http://www.weldinghelp.org/globular.html WebThe globular transfer mode can theoretically be used to weld Ni-/Co-base alloys, but is seldom used because it creates inconsistent penetration and uneven weld bead contour that promotes the formation of defects. Since the force of gravity is critical for drop detachment and transfer, globular transfer is generally limited to flat position welding.
