Technical Field
The utility model relates to the technical field of friction stir welding, in particular to a profiling scraper with a double-ring structure stirring head.
Background
Friction stir welding is a non-fusion welding method. According to the method, a special tool, namely a stirring head, is utilized, the stirring head rotates at a high speed and is inserted into a piece to be welded, a large amount of friction heat is generated between the stirring head and the piece to be welded, the metal starts to advance when in a plastic state, the stirring head guides the plastic metal to the rear of the plastic metal in the welding process, and then the plastic metal is fused through a stirring probe at the end part of the stirring head, so that a compact welding seam is formed by forging under the pressure of the top end. The core of the friction stir welding technology is a stirring head, and the friction stir welding can realize the welding of materials such as aluminum alloy, copper alloy, magnesium alloy, titanium alloy and the like.
In the prior art, when welding harder or softer aluminum alloy, the materials are sticky and are not easy to form, so that the stirring head is sticky; when copper-aluminum dissimilar materials are welded, the hardness and the flow property of the aluminum alloy and the copper alloy are greatly different, and the phenomenon of stirring head sizing also exists. The stirring head adhesive can cover the structural characteristics of the shaft shoulder, so that the friction force and heat generation amount of the welding material are reduced, the surface of the welding line is not formed, tunnel defects are generated, and a high-quality welding joint cannot be obtained.
Therefore, a double-ring structure stirring head profiling scraper is needed to be designed to solve the problems.
