Information × Registration Number 0205U007283, 0105U001426 , R & D reports Title Development of the technology of multipass laser and hybrid laser-arc welding of steels with thickness to 50mm. popup.stage_title Head Shelyagin Vladimir Dmitrievich, Кандидат технічних наук Registration Date 24-01-2006 Organization E.O.Paton Electric Welding Institute of the National of Sciences of Ukraine popup.description2 Base technological techniques of of multipass laser and hybrid laser-arc welding of steels 20, Ст.3пс, 09Г2С и Х70 with thickness 10..46mm with filling wire Св-08Г2С (1,2... 2,0mm) was developed. Hybrid fourpass welding allowed to obtain the junctions ferrite-pearlite structure with hardness up to HV0,05-260…280 and impact elasticity closed to junctions produced by arc welding. But for all that specific to junctions produced by arc welding. But for all that specific energy was reduced in 6-8 times, that greatly decrease the residual thermal deformations.
