METHOD FOR WIDE-LAYER WELDING ON Russian patent published in 2002 - IPC

FIELD: welding processes and equipment, namely hardening surfaces of machine parts. SUBSTANCE: method comprises steps of uniformly arranging thermocompensation consumable layer of silicates over horizontal plate-type electrode along its length and width; realizing arrangement of said layer through flux sublayer spaced from article by distance exceeding length of arc gap by 3-5 times; using as thermocompensation layer monolythic silicate glass whose thickness is equal to 0.5-1.5 of thickness value of plate type electrode. EFFECT: lowered mass of slag scum, uniform alloying degree and physico-mechanical properties of welded-on metal. 2 cl, 1 dwg, 1 tbl
