Abstract
A welding apparatus (1) for radio-frequency, RF, welding, comprises: a clamp (10) having two electrodes (100, 101; 100′, 101′) being movable with respect to one another for clamping one or more items (2; 2′) therebetween for a welding process; and an RF power supply (11) for providing an RF welding current to the electrodes (100, 101; 100′, 101′) of the clamp (10), the RF power supply being adapted to change the frequency of the RF welding current during the welding process.
Claims15
A portable welding apparatus for radio-frequency, RF, welding, comprising:
- a clamp having two electrodes being movable with respect to one another for clamping one or more items therebetween for a welding process, the clamp comprising a handle operable by a user to displace one of the electrodes relative to the other;
- and
- an RF power supply for providing an RF welding current to the electrodes of the clamp, the RF power supply being adapted to change the frequency of the RF welding current during the welding process, the RF power supply comprising an electrical battery as a power source.
A method for radio-frequency, RF, welding, using a portable welding apparatus comprising a clamp having two electrodes and an RF power supply, the method comprising:
- clamping, with the clamp, one or more items between the two electrodes for a welding process, wherein the clamp comprises a handle configured to be operated by a user, the electrodes being movable with respect to one another by operating the handle;
- providing an RF welding current to the electrodes of the clamp, with the RF power supply, for welding the one or more items;
- changing the frequency of the RF welding current, with the RF power supply, during the welding process;
- and
- releasing the welded one or more items from the clamp by moving the electrodes with respect to one another,
- wherein the RF power supply comprises an electrical battery as a power source.
