Embodiment 1

[0027] A flux-cored welding material, including a steel sheath and flux. The steel sheath is made of 304 stainless steel. The 304 stainless steel strip is placed on the unwinding machine of the flux-cored welding wire forming machine, and the steel strip is rolled into a U shape by the forming machine. Then add the drug core powder obtained in step 2 to the U-shaped groove, control the filling rate of the drug core powder to 25%, and then use the forming machine to roll and close the U-shaped groove, and draw it to a diameter of 1.6mm. Get flux cored wire. The process of making flux is as follows:

[0028] S1. Weigh each component material, and measure a suitable weight of the raw material with an accuracy of 0.01 grams.

[0029] S2. Put each component material into a blender and mix. The stirring rate of the blender is 60-120 rpm, and the stirring time is 3-5 minutes.

[0030] S3. Mix the raw materials and put them into a drying oven for drying. The drying temperature is se...

Abstract

The invention discloses a flux core welding material, and relates to the field of welding materials. The flux core welding material comprises steel skin and soldering flux. The soldering flux comprises an alloy component and a slag system component. The alloy component comprises following components including, by weight, 0.01-0.04 part of C, 21-26 parts of Cr, 11-15 parts of Ni, 0.4-2.6 parts of Mn and 0-1 part of Si. The slag system component comprises following components including, by weight, 20-25 parts of rutile, 21-22 parts of metal chromium, 7.5-8 parts of metal nickel, 5-8 parts of electrolytic manganese metal, 1-5 parts of an aluminum magnesium alloy, 1.5-1.8 parts of quartz, 1-1.8 parts of zirconium quartz, 9-14 parts of albite, 10-15 parts of potassium feldspar, 0.9-3 parts of sodium potassium titanate, 1-4 parts of potassium fluosilicate, 0.2-1 part of bismuth oxide and the balance iron and inevitable impurity materials. The flux core welding material has good welding technology properties that arcs are soft and stable, splashing is little, and deslagging is likely to happen, the appearance of welding lines after welding is free of oxidation tint, the stainless steel natural color is retained, smoothness and attractiveness are achieved, and the problem that the welding lines need to be cleaned after conventional stainless steel welding material welding is reduced.

Description

technical field [0001] The invention relates to the technical field of welding materials, in particular to a flux-cored welding material. Background technique [0002] Flux-cored welding wire is also called tubular welding wire. By adjusting the type and proportion of flux-cored additives, it is very convenient to design various welding materials for different purposes. Because its alloy composition can be adjusted flexibly and conveniently, so many flux-cored welding wires The variety is solid welding wire that cannot be smelted and rolled. [0003] The welding materials currently on the market generally leave the oxidized color of the material at the weld after welding, so the material needs to be pickled after welding, which not only reduces the work efficiency, but also greatly increases the cost. Contents of the invention [0004] (1) Solved technical problems [0005] Aiming at the deficiencies of the prior art, the invention provides a flux-cored welding material,...
