The weld penetration and weld width of the PU-GMAW increased by 86 and 38.2%, respectively.Ībdullah A, Sichani EF (2009) Experimental study of attenuation coefficient of ultrasonic waves in concrete and plaster. Compared with the GMAW, the weld penetration and weld width of the CU-GMAW increased by 100 and 23.6%, respectively. The peak current of GMAW, PU-GMAW, and CU-GMAW were 300A, 350A, and 330A, respectively. The weld pool front angle of GMAW, PU-GMAW, and CU-GMAW are 17.75°, 12.3°, and 10°, respectively. The droplet transfer cycles of the GMAW, the PU-GMAW, and the CU-GMAW were 199.5, 210, and 222 ms, respectively. The PU-GMAW and the CU-GMAW both have their own advantages under different evaluation criterions. The results showed that the pulsed ultrasonic could assist GMAW. Compared with the continuous ultrasonic-assisted GMAW (CU-GMAW), the influence of PU-GMAW on droplet transfer behavior and weld appearance is discussed. The main purpose of this paper is to study the feasibility of pulsed ultrasonic-assisted GMAW. The new method named as the pulsed ultrasonic-assisted GMAW (PU-GMAW) is studied in this paper, which was enforced by utilizing the pulsed ultrasonic to control the gas metal arc welding (GMAW) process.
