Welcome
At Applied Welding Technology (AWT), we are committed to providing our clients with innovative solutions for their most challenging pressure part and mechanical part repair requirements.
Since our establishment in 1987, AWT has grown from a small 12-man operation with a steel yacht in the workshop to a fully integrated facility offering comprehensive welding, machining, fabrication, and testing services.
Located in Spartan, Kempton Park, our facility benefits from a strategic network of subcontractors with specialized capabilities not readily available in-house.
What We Do
With a primary focus on welding and machining critical parts, AWT excels in working with a wide range of materials. Our expertise extends to rebuilding with base materials and cladding surfaces using Stellite, Inconel, Bronze, Stainless steel, Monel, and more.
Whether it’s handling items as large as 10 tons or working with nozzles featuring 32mm bores, we leverage our in-house machining and heat treatment capabilities to deliver comprehensive solutions.
AWT specializes in the full spectrum of power station and petrochemical materials.
Quality control and assurance are fundamental to our processes. We diligently monitor every step and conduct industry-standard tests at necessary intervals, accompanied by meticulous documentation, ensuring the highest standards of excellence.
