LOCALIZED
HEAT
TREATMENTS

Localized Heat Treatment consists of a heating-holding-cooling thermal cycle carried out according to specific rules and parameters.

The heat is produced by a band made of electrical resistances applied directly onto the piece and powered by a dedicated low-voltage unit.

When the conditions for treating the piece in a furnace are not met, it is possible to isolate a specific area and propagate the heat with the aid of contact electrical resistances that transmit the heat to the area concerned.

A unit modulates the flow of electrical energy sent to the resistances and at the same time records the temperatures obtained.

ADVANTAGES

With this method it is possible to avoid dismantling components or parts that may be difficult to remove; moreover, welds carried out on site can also be treated.

DISADVANTAGES

It is a much more complex method than the furnace one, and the timing and feasibility are not always favourable.
