Abstract
A first electrode and a second electrode carry out welding in cooperation with each other. A power supply applies a first voltage between the first electrode and the second electrode. A control device controls whether to carry out welding on a first object on the basis of information that varies with a material of the first object and that has been detected in a state where the first object is in contact with the first electrode and the second electrode.
Claims2
A welding method that uses a welding device that has a movable first electrode and a fixed second electrode that are configured to carry out welding in cooperation with each other by applying a welding voltage between the first electrode and the second electrode, the welding method comprising:
- detecting vibration information with a vibration detecting unit installed near the second electrode, the vibration information varying with a material of a object in a state where the object is in contact with the first electrode and the second electrode;
- determining whether the object is a welding target based on the detected vibration information;
- determining whether the object is a hand or finger based on the detected vibration information;
- controlling whether to initiate welding on the object by applying the welding voltage based on the determination that the object is a welding target;
- and controlling whether to not-initiate welding on the object based on the determination that the object is not a welding target.
A welding device comprising:
- a movable first electrode and a fixed second electrode that are configured to carry out welding in, cooperation with each other by applying a welding voltage between the first electrode and the second electrode;
- a vibration detecting unit installed near the second electrode and configured to detect vibration information in a state where the first electrode and the second electrode are in contact with a object, a control device configured to perform the following:
- determine whether the object is a welding target based on the detected vibration information;
- determine whether the object is a hand or finger based on the detected vibration information;
- control whether to initiate welding on the object based on the determination of whether the object is a welding target;
- and control whether to not-initiate welding on the object based on the determination that the object is a hand or finger.
