具有不大于焊脚尺寸的小开口焊缝，其所能承受的扭矩与相应闭合角焊缝所能承受的扭矩是几乎相同的。
Value of torsion for less than the size of fillet weld height of small-opening fillet weld is the same as that of corresponding closed fillet weld.
分析了强度匹配对角焊缝设计的影响，建立了角焊缝焊脚尺寸与板厚，强度匹配系数之间的关系，讨论了强度匹配选择的依据。
The influences of strength matching on fillet weld were analyzed. The relationships among fillet weld size, thickness of base metal and matching coefficient of strength were established.
按目前大多数人认可的角接接头焊脚的定义，根据DL/T869—2004《火力发电厂焊接技术规程》去控制焊接尺寸，会出现焊缝有效厚度不足的问题。
The weld size was controlled according to the definition of leg on the corner joint and DL/T869—2004 (power plant welding technical regulation), which led to the effective thickness was insufficient.
厚板焊接结构的角焊缝，多数情况下没必要完全焊透，但是，如果未焊透部分尺寸过大，就会使焊接接头的疲劳强度大幅度降低。
There is no need to weld the joint thoroughly for the cruciform joint. But if the dimension which is not welded is too large. that will make fatigue strength reduce.
焊缝尺寸 （如对接焊缝的焊缝宽度、角焊缝的焊角尺寸等 ）是表示焊缝形状特征的指标 ，是影响焊缝质量的重要因素之一。
Weld-shape(butt weld width, size of fillet weld)is an indicator of weld features and it also is an important factor of quality welding.
角焊缝的强度不仅与焊脚尺寸有关，还取决于焊缝金属与母材强度的匹配。
The strength of fillet welding joint is related not only to the fillet weld size, but also depends on the base metal strength matching.
角焊缝的强度不仅与焊脚尺寸有关，还取决于焊缝金属与母材强度的匹配。
The strength of fillet welding joint is related not only to the fillet weld size, but also depends on the base metal strength matching.
