specific Embodiment approach 1

[0008] Specific implementation mode one: combine figure 1 Illustrate this embodiment, the method of this embodiment is completed by the following steps: Step 1: put corrosion-resistant metal group 4 into corrosion-resistant container 2; Step 2: inject cleaning solution 3 in the corrosion-resistant container 2; Step 3: Let stirring The head 1 is rotated and inserted into the corrosion-resistant container 2, so that it is fully immersed in the cleaning solution and fully in contact with the corrosion-resistant metal cluster 4 (that is, the stirring head 1 is inserted into the corrosion-resistant metal cluster 4), and the corrosion-resistant metal cluster 4 is fixed in the corrosion-resistant container 2; Step 4: After the adhesive material 5 on the surface of the stirring head 1 is fully dissolved, pull out the stirring head 1; Step 5: Rinse the stirring head 1 with water to remove the residual cleaning solution on its surface, and then use a hair dryer to remove It is blown dry...

specific Embodiment approach 2

[0009] Specific embodiment 2: In step 1 of this embodiment, the corrosion-resistant metal cluster 4 is made of stainless steel. Metal cluster 4 has better corrosion resistance. Others are the same as in the first embodiment.

specific Embodiment approach 3

[0010] Embodiment 3: The corrosion-resistant container 2 in step 1 of this embodiment is made of stainless steel, glass, ceramics or polymer materials. Container 2 is more resistant to corrosion. Others are the same as in the first embodiment.

Abstract

The invention discloses a method for cleaning a stirring head used for friction stir welding, and relates to a method for cleaning a stirring head. Aiming at the problems of scratching the surface of the stirring head and low cleaning speed when the conventional stirring head used for the friction stir welding is cleaned, the method comprises the following steps of: 1, placing a corrosion resisting metal cluster in a corrosion resisting container; 2, injecting cleaning solution into the corrosion resisting container; 3, rotatably inserting the stirring head into the corrosion resisting container to ensure that the stirring head is fully immersed into the cleaning solution and fully contacts with the corrosion resisting metal cluster, wherein the corrosion resisting metal cluster is fixed on an inner wall of the corrosion resisting container; 4, after adhesive materials on the surface of the stirring head are fully dissolved, pulling the stirring head out; 5, washing the stirring head with water to remove the cleaning solution from the surface of the stirring head and then drying the stirring head with a fan to obtain a clean stirring head and complete the whole cleaning process. The method of the invention is used for cleaning the stirring head used for the friction stir welding.

Description

technical field [0001] The invention relates to a cleaning method for a stirring head. Background technique [0002] Friction stir welding is a new type of solid-phase joining technology, which overcomes the problems of welding defects such as cracks and pores in the fusion welding method, and can realize efficient and high-quality joining of aluminum, magnesium and their alloys. However, when the friction stir welding method is used to weld each weld seam, after the stirring head is pulled out, a layer of material to be welded will adhere to the stirring pin. This layer of adhering material changes the geometry of the stirring head, and if the next weld is continued without cleaning, it will affect the consistency and stability of the welding process. Especially for welding materials that are easy to adhere (such as copper and its alloys), the impact is more serious, and the adhesion layer will accumulate and thicken, seriously affecting the normal welding process.
