  • Articulated protective shield for a welding head
    Patent number: 5084603
    Abstract: A protective shield for a welding head is disclosed having an articulated construction to enable the shield to readily assume the contours of the parts to be welded or the contour of the weld bead. The shield is formed of shield members pivotally attached together and pivotally attached to the welding head. The protective shield also incorporates a locking device in each of the shield members that is activated by the pressurized protective gas directed onto the welded area. The pressurized gas urges pistons associated with each of the shield members against portions of an adjacent shield member to lock the members in their desired positions. The protective shield may be placed in its desired orientation by bringing it into contact with the parts to be welded such that the weight of the protective shield automatically causes it to assume the parts' contour. The application of the protective gas to the protective shield will automatically lock it in this position.
