COMPARATIVE STUDY OF THE TENSILE STRESS OF DIAGONAL SIEVES PRODUCED BY PLASMA WELDING AND HARD SOLDERING PROCESS

Hot Sieves have a rather wide application in different branches of industry. This paper presents studies related to tensile strain of diagonal sieves. The bifilar sieve, type "110", with square opening, wire made of steel X10 CrNi 18-8, (tensile strength R-m = 500-700 N / mm(2), elongation delta = 30-50%), wire diameter 0.50 nun, width 40 mm, length 200 nun was tested. Comparative analysis of sieve joint made by plasma welding and hard soldering was carried out. Experiment was carried out for tensile force of 60 N on bifilar steel sieve with square openings. For tests by straining tearing machine ZWICK ROELL Z010 was used. Obtained results show that hard soldered sieve joint has significantly better mechanical characteristics than plasma welded joint.
