    Which heat treatment is required after welding?

    Cooling from the stress relief temperature is controlled in order that no harmful thermal gradients can occur. A low temperature heat treatment carried out immediately on completion of welding by increasing the preheat by some 100°C and maintaining this temperature for 3 or 4 hours.
