Vaal Heat Treatment Services Sandblasting is a new service Vaal Heat Treatment has to offer to it's current customers as well as others requiring this service.
Weld Distortion Control prevents up to 90% of weld distortion and saves time during welding.
Welding can severely influence strengthened or hardened metals, depending on the hardening technique used. Because of this, post-weld heat treatment is often very helpful in maintaining weld joint strength.
Vibrate Stress Relieve removes thermal stress from a metal part. Thermal stress is caused by a sharp temperature drop in metal. It creates problems of distortion and premature cracking. "Stress relieving" reduces these effects.
Advantages of Weld Distortion Control : 1) Reduces Distortion during the welding process;
2) Saves time during the welding process;
3) Improves welding process;
4) Reduces Thermally induced stresses from welding immediately;
5) Easy to operate;

Welcome to Vaal Heat Treatment, company based in Vereeniging.

Heat treatment of steel and other suitable metals involves the heating of the items to specific temperatures where desired metallurgical changes to the microstructure takes place. These temperatures can range from as low as 250ᵒC to temper hardened steel to as high as 1150ᵒC on certain Tool Steels. The main purpose of Heat Treatment is to obtain the desired Hardness, Tensile Strength, Ductility, Internal Stress Levels and Microstructure in the steel. |

Weld Distortion Control – Vibrating a work item at the optimal vibration level during welding, helps reduce distortion and saves time. Stresses induced by welding, is immediately reduced by vibrating at optimal vibration level during welding. |
 |
Vibrate Stress Relief is a non-thermal stress relief method that employs tightly controlled, high force, mechanical vibration energy to redistribute internal stresses in castings, forgings, and welded structures, parts, and components. Vibratory stress relieving significantly reduces dimensional instability during machining, improves fatigue life, and minimizes distortion during assembly, test loading, transport, and field usage of a wide array of metal components. |
