Heat treatment

MarineShaft carries out heat treatment of steel and welded joints at our workshop in Hirtshals or on-site at your choice. Our mobile equipment enables our competent team to react swiftly wherever and whenever it is needed.

• Preheat
• Annealing
• Tempering
• Normalizing
• Calibration

The thermal stress from welding influences the material in the welded joint as well as in the surrounding areas. We carry out controlled heat treatment before, during and after welding and thereby eliminate any unwanted changes in the structure and properties of the material. Our heat treatment is carried out by certified technicians and in accordance with approved procedures.
