preparation example Construction

[0025] See figure 1 The present invention also proposes a preparation method of active flux for tungsten inert gas argon arc welding, comprising the following steps:

[0026] S10: Grinding and pulverizing dichromium oxide, manganese oxide, aluminum oxide, and calcium oxide, and then sieving to obtain a solid phase oxidation mixture.

[0027] S11: In this step, manual grinding or mechanical grinding can be used, for example: Weigh chromium oxide, manganese oxide, aluminum oxide, and calcium oxide according to each mass fraction of raw materials and put them into a mortar and grind them together into powder, and then use a sieve with a pore size of less than 74 microns to screen the ground powder, so that the particle size of the ground solid phase oxide is all less than 74 microns.

[0028] S12: Put the solid-phase oxidation mixture in a drying room with a relative humidity of 40% for 2h-3h.

[0029] S20: After drying the solid phase oxidation mixture, add absolute ethanol an...

Embodiment 1

[0033] Put 40% chromium oxide, 15% manganese oxide, 20% aluminum oxide, and 15% calcium oxide into a grinding vessel and grind them into powder, and then use a sieve with a pore size of less than 74 microns to screen the ground powder , so that the particle size of the solid phase oxide after grinding is less than 74 microns; put the solid phase oxidation mixture into a drying room with a relative humidity of 40% for 2 hours; put the dried solid phase oxidation mixture into a container, and evenly add 10% absolute ethanol, in the process of adding absolute ethanol, constantly stir the solid-phase oxidation mixture and absolute ethanol, so that the mixture of the two is adjusted to a paste, and the activity of the tungsten inert gas argon arc welding of the present invention is obtained. flux.

Embodiment 2

[0035] Put 30% chromium oxide, 18% manganese oxide, 25% aluminum oxide, and 22% calcium oxide into a grinding vessel and grind them into powder, and then use a sieve with a pore size of less than 74 microns to screen the ground powder , so that the particle size of the solid phase oxide after grinding is less than 74 microns; the solid phase oxidation mixture is put into a drying room with a relative humidity of 40% for 2.5 hours; the dried solid phase oxidation mixture is put into a container, uniformly Add 5% absolute ethanol, and in the process of adding absolute ethanol, constantly stir the solid-phase oxidation mixture and absolute ethanol, so that the mixture of the two is adjusted to a paste, and the tungsten inert gas argon arc welding of the present invention is obtained. active flux.

Abstract

The invention discloses an active flux for tungsten inert gas argon arc welding, a preparation method and a use method thereof. Among them, the active flux of tungsten inert gas argon arc welding includes: including 30%-40% chromium oxide, 15%-25% manganese oxide, 20%-30% aluminum oxide, 15%-25% calcium oxide and 5%-10% absolute ethanol, the active flux of the tungsten inert gas argon arc welding of the present invention can greatly improve the weld penetration and depth-to-width ratio of the target workpiece in use, and the efficiency of welding is improved. improve. Secondly, after welding with the active flux of tungsten inert gas argon arc welding, the welding surface of the target work has a good shape, no slag inclusion, no porosity, reasonable reinforcement and fusion width, and the adverse effects are greatly reduced. At the same time, the invention can increase the hardness of the weld seam, the heat-affected zone, and the base material near the weld seam to a certain extent. The tensile test proves that the tensile strength of the welding seam using the present invention is higher than that of the parent material.

Description

technical field [0001] The invention relates to the technical field of dock welding, in particular to an active flux for tungsten inert gas argon arc welding and its preparation method and use method. Background technique [0002] Non-melting extremely inert gas shielded arc welding (TIGTungstenInertGasWelding) welding technology was first proposed by the Ukrainian Barton Research in the 1960s, and it has been extensively studied in China since the 1990s. At present, although corresponding active fluxes have been successfully developed for low-carbon steel, stainless steel, aluminum alloy, titanium alloy and other metals at home and abroad, they have not been widely promoted in industry. Especially the active flux formula applied to the 320 marine pipeline steel in the field of ship welding is almost blank at present. Contents of the invention [0003] The main purpose of the present invention is to provide an active flux for tungsten inert gas argon arc welding, aiming a...
