1. the electrode position control method in the serial arc welding, be used for before welding beginning control in advance the utmost point and after go the position of extremely relative sealing wire, constitute by following step:

  • The voltage detecting step, it is by the current/voltage detecting unit, detects and voltage as the contacted described utmost point in advance of the welding work pieces of welding object and the described back row utmost point;

    The sensing detection step, it is by the sensing detection processing unit, according to the electric variation by the voltage of the detected described utmost point in advance of described voltage detecting step and the described back row utmost point, detects the positional information of described welding work pieces;

    Revisal amount calculation procedure, it is by revisal amount calculation processing unit, according to positional information, calculate the revisal amount that the position deviation of the described sealing wire of the described in advance utmost point and the extremely relative teaching in advance of described back row is carried out revisal of being used for by the detected described welding work pieces of described sensing detection step;

    WithPosition revisal step, it plans processing unit by the robot trajectory, to add or to deduct the mode of the described revisal amount of being calculated by described revisal amount calculation procedure, comes the position of the described utmost point in advance of revisal and the extremely relative described sealing wire of described back row.
