PRODUCTION OF STEEL SHEET AND STEEL SHEET THUS MADE

摘要

FIELD: process engineering.SUBSTANCE: invention relates to production of steel sheet articles from different-depth steel sheet or strips. Billets are welded together along the butt to get the weld (7) composed by edges of steel sheet or strip workpiece. To rule out loss of quenched structure produced by heating to austenitising temperature, at least one edge of sheet or strip (8, 9) is coated before welding with thick fluid or solid powder or aerosol-like matter including at least one component increasing the strength of the weld (10).EFFECT: higher weld strength.28 cl, 2 dwg
