    Abstract: Oxygen is mixed with another gas to form an auxiliary gas that will permit a welding of zinc-plated steel sheets (3a and 3b) without producing blowholes. An oxygen (O.sub.2) gas cylinder (4a) is provided in addition to an argon (Ar) gas cylinder (4b), for forming the mixed auxiliary gas, and the argon gas and the oxygen gas are mixed in a mixer (6) before being supplied to a machining head (7) and jetted onto a machining spot (9) through a nozzle (8). The oxygen oxidizes the zinc of the zinc-plated steel sheets (3a and 3b) to produce zinc oxide and zinc peroxide, to thereby prevent evaporation and minimize spatters, and thus permits a laser welding with a minimum generation of blowholes.

    Abstract: A touch-up welding apparatus for welding such portions of a motorcar body which remain unwelded after the body has passed along a main welding portion of an assembly line. Plural welding gun magazines holding differing welding guns are disposed along side of a welding station into which the motorcar body is positioned. A framework surrounds the welding station and supports the main body of a welding robot which is movable laterally and longitudinally of the station. A turnable, swingable wrist portion is provided on a lower end of an upwardly and downwardly movable robot arm attached to the robot main body. The differing welding guns may be selectively attached to the wrist portion and moved about the motorcar body as desired to weld the remaining unwelded portions thereof.

    Abstract: An articulated joint of changing the direction of a light beam passing through the joint has an inlet for the incoming light beam, an outlet for the outgoing light beam, two turning mirrors and three precision bearing units associated with the turning mirrors for permitting rotation of the mirrors with a minimum amount of error of angular displacement of the redirected beam. An apparatus providing movement of at least a portion of a beam delivery system and directing an outlet beam to a desired location includes the articulated joint, a motion delivery device operatively associated with the joint and connecting means disposed between the joint and the motion delivery device. The connecting means are adapted to provide relative motion between an attachment of the connecting means to the joint and an attachment of the connecting means to the motion delivery device. The precision bearings are associated with the turning mirrors and the outlet so as to decouple the articulated joint from the axis of the actuator mechanism, such as, for example, a robot arm. The precision bearing units incorporate two tapered roller bearings opposed to each other. Each tapered roller bearing has an inner race and an outer race. A preload arrangement preloads the bearings by exerting a force on the inner races which tends to squeeze the inner races together and by exerting a force on the outer races which tends to push the inner races apart.

    Abstract: A method and apparatus for welding studs to a workpiece are provided. When the studs are welded to workpieces using a drawn-arc, stud welding technique, sometimes a coating of smut is deposited on the workpiece around the welded end of the stud. This coating detracts from the appearance of the stud and workpiece. Further, if the workpiece is to be covered with a coating material, the coating of smut must first be removed, resulting in an extra operation. It has been found that the coating of smut will not be deposited if, during the stud welding cycle, gas is directed toward the weld area in a swirling manner around the end of stud where the weld occurs.
