Thermal cycling is an important factor to determine structure and property of HAZ after welding.───热影响区的热循环是决定焊后热影响区组织和性能的重要因素。
The microstructure evolution in HAZ of Welds is a complex procedure, which associates with many factors.───热影响区微观结构演化与诸多因素密切相关，是一个复杂的过程。
toughness of HAZ is higher than base metal under appropriate laser welding conditions.───合适的激光焊接条件下，热影响区韧性高于母材；
The results show that the welding thermal-cycle on its mechanical property of the HAZ has no evidence effect.───结果表明，焊接热循环对其热影响区的性能没有明显的影响；
The weld section looks like an inverted trapezia and the heat affect zone (HAZ) is very narrow.───焊缝截面呈上宽下窄的倒梯形，热影响区（HAZ）相当窄；
Fibrous processing marks remain in the heat-affected zone (HAZ) with part of precipitated solid phase solved into the base metal.───热影响区内，仍可见纤维状加工痕迹，部分析出相固溶到基体中；
The microstructure of weld bead obtained by shielded metal arc welding are massive ferrite and a little pearlite, HAZ are lath bainitic.───手工电弧焊焊缝组织主要为块状铁素体和少量珠光体，热影响区组织为板条状贝氏体组织；
The microhardness distribution of the welded joint is along the welding line. The microhardness is higher in nugget zone, and lowest in HAZ.───焊接接头的硬度分布沿焊缝中心基本对称，焊核区硬度较高，热影响区硬度最低。
