Ultrasound wave and melt pole electrical arc compound welding method
The invention provides a weld method compounding an ultrasonic and a gas metal arc welding so as to make use of the cavitation effect and the vibration effect of the ultrasonic to lead welding drops generated by the gas metal arc welding to be smoothly transmitted to a welding pool when the drops are still small. And when in welding, an electric arc shrinks under the effect of the ultrasonic and then the stiffness of the electric arc can be enhanced, which has a significant application value for welding of special positions such as a full-position welding, an overhead position welding, a flat position welding and a horizontal position welding, etc.. The invention includes the following steps: an ultrasonic generator is connected with an ultrasonic transducer 2 to convert ultrasonic energy into mechanical vibration; an ultrasonic transformer 3 enlarges amplitude; a conductive tip 5 is combined with the ultrasonic transformer; a protective gas nozzle 4 is fixed on the vibration node of the transformer; a welding wire 1 is connected with the conductive tip 5 to start a welding power supply 9 and then start an ultrasonic power supply after the electric arc becomes stable, then the transducer converts electrical energy into vibration and the ultrasonic transformer enlarges the ultrasonic amplitude which is transmitted to a melting electrode.

Composite welding method of ultrasound wave and non-melt pole electrical arc
InactiveCN101219499AImprove straightnessImproved arc stabilityElectrode vibration holdersTransformerEngineering
The invention discloses a welding method of compounding ultrasonic and nonconsumable electrode voltaic arc. Under the welding condition of protection of nonconsumable electrode gas, the ultrasonic is conducted into welding arc through the conductive electrode and the voltaic arc obviously contracts after ultrasound is carried on. The invention not only has the advantages of stable welding process and high welding and forming quality which normal TIG welding has, but also can improve weld penetration of single-pass welding and therefore the method can realize high quality welding under normal welding condition. The invention converts the high frequency electrical signals of ultrasound supply into mechanical vibration through an energy conversion device and the mechanical vibration is amplified by an amplitude transformer, and then is transmitted to an electrode studded in the amplitude transformer so as to generate supersonic vibration of corresponding frequency on the electrode. The input power of the ultrasound can be adjusted at will between 1W to 1000W and then welding is carried out by the method of normal gas metal arc welding. When voltaic arc is applied to processing pieces, the energy is concentrated, thereby effectively improving utilization ratio of voltaic arc during welding.
