摘要： The present invention pertains to: a method for arc spot welding a steel plate having a carbon equivalent CeqBM of 0.35 or more (the carbon equivalent CeqBM is defined in the specification) and containing 0.35 mass % or more of C, the method being characterized by forming a weld metal having a structure in which the proportion of an austenitic structure exceeds 80%; and a welding wire suitable for being used therefor. According to the arc spot welding method, brittle fracture can be prevented and high joint strength can be obtained even when the C content in the steel plate is high.

摘要： An arc spot welding method able to give a predetermined weld bead diameter or excess metal height in a back surface weld bead of arc spot welding and able to give a welded joint excellent in both strengths of TSS and CTS and a welding apparatus for working the same are provided. A steel sheet containing carbon in 0.2 mass % or more and having a sheet thickness “t” and at least one steel sheet containing carbon in 0.2 mass % or more and having a sheet thickness of “t” or more are arranged overlaid, a backing plate comprising a non-contact part and a contact part maintaining the back surface of the lower side steel sheet and the non-contact part in a non-contact state is arranged so that the contact part contacts the back surface of the lower side steel sheet at a position exceeding 3t from the circle equivalent center of the back surface weld bead, and arc generation and short-circuit conduction where the welding voltage between the welding wire and upper side steel sheet becomes 10V or less are alternately repeated so that the time period of the short-circuit conduction becomes over 30% to less than 60% per cycle to thereby weld the steel sheet.

摘要： An electric spot welding head for a multi-axis industrial robot that has a compact configuration, particularly in a longitudinal direction that goes from the end of the head for the attachment to the robot wrist towards the welding electrodes. This result is achieved primarily by the fact that the electrical transformer mounted on the head has its output connected to the electrode-holding arms arranged, respectively, on a front wall of the body of the transformer and on an end wall of the body of the transformer, for the connection to the electrode-holding arms of the head. The structure of the welding head is completely covered by a casing having a rear opening for connection to the robot wrist and a front opening from which the electrode arms of the welding head protrude.

摘要： A method for welding metal components to weld a first metal piece and a second metal piece to form a metal component comprises the steps of: positioning a first working portion of the first metal piece against a second working portion of the second metal piece to jointly form an intended welding seam; performing local welding on the intended welding seam to form a plurality of welding zones and a plurality of non-welding zones that are spaced from each other; providing a bonding paste to fill the non-welding zones and providing a curing condition to cure the bonding paste to mask the non-welding zones to finish welding of the first metal piece and the second metal piece to form the metal component.

摘要： Automatic welding machine includes: a welding torch mounted to a link actuation device set on a mount; and a one-or-more-axes linear motion actuator which causes the link actuation device to advance and retract relative to the mount. The link actuation device includes: a proximal end side link hub disposed on the mount; a distal end side link hub to which the welding torch is mounted; and three or more link mechanisms configured to couple the distal end side link hub to the proximal end side link hub. Each link mechanism includes proximal side and distal side end link members and an intermediate link member. Two or more link mechanisms are each provided with a posture changing actuator which arbitrarily changes the posture of the distal end side link hub relative to the proximal end side link hub.

摘要： A method of cutting out a part from a workpiece with making partially welded spots in wire electrical discharge machining to keep the part against falling apart away from the workpiece. There is no need to cut anew the welded spot left as in the conventional process. The cut-out parts are cut off at a time after breakage of the welded spots caused by an external impact. The electric processing condition applied across an inter-electrode space between the wire electrode and the workpiece is changed from a cutting phase to a welding phase in which the wire electrode is fused partially at some spots along a cutting path of a predetermined contour on the workpiece to weld together the cut-out part and the workpiece at the fused spot on the wire electrode.
