Abstract

The invention relates to a carbon dioxide arc welding wire with the small diameter of 1.6 mm and the high alloy content. The welding wire comprises 1.6-mm welding wire skin and a flux core. The welding wire is characterized in that the flux core is prepared from 1.5%-6% of C, 0.5%-2% of Si, 0.5%-20% of Mn, 10%-25% of Cr, 0%-8% of Ni, 0%-5% of Mo, 0%-7% of Co, 0%-5% of Nb, 0%-10% of V, 0%-2% of W, 0%-10% of Ti and the balance B. According to the carbon dioxide arc welding wire with the small diameter of 1.6 mm and the high alloy content, by means of the formula, multiple alloy elements are contained, the alloy content is high, the welding wire is especially suitable for the occasions needing the high temperature resistance, corrosion resistance, abrasion resistance and impact resistance, and the usage occasion of the flux core welding wire is wider.

Description

technical field [0001] The invention relates to the field of welding wire, in particular to a 1.6mm fine-diameter carbon dioxide gas shielded welding wire with high alloy content. Background technique [0002] Flux-cored welding wire containing alloys can be used in the surface repair of mechanical equipment to enhance the service life of mechanical equipment, and can also be coated on the surface of mechanical equipment to increase the single service life of mechanical equipment and reduce maintenance flat rate. However, the disadvantage of flux-cored wire is that spatter is prone to occur during welding, which reduces the welding repair effect; at the same time, the single formula of traditional flux-cored wire cannot be used in extreme environments and high-strength contact occasions. Contents of the invention [0003] The purpose of the present invention is to provide a weld with high deposition rate, no spatter, good shape and excellent weld seam quality. No preheati...
