- Abstract
The first in the world practice experience of production of the welded-forged structure of the lower frame of70/90 MN forging press with thickness of welded butts in the range of 3000-3800 nun was described. The total weight of the structure amounted to 160-2001. During manufacture the technology of electroslag welding using consumable nozzle was used. The role of the fixture belonged to the closed box-like shape of the welded billets themselves with stiffeners. The welded billet was subjected to normalizing with tempering and ultrasonic testing. The gained experience in producing welds of super-large cross sections can be used in development of methods for calculation of expected deformations and technical procedures of their control. 8 Ref., 4 Figures.
