Acoustic anisotropy as a factor to determine residual stresses in GMAW and CW-GMAW welds
REVISTA DELOSIn the areas of construction and maintenance of welded implements, the acoustic anisotropy of the as received material exerts a great influence on the generated residual stresses levels. In this context, several measurements were taken in order to obtain the acoustic anisotropy, as well as the residual stresses values of welds in simple deposition ...

Droplet transfer in synergic AC GMAW.
DENKI-SEIKO[ELECTRIC FURNACE STEEL], 1990 AC GMA welding was carried out by using an inverter controlled welder which consists of a primary inverter to control the output level and a secondary inverter to control the polarity.The polarity of the base current in conventional synergic DC pulse welding was changed from electrode positive (EP) to electrode negative (EN), and one cycle one droplet ...
