currently AWT does OEM turbine valve repairs for Alstom and MAN. It also has Eskom Level 1 welding approval, TuV Rheinland ISO 9001 approval and is a BBBEE level 3 rated company..

The business concentrates on specialised welding services, particularly in Stellite cladding and in rebuilding parts machined to high tolerances.

Wherever possible the welding is automated in a wide variety of manipulators. A recent example of this capability was the internal repair of Inconel 625 clad pipes 12m long in 12” and 14” sizes for BP destined for an Angolan oil project using remote TV cameras. At the other end of the scale AWT has internally clad nozzles as small as 25mm internal ID.

The variety of materials welded at AWT is remarkable for the diversity and we weld, on a daily basis, steels running through basic Carbon steels to X20CrMoV121, Stainless steels, Nickel alloys such as Inconel, Tin and Aluminium Bronze, Aluminium and Cast Iron.

The equipment at AWT consists of the following:

-     A divided shop totalling 1000m², with one side devoted to machining and heat treatment and the other to welding.

-     An 8 ton overhead crane in the welding shop.

-     A 3 ton overhead crane in the machine shop.

-     4 off TIG welding stations each equipped with 450A pulsed arc welding machines and rotators.

-     4/5 MIG welding stations equipped with a variety of rotators and Pulsed/Synergic welding machines.

-     1 SAW welding machine.

-     A library of welding procedures suitable for ASME and EN ISO coded welding on most power station and pressure vessel steels.

-     3 coded TIG welders and 3 coded MIG welders.

-     A heat  treatment furnace 1.5m long x 1.2m wide x 1.2m high capable of temperatures up to 1100°C

-     5 conventional lathes ranging up to a 4.5m long bed and a 800mm swing.

-     1 horizontal boring mill 1.2m swing by 660mm high.

-     2 CNC lathes, largest size 1.5m x 480mm swing.
