24、lled increase of the beam power at the beginning of welding 3.2 slope down controlled decrease of the beam power at the end of welding. The slope down region is the region on the workpiece in which the effects of slope down occur. It can consist of one or two areas, depending on the selected welding
25、 mode: a) in full penetration welding: a region where beam penetration is still complete; a region where penetration is partial or decreasing. b) in partial penetration welding: a region where penetration decreases continuously.
