Embodiment 1

[0038] The activator of the present invention is used to perform A-TIG welding on a 321 stainless steel plate with a thickness of 6 mm. Among them, the active agent powder is composed of SiO with a mass percentage of 30% 2 Powder, 8% Cr 2 o 3 Powder, 15% Al 2 o 3 Powder, 13% TiO 2 Powder, 7% MnO 2 Powder, 7% Fe 2 o 3 Powder, 15% B 2 o 3 powder and 5% La 2 o 3Powder composition. WSM-315D full-digital DC pulse argon arc welding machine is used for welding operation. The main welding parameters are: welding current value is 110A~130A, welding voltage value is 10V~14V, welding speed is 2~5m / h, welding torch inclination angle is 70°~80°, the protective gas is argon, and the gas flow rate is 10~20L / min.

[0039] eventually get as figure 1 Frontal photographs of welds shown and as figure 2 The photo of the back of the weld is shown, and the weld tension test is carried out on the welded stainless steel plate, and the test results shown in Table 1 are obtained.

Abstract

The invention belongs to the technical field of stainless steel welding, and particularly relates to a stainless steel A-TIG welding active agent and a welding method. To solve the problem that an existing stainless steel A-TIG welding active agent contains halide, influences are caused to the human body health, the stainless steel A-TIG welding active agent is disclosed. The stainless steel A-TIGwelding active agent comprises active agent powder. The active agent powder comprises, by mass percent, 10%-30% of SiO2 powder, 5%-20% of Cr2O3 powder, 15%-50% of Al2O3 powder, 10%-20% of TiO2 powder, 5%-20% of MnO2 powder, 5%-20% of Fe2O3 powder, 5%-30% of B2O3 powder and 3%-8% of La2O3 powder. The active agent is adopted for conducting stainless steel A-TIG welding, influences of the halide onthe operator health can be avoided, and the welding efficiency can be improved.

Description

technical field [0001] The invention belongs to the technical field of stainless steel welding, and in particular relates to a stainless steel A-TIG welding activator and a welding method. Background technique [0002] Because the traditional TIG welding, that is, non-melting inert gas tungsten shielded welding, has the advantages of high welding quality, stable welding process, many materials suitable for welding, strong reliability, and the weld metal is not easy to deteriorate, so it is widely used. However, with the continuous improvement of welding requirements, this welding method also has certain limitations. For example, due to the limited current bearing capacity of the tungsten electrode, the arc energy density is reduced and its power density is limited, resulting in low deposition efficiency, shallow welding penetration and low production efficiency. [0003] In recent years, under the same welding process, A-TIG welding can effectively increase the welding pene...
