Abstract

The invention relates to a one-face welding and two-face forming welding wire with back face argon-filling-free protection. The welding wire is formed by mixing and evenly stirring powder raw materials and sodium water glass with the weight accounting for 20% to 30% of the total weight of the powder raw materials, coating a welding core with the mixture in a pressed mode, and then drying the welding core coated with the mixture. The powder raw materials comprise, by weight, 20 parts to 40 parts of marble, 5 parts to 19 parts of fluorite, 1 part to 5 parts of titanium dioxide, 1 part to 5 parts of quartz, 2 parts to 6 parts of silicon iron, 1 part to 6 parts of ferrotitanium, 1 part to 4 parts of electrolytic manganese, 2 parts to 30 parts of rutile and 3 parts to 10 parts of chromium metal. When the welding wire carries out one-face welding and two-face forming, the coating on the surface of the welding wire will be molten to form a thin slag layer to permeate to the back face of a workpiece to carry out slag protection on welding seams, the welding technology is good in performance, whole-position welding technology performance is provided, the appearance of the welding seams is attractive, the deslagging performance is excellent, and the welding cost and difficulty can be reduced.

Description

technical field [0001] The invention belongs to the field of welding materials, and relates to a welding wire, in particular to a welding wire, and more particularly to a welding wire with a single-sided welding and double-sided forming and the back side free of argon gas protection. Background technique [0002] TIG welding (also commonly referred to as TIG welding) TIG welding, often referred to as TIG welding, is an arc welding method that generates heat between a non-consumable electrode and a workpiece; electrode rods, molten pools , The arc and the heating area near the work are protected by a gaseous state to isolate the atmosphere from mixing. This protection is supplied by a gas or mixed gas flow, usually an inert gas, which must be able to provide full protection, because even a very small amount of air is mixed. Will contaminate the weld bead. [0003] Tungsten argon arc welding is a welding method that uses a tungsten rod as an electrode and argon gas for protec...
