Abstract:The measurement of welding thermal cycle curve has always been the main way to study the quality of welded joints. The quality of the curve itself directly affects the further study of the organization. consequently, in this paper, the advantages of several welding thermal cycle measurement methods are summarized, and the development direction of welding thermal cycle measurement in the future is prospected based on the above two methods.

Key words:Welding thermal cycle; HAZ; Direct measurement method; Indirect measurement method;

1 引言

焊接热循环包括以下四个特征参数:加热速度(ωH)、最高加热温度Tmax在相变温度以上停留时间(tH)、冷却速度(ωC)和冷却时间(t8/5、t8/3、t100)。(剩余5240字)
