Description
Существующие пробы наплавленного металла на склонность его к образованпю трещин в нроцессе сварки не иозвол ют дать количественную оценку этой склонности. Это обсто тельство затрудн ет иропсдение классификации электродов и металлов с точки зрени нрочиостн наплавленного металла в нроцессе сваркп. Предлагаемый способ позвол ет устранить указанный недостаток тем, что оценка склонности наплавленного металла к образованию трепцп в процессе сваркп производпгс по скорости п велнчпне относительной деформации наплавленного металла в процессе сваркп.Existing samples of the deposited metal on its tendency to form cracks in the welding process do not allow a quantitative assessment of this tendency. This circumstance makes it difficult to classify electrodes and metals from the point of view of the weld metal in the welding process. The proposed method makes it possible to eliminate this drawback in that the assessment of the tendency of the deposited metal to form a trepc in the process of welding is made by the speed and value of the relative deformation of the weld metal in the process of welding.
Сущность способа заключаетс в следуюн1;ем. Образец 1 зажимаетс в испытательную машину (см. черте/к) н па пем пропзводнтс нап.лавк валика вдоль образца.

Sample 1 is clamped into a testing machine (see drawing / k) on a piece of rolled wire along the sample. After the stationary temperature zero has been established, during welding, the stresses from external forces are added to the nanofixes by applying an extension of their strength to the ends of the sample. For a given welding mode, the speed is elastic-plastic; deformation in the area of the seam will depend on, from the speed of the roVioiiOK test machine. With an increase in the speed of the machine intersection of the machine heads, the magnitude of the velocity of the deformator and otchippe otosite.1s: o1 1 deformation of the nano-alloyed metal will increase 11 c. For the parameter that determines the strength of the metallope metal, it is proposed to accept the velocity n of the magnitude of the relative metal content in the zope. Irriguey her to the weld.

The cool torque from motor 2 is transmitted to the worm gear 3, then through the interchangeable gears 4, 5, 6, 7, 8 and 9 to the worm gear)) 10. The worm gear of the gearbox 10 is a nut, and the KOTOpoii rotation is carried out The transfer of the screw 11n deformation of the sample 1.
