A technique is taught for making a lap penetration weldment including a weld bead joining a first component to a second component, the first component overlying the second component, the weld bead penetrating through the first component and into the second component, the first component including a short overlapping portion between a centerline of the weld bead and an edge of the first component. Prior to forming the weld bead, the method includes applying to the short overlapping portion of the first component at least one normal force directed toward the second component, and applying to the short overlapping portion at least one tangential force directed toward the weld bead, the tangential force(s) preventing formation of cracks along a boundary of the weld bead, a fusion zone of the weld bead, or a heat affected zone of the weldment. |
