Abstract

The invention provides a friction stir welding device with the adjustable stirring pin length and a two-sided welding method. The friction stir welding device with the adjustable stirring pin length comprises a friction stir welding device main body, a clamping part, a micro hydraulic oil cylinder, a driving motor, a temperature sensor, an ultrasonic probe, an ultrasonic detector, a temperature display, a hydraulic controller, a hydraulic pump and an operation controller. The friction stir welding device main body is mounted below the clamping part and is hollow. A stirring pin is arranged in the friction stir welding device main body. A stirring head is arranged on the lower portion of the stirring pin. A rotary joint is connected with the upper portion of the stirring pin. The micro hydraulic oil cylinder is mounted between the stirring pin and the rotary joint. The friction stir welding device can automatically adapt to various welding depths and welding demands of variable cross-section components, welded surfaces are smoother and more attractive, the welding strength is higher, the welding effect is better, and the friction stir welding device is high in automation degree and easy and convenient to operate and control.

Description

technical field [0001] The invention relates to the field of welding technology, in particular to a friction stir welding device and a welding method with an adjustable stirring pin length. Background technique [0002] Welded joints, such as butt welds, are used to join metal parts. Butt seams use one or more welds at overlapping portions of material to join overlapping surfaces. Welding techniques typically use elevated temperatures to bond metals and metal alloys. Friction stir welding is a relatively new method that uses a rotating tool to join two workpieces that are solid, or to repair cracks in a single workpiece. The material to be welded is heated and softened by rubbing the shoulders of the rotating tool into contact with the material. The tool goes through the seam and stirs the material together. Thus achieving a solid state connection without the need for fillers or the use of shielding gases, friction stir welding will be very advantageous when used in airc...
