Impoving the quality of products created by additive technologies on the basisi of tig welding

The paper deals with the issues of obtaining minimum waviness surfaces formed by additive processes TIG welding. It is known that geometric parameters melt bead, which form a reproducible workpiece layer layer, are determined both energy and kinematic characteristics process. In this case, laying rollers occurs optimal overlap, as result it possible to achieve maximum density model, however, simultaneous appearance certain due thermodynamic phenomena in bath. proposed model formation bead melt, use made establish rational conditions for out layers. Experimental studies process argon-arc surfacing models given, regression equations determining controlled parameter obtained.
 shown influenced dynamic wave develop under action system forces during bead. An improvement quality products seen optimization methods forming rollers, ensuring stability movement working head, appropriate overlap trajectories along layers layout an amount 0.5e, establishing arc length, maintaining burning.
 response objective functions planes constructed, provide clear illustration dependence on welding modes.
