Our university, between 27-29 September carried out experimental work to determine the mechanical properties of the armature A-500S. Experimental work based upon your recommendation was used in the machine ADFS-2001. When the welded joints «back-to-back angles» of a viscous type were broken, the ultimate strength was 620-650 N/mm2. The test results are considered satisfactory.
