    摘要: A method of starting arc sensing applicable to automatic welding apparatuses carrying out an arc sensing operation, which is a control operation comprising: detecting deviations of a welding electrode from a predetermined path in an up or down direction and right or left direction, by variations of a welding current while welding with a weaving operation; and correcting the deviation.In this method of starting arc sensing, the welding electrode is held in the dwell state while the arc is extremely unstable just after the arc is first generated, a weaving is carried out from a first predetermined time (T.sub.1) after the extreme instability of the arc has been eliminated, a detection and correction by an arc sensing of a deviation in the right and left direction only are carried out from a second predetermined time (T.sub.2) after the arc has become stable in the weaving state; anda detection and a correction by an arc sensing of a deviation in an up and down direction are carried out in addition to the arc sensing in the right and left direction, from a third predetermined time (T.sub.3) after the correction by the arc sensing of the deivation in the right and left direction only has been carried out (FIG. 7).

    摘要: A process in which a base metal film is formed on the surface of a plastic film using a dry plating process, and a liquid containing an organic monomer is then brought in contact with the base metal film, thereby selectively forming a conductive organic polymer coating within any pinhole defects, and effectively filling the defects. A metal film is then formed on top of the base metal film using an electroplating process, thus forming a metal wet plating layer.

    摘要: According to a path correction method in an automatic welding machine in accordance with the invention, the torch TC of a welding machine is grasped by a robot and welding is performed while the welding torch is weaved to the left and right of a welding line. At such time, an integrated value of welding current of the torch weaved with respect to a given welding line is computed every half cycle, the correction direction is decided, the amount of correction is decided by performing a computation, which is based on the integrated value, in dependence upon the correction direction decided, and the weaving path of the torch is corrected by multiplying the decided amount of correction by a predetermined coefficient.
