1. Scope This standard specifies the carbon steel and low alloy steel after welding heat treatment method (hereinafter referred to as heat treatment method). 2. After the types of post-heat treatment methods of post-heat treatment, furnace heating and heat treatment after the partial heat treatment of two ways. 3 furnace heat treatment method 3.1 heating device This standard does not specify the type of heating furnace and its form, but the heating device must meet the 3.2 requirements. 3.2 after the heat treatment method after the heat treatment method is as follows: (1) after the heat treatment, the object should be heated in principle, heating furnace. Can not be a furnace, can be divided into two or more into the furnace, but this time, repeated heating part must be
