Abstract
Welding is carried out using a consumable electrode while applying to a welding wire a vibration at a frequency of 500 Hz or more and an amplitude of 0.01 to 0.5 mm. The vibration is preferably applied in a direction crossing the feeding direction of the welding wire. A vibration under these conditions is preferably applied to a tip of the welding wire by using the forced vibration or resonance of the welding torch or the resonance of the welding wire itself.
Claims9
A method of welding using a consumable electrode, the method comprising the step of:
- carrying out welding while applying to a welding wire a vibration at a frequency of 500 Hz or more and an amplitude of 0.01 to 0.5 mm.
An apparatus for welding using a consumable electrode, comprising:
- a handle;
- a torch, the torch configured to feed a welding wire therethrough;
- and
- a vibration exciter arranged between the handle and the torch, the vibration exciter configured to apply to the torch a vibration in a direction crossing the feeding direction of the welding wire to thereby apply a vibration to the welding wire fed through the torch,
- wherein the vibration to be applied to the welding wire fed through the torch has a frequency of 500 Hz or more and an amplitude of 0.01 to 0.5 mm.
An apparatus for welding using a consumable electrode, comprising:
- a torch, the torch configured to feed a welding wire therethrough;
- and
- a vibrator having a vibration connector and being connected to the torch via the vibration connector, the vibrator configured to apply to the torch a vibration in a direction crossing the feeding direction of the welding wire to thereby apply a vibration to the welding wire fed through the torch,
- wherein the vibration to be applied to the welding wire fed through the torch has a frequency of 500 Hz or more and an amplitude of 0.01 to 0.5 mm.
