A system managing a polishing state of tips of a welding gun of each welding robot installed in a production line of a vehicle includes: a robot controller storing tip polishing data including the number of polishing of the tips and a polishing amount of the tips generated after each tip dressing of the welding gun; and a server collecting the tip polishing data from the robot controller to store the collected data according to robot identification information of the robot and learning the store data through artificial neural network to generate reference data determining the polishing state of the tips corresponding to the robot identification information. The robot controller sets artificial neural network of the robot based on the reference data and determines whether a polishing state of the tips according to the number of polishing and the polishing amount of the tips is normal.

A resistance welding machine, particularly suited to carry out repairs on metallic bodies, includes a machine body housing a rechargeable electric battery for supplying the electrical energy that is necessary for the welding cycle, a rod carrying the welding electrode, and a rod carrying the earth electrode. Both of the earth rod and the welding rod are electrically connected to the battery, which is the only source of electrical energy for the resistance welding machine.

A component loading-welding system for welding a component panel to a vehicle body panel includes a rotation portion body having first and second opposing sides. The first opposing side is coupled to a robot arm. A picking device is installed in the rotation portion body and is configured to hold and release the component panel. A vehicle body pressurizing tip is installed in the rotation portion body. A pressurizing portion body is rotatably installed at the second opposing side of the rotation portion body. A pin clamp is installed in the pressurizing portion body and is configured to clamp the component panel. A component pressurizing tip is installed in the pressurizing portion body and is configured to apply pressure to the component panel. A multi point projection welding method is also disclosed.

A weld gun having a weld arm including a 3-dimensional printed structure supporting a welding electrode. The 3-dimensional printed structure can be rapidly produced and provides the structural support for the at least one electrode. The weld arm can be manufactured quickly and are generally lighter than forged/machined arms and can be used with relatively smaller actuators than a comparable forged/machined arm.

Provided is a spatter scattering prevention apparatus that eliminates the necessity to, for example, remove scattered spatters and thus makes it possible to facilitate maintenance work, and also provided is a flash butt welder including the spatter scattering prevention apparatus. The spatter scattering prevention apparatus 1 according to the present invention is characterized by being configured to form a water screen in midair in the vicinity of a welding spot, at which welding is performed, wherein the water screen is for preventing spatters, generated during the welding, from scattering. The spatter scattering prevention apparatus is also characterized by being configured to form the water screen on one side in a lateral direction of the welding spot and form the water screen on the other side, laterally opposite to the one side, of the welding spot.

Device (10) for manufacturing a component compound by resistance welding, comprises a welding electrode (12) for transmitting an electric current to a joining element (17) and for exerting a joining force onto the joining element (17) along a joining direction (22) in order to establish a connection of the joining element (17) with a structural element by resistance welding; as well as a positioning device (20) for positioning at least one joining element (17) on the axis of the joining direction (22) in order to contact and particularly apply a force to the joining element (17) by means of the welding electrode (12). The positioning device (20) comprises a retention device (30) for exerting a retention force onto the joining element (17), wherein the retention device (30) is movably arranged.

A welding apparatus includes a main unit which supports, optionally indirectly, a first electrode and a second electrode which can be crossed by an electric current in order to perform welding treatments; a device for the temporary release of a supporting arm of the first electrode is associated with the unit and is selectively activatable to temporarily allow the movement of the arm. The device further includes a lever for the actuation of the body, which can slide at least between a first configuration, in which it is accommodated in a parallel manner in the body, and a second configuration, in which it protrudes from the body and a terminal portion thereof is retained rotatably by the body.

Systems and methods are provided for exchanging electrode tips, e.g., electrode tips used in resistance spot welding, and disposing of used/unusable electrode tips. Used/unusable electrode tips may be collected, e.g., while within an assembly line. Such used/unusable electrode tips may be routed to a receptacle(s) reside outside the assembly line. Accordingly, disposing or removing of the used/unusable electrode tips can be accomplished without stopping the assembly line, and decreasing any chance for safety events.
