Embodiment Construction

[0022] The specific implementation manners of the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. The following examples are used to illustrate the present invention, but are not intended to limit the scope of the present invention.

[0023] see figure 1 , and combined with figure 2 As shown, in order to further illustrate the technical effects of the present invention, the following welding methods are used for arc stud welding in flat position, vertical position and supine position for 12mm diameter stainless steel stud 10 and 7mm thick steel plate 30, which specifically include the following step:

[0024] (1) The primer and coating on the surface of the 7mm thick steel plate 30 should be polished before welding, and the steel plate 30 should be dried to remove moisture;

[0025] (2) The end of the stainless steel stud 10 is drilled and filled with aluminum agent, wherein the filling depth of the...

Abstract

The invention discloses a method of welding between a stainless steel stud and a steel plate. A hole is drilled in an end of the steel stud, and is filled with an aluminum agent. Because optimal designing is carried out on the form of the steel stud, and a magnetic ring is adopted for protection on the stainless steel stud, it is effectively avoided that a stainless steel stud is oxidized in the welding process, and the welding quality is guaranteed. Because the stainless steel stud is used instead of a Q235 carbon steel stud, the corrosion resistance of a welding joint of the stainless steelstud is improved, the situation that the stud becomes rusty in the service process of a product is effectively avoided, and service safety of the product is guaranteed; and the welding technology of the stainless steel stud is optimized, the technological parameters such as the welding current, the arc discharge length and the lifting height at the horizontal gesture, the vertical gesture and theposition of facing upward are determined, hot cracks during welding are avoided, the bending performance and the torsion performance of the welding point of the stud are improved, the hardness of thewelding point is reduced, and the comprehensive performance of the welding point is improved.

Description

technical field [0001] The invention relates to the technical field of stainless steel stud welding, and more particularly, relates to a welding method for a stainless steel stud and a steel plate. Background technique [0002] Due to its high strength and corrosion resistance, stainless steel studs are gradually replacing ordinary carbon steel studs in the field of equipment manufacturing. The composition of stainless steel studs is shown in Table 1, and the mechanical properties should comply with Table 2. [0003] Table 1 Chemical composition of stainless steel studs [0004] [0005] Table 2 Mechanical properties of stainless steel studs [0006] [0007] In the actual production process, it is usually necessary to combine stainless steel studs and steel plates to form a bolt-like structure to meet actual needs, which requires welding stainless steel studs and steel plates, while the existing ordinary carbon steel studs The welding method, due to the special prop...
