TH49270B - Solid wire without quenching for alloy welding - Google Patents

Abstract

DC60 (17/10/45), a quenched solid wire for arc welding, has a hole opening on its circumference and has a wider inner profile than at Each opening and / or hole whose part is not illuminated by incoming light from the outside. Sulfides and oils, which contain poly Isobutene appears in the pit. And / or on the surface of the wire, the latter appear in an amount of 0.1 - 2g / 10kg wire. Twenty or more holes appear in total per circumference and along the circumference. Effective wells were 0.5%, all - 50% alone, 0.01 - 2g of oil appeared per wire, 10 Kg 0.1 - 0.5 g / 10g of 0.1 - 10- (mu) m - particles - MoS2 diameter appeared. Is in a "bottleneck and / or hollow" hole on the surface of the wire, or Under the surface The instantaneous mass of wire 2-10 ppm, with the total mass / mass of the wire of K's compound K appear in the hole and / or on the surface of the wire. This ensures good feeding ability and lubrication properties and little metal splash. A solid, non-plating wire for arc welding has a hole opening on its circumference and is wider on the inside than at Each opening and / or hole whose part is not illuminated by external light. Sulfides and oils, which contain poly Isobutene appears in the hole. And / or on the surface of the wire, the latter appears in an amount of 0.1 - 2g / 10kg wire. Twenty or more holes appear in total per circumference and along the circumference. The effective wells were 0.5% all - 50% alone. 0.01 - 2g of oil was present per wire 10Kg. 0.1-0.5 g / 10g of 0.1-10-um - particle - MoS2 diameter was present in " Bottle-like and / or hollow-like holes "on the surface of the wire or Under the surface The instantaneous mass of wire 2-10 ppm with the total mass / mass of the wire of the compound K in the manner K is present in the hole and / or on the surface of the wire. This ensures good feeding ability and lubrication properties and little metal splash.
