We have significantly equipment for heat treatment in connection with welding, as well two stationary ovens as portable equipment for annealing. This is based on convection heating with electric heaters, and our control unit can be fully automatic, with controlled heating and cooling rate, using 6 channels simultaneously.
The temperature is measured with thermocouples on the item, and detected and documented by a potentiometer writer on the big oven and digitally on the smaller oven.
With our equipment, we can offer both preheating during welding as well as annealing of items after welding.
We have experience from assignments ranging from small to large pipes for complex item with a mass weight of several tons, and materials from plain carbon steel to high-alloy steel boiler (e.g. 12% Cr-steel).
