摘要： A system and method of electric arc welding that includes a welding apparatus having an electric arc welder torch with sensors to determine the absolute position of the torch tip and the relative position of the torch tip to the weld joint during automatic welding. Combining absolute and relative positional data can be used to adjust the path of the robot during automated or robotic welding in response to variations in the weld joint.

摘要： A method and a system for controlling a welding operation is provided by a welding machine controlled by an automatic motion generating mechanism. The method includes the steps of acquiring a set of welding data during the welding operation; computing at least a first part of the set of welding data and at least a second part of the set of welding data providing computed data, wherein the computed data indicate an abnormality; and transferring an abnormality output to a robot controller, which is controlling the welding machine and the automatic motion generating mechanism.

摘要： This method for acquiring weld pass information pertaining to execution conditions for a weld pass for welding two workpieces, which are to be welded by the welding robot, includes: a step in which a weld pass for welding the two workpieces is extracted from 3D CAD data; a step in which a wall determination model having a predetermined 3D shape is prepared; a step in which the wall determination model is positioned in the direction extending towards the outside of the weld pass, the end of welding which is the starting point or ending point of the weld pass serving as a reference; and a step in which, for the positioned wall determination model, a determination is made as to whether there is interference from a wall surface demarcated by another member different from the two workpieces.

摘要： A welding position is provided which can prevent surface pressure drop in a seal bead in a pair of metal gaskets is determined. Joint surfaces of a pair of metal gaskets are joined to each other by welding. The pair of metal gaskets include a seal bead that encloses opening and a plurality of structures that bulge from the joint surfaces. A pressure-sensitive medium is sandwiched between the seal bead and a member to be engaged so that the pair of joined metal gaskets and the member to be engaged are stacked on one another, and the pair of joined metal gaskets are tightly engaged with the member to be engaged. The tight engagement is released, and a surface-pressure-drop location in the seal bead is detected based on a mark which remains on the pressure-sensitive medium after the release of the tight engagement. An additional welding position is determined in a rectangular area which is defined by four sides contacting a first structure closest to the surface-pressure-drop location and a second structure closest to the first structure to surround the first structure and the second structure.

摘要： A non-consumable electrode arc-welding method is provided for causing a welding machine to output or stop a welding current in accordance with at least an ON state and an OFF state of a start signal. In the method, a start signal is switched between an ON state and an OFF state, thereby controlling the on/off operation of the welding machine. Further, an operation mode instruction signal is switched between a normal mode and an interval mode, thereby controlling the operation mode of the welding machine. When the operation mode instruction signal indicates the interval mode and also the start signal is in the ON state, the welding current is outputted in a welding current output period. Then, the output of the welding current is suspended in a welding current interval period successively following the welding current output period.
