Heat Treatment

Pre heat treatment

To prepare and accompany the welding process.

Post weld heat treatment (PWHT)

Reduction of internal stresses in the workpiece, among other things after the welding process

Soaking

Reduction or elimination of hydrogen embrittlement in the workpiece.

Normalizing

Establishing a uniform and fine-grained (rounded) microstructure.

trace heating

Heating of pipes with electric heating mats or cables to support the flow properties of the flow medium.

Dry out

Drying out of large spaces and equipment lined with refractory material.

Heat shrinking

Force-fit joining or joining of two workpieces according to the principle of thermal expansion.

Pre heat treatment

To accompany the welding process, we bring the material to the necessary temperature. For special steel alloys and application scenarios of the components to be welded, an accompanying, process-safe preheating is absolutely necessary.

Post weld heat treatment (PWHT)

To reduce the thermal stresses introduced by the welding process, we stress relieve the affected components. Stress-relief annealing restores the microstructural properties required for the use of the component and reduces the hardness values increased by the welding process.

Soaking

To eliminate hydrogen embrittlement in the component, we heat the components to 200°C-300°C in a controlled manner, keeping this temperature constant for several hours. Soaking is always used when the hydrogen is introduced during the welding process or also during electroplating damages the technical properties of the material and is to be removed again by the heat treatment.

Normalizing

Normalizing may be required for cast or forged steel parts or even welded structures in order to eliminate structural irregularities. The slow but controlled heating and the planned fast heating and cooling phases are supervised by our experienced personnel and carried out trouble-free by our high quality equipment used.

Trace heating

In the process industry, various media that are transported through raw pipes to further processing must be continuously kept at a certain temperature. With our process-safe equipment and experienced personnel, we ensure that no unwanted cooling and thus possible damage occurs.

Heat shrinking

Components that have to be brought together with a planned oversize fit during assembly are shrunk on by us. Through the controlled application of heat, the outer component (e.g. a gear wheel that must be placed on a shaft) is expanded by the heat and can thus be connected to the inner component. The cooling causes the applied component to shrink and thus sit press on the inner component. The principle can also be applied to the disassembly of the outer component.

Dry out

Whether combustion chambers, cast-in-place pipe joints or other refractory linings - controlled drying is essential for durability. We dry any components with our high-speed gas burners either directly individually or completely in the composite at the same time in the kiln.
