Description

[0001] PORTABLE TYPE FRICTION STIR WELDING APPARATUS [0002]

The present invention relates to a portable friction stir joining device having a simplified overall size.

Lightweight alloys utilizing lightweight materials are widely used in various industrial fields such as transportation equipment such as automobiles, aircrafts and ships, and construction and civil engineering fields. Assembly of various devices and structures using such a lightweight alloy is performed by a bonding process.

Friction Stir Welding (FSW) has been developed and applied as a technique for joining the above-described lightweight alloys.

When the non-consumable rotary tool, which is a hard material, is brought into contact with the abutting surface of the abutting members while rotating at a high speed as compared with the abutting member to be bonded, heat is generated due to mutual friction between the rotating tool and the abutting member, The material of the periphery is softened and the joining members are joined on the principle that the materials on both sides of the joining face are forcibly mixed by the plastic flow of the material by the stirring of the rotary tool. Such friction stir joining does not involve melting of the joining member Therefore, it is possible to prevent welding defects occurring in conventional melting welding, and harmful substances are not discharged during the bonding process, and thus, it is widely used as an environmentally friendly bonding technique.

As an apparatus for performing the above-described friction stir welding, there are known an apparatus for performing the friction stir welding as described in Korean Registered Patent No. 1143941 (Registered Date: 2012. 05. 08, Name: Friction Stir Welding Apparatus for Straight Welding), Korean Registered Patent No. 0500514 (Registered trademark) No. 1067864 (registered on September 20, 2011, entitled "Gantry Type Friction Stir Welding Apparatus"), And "Korean Registered Patent No. 0970518 (registered on June, 2010, titled: Linear Friction Welding Apparatus and Method)".
