Localized Heat Treatment consists of a thermal cycle of heating-holding-cooling performed according to specific rules and parameters.
Heat is generated by a band composed of electrical resistances applied directly to the component and powered by a special low-voltage equipment.
Localized heat treatment equipment
Localized stress relieving heat treatment on nozzle
Localized heat treatment on weld
Heat treatment on boiler header welds
Localized heat treatment
If the piece is not treatable in the furnace, it’s possible to isolate a specific area and propagate the heat through electric heaters.
An equipment modulates the flow of electricity to be sent to the resistors and records the temperatures obtained.
ADVANTAGES
With this methodology it’s possible to avoid disassembly of components for which removal may present difficulties, and to treat welds while still in work.
DISADVANTAGES
It’s a much more complex method, and the timing and feasibility are not always favorable.
