| Abstract: | In order to enhance the mechanical properties of weld by using ultrasonic vibration,a new method of twin-arc tungsten inert-gas(TIG) welding was developed.The welding will be completed by jointly using combined ultrasonic arc and ordinary DC arc technology.The ultrasonic arc was used for injecting(ultrasound) excitation into the molten pool to improve weld quality,and the DC arc was used as main heat source to increase deposition efficiency.The feasibility experiment of the welding system was done by(using)... |
