Reducing partial rigidity: When closedweld or the weld which has less rigidity are welded, we can take anti-deformation way to reduce the partial rigidity of component.
降低局部刚性：焊接封闭焊缝或其刚性较大的焊缝时，可以采取反变形法来降低结构的局部刚性。

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.
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。

Leaving the disc in a fully closed position firmly closed also prevents weld spatter from falling directly onto the mating faces of the seat and disc.
