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.

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。

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.

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。
