WERKWIJZE VOOR HET GEVEN VAN EEN WARMTEBEHANDELING AAN METAAL. |
摘要 |
<p>A method of relieving stress in microstructure welds and in the heat- affected zone in the adjacent base metal in low alloy steel, comprises induction heating in a second post-weld heat treatment. The heated area is monitored with a radiation pyrometer to ensure precise temperature control of the procedure. The method is particularly applicable to the heat treatment of selected small areas of a metal article without heating the whole article.</p> |
