Abstract
Method for monitoring the behaviour of a welding gun and handheld welding gun for welding an element to a component comprising a sensor unit adapted to measure different parameters during the welding process, a processing system with a control card adapted to control one or more parameters of the welding process, wherein the sensor unit comprises a gyroscope sensor mounted within the housing, wherein the gyroscope sensor is arranged on the control card.
Claims14
A handheld welding gun for welding a fastener to a component according to a welding process, the handheld welding gun comprising:
- a housing with a main portion and a grip with a trigger, the grip extending from the main portion;
- a holding unit mounted on the main portion and adapted to hold the fastener;
- a linear actuator adapted to actuate the holding unit in order to move the fastener between a lift position and a plunge position;
- a nozzle surrounding the holding unit and adapted to contact the component;
- a welding current contact element arranged in the housing and adapted to direct a welding current to the fastener;
- a processing system with a control card, wherein the control card is adapted to control the welding process;
- and
- a sensor unit adapted to measure different parameters during the welding process, the sensor unit including a gyroscope sensor mounted within the housing and arranged on the control card.
A method for monitoring the behaviour of a handheld welding gun during welding of a fastener to a component according to a welding process, the method comprising:
- providing a handheld welding gun including:
- a housing with a main portion and a grip with a trigger, the grip extending from the main portion;
- a holding unit mounted on the main portion and adapted to hold the fastener;
- a linear actuator adapted to actuate the holding unit in order to move the fastener between a lift position and a plunge position;
- a nozzle surrounding the holding unit and adapted to contact the component;
- a welding current contact element arranged in the housing and adapted to direct a welding current to the fastener;
- a processing system with a control card adapted to control the welding process;
- and
- a sensor unit adapted to measure different parameters during the welding process, the sensor unit including a gyroscope sensor mounted within the housing;
- determining an orientation of the handheld welding gun using the gyroscope sensor;
- and
- adapting a parameter of the welding process associated with a period after its initiation based on the orientation of the handheld welding gun.
