Abstract

The invention provides a stainless steel active rosin flux for arc welding and a preparation method thereof. A formula of the stainless steel active rosin flux for arc welding comprises the following components in percentage by weight: 25-35 percent of SiO2, 0.7-1.5 percent of B2O3, 7-10 percent of TiO2, 16-26 percent of Cr2O3 and 38-42 percent of CaF2. The stainless steel active rosin flux for arc welding is used in the arc welding process of a stainless steel material, so that the weld penetration depth is increased, and the problem that the one-time welding depth of the stainless steel material does not surpass 3 millimeter when the conventional arc welding is adopted is solved.

Description

technical field [0001] The invention relates to a stainless steel active flux and a preparation method thereof, in particular to a stainless steel active flux for arc welding and a preparation method thereof. Background technique [0002] Argon arc welding is a kind of arc welding, which uses the arc burned between the continuously fed welding wire and the workpiece as the heat source, and the gas shielded arc ejected from the torch nozzle is used for welding. At present, argon arc welding is a commonly used method, which can be applied to most major metals, including carbon steel and alloy steel. Argon arc welding of stainless steel welded pipes requires deep penetration, no oxide inclusions, and a heat-affected zone as small as possible. Argon arc welding with tungsten inert gas protection has good adaptability, high welding quality, and good penetration performance. Products are widely used in chemical industry, nuclear industry and food industry. At present, when conve...
