5. 定义Definition 5.1 预热 Preheating

焊接开始前，对焊件的全部或局部进行加热的一种焊接热处理工艺。

It is a kind of welding heat treatment process to implement the heating for the local/ integral weldment before welding.

5.2焊后热处理Post-welding heat treatment

焊接工作完成后，将焊件加热到一定温度，保温一定时间，使焊件缓慢的冷却下来，以改善焊接接头的金相组织和性能或消除残余应力的一种焊接热处理工艺。

It is a kind of welding heat treatment process to heat the weldment to a certain temperature and keep a certain time after the welding, then gradually cool down, in order to improve the metallurgical structure and performance of welding joint or eliminate residual stress. 5.3 热矫直Heat Straightening

通过加热使挠曲的板料、型材和管料变为平直状态的塑性加工方法。

It is a kind of plasticity processing method to make the bent plate material, profile material and pipe material to be flat through heating. 5.4弯管热处理Pipe bending heat treatment

管道弯曲后按一定热处理工艺进行局部或整管的热处理。

It is the local/integral heat treatment for the pipe in accordance with a certain heat treatment process after bending the pipe.
