焊脚是焊接中角焊缝的横截面中，从一个直角面上的焊趾到另一个直角面表面的最小距离
本件全部焊接，焊后整形。未注明的焊脚高度为，修光去毛刺。
This part is made by welding and correct the defromation after welding. Unspecified weld leg is----. Grind to free of burr.
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.
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.
