Description

VIBRATED COMPRESS MEMBER USED IN WELDING PROCESS
Technical Field
The invention relates to a compress member comprising welding assembly vibration member having compress member developed for use in FSW (Friction stir welding) operation.
The invention particularly relates to a compress member containing a vibration member eliminating inner structure failures and stress of extrusion welding plane differences, also conducting fixturing, and extending terminal set life and not requiring additional transducer investment.
Prior Art
Solid form combining and processing technologies are commonly used in the industry to join soft metal alloys difficult to be joined by use of conventional welding techniques. According to the applications, friction stir based operations can be classified in two main categories, namely, welding and processing. Friction stir welding method is convenient particularly for metals other than iron having low melting point and mixed compounds mixing. By use of Friction stir welding (FSW) raw materials too difficult to be welded or different types of raw materials, for instance, aluminium, magnesium, copper, titanium or steel can be joined. Parts to be welded in other friction welding are moved on one another and in this method parts fixed from head to head do not have friction. Friction stir welding (FSW) is an ideal method for connections requiring low cost and high performance indication. Operating principle of friction stir welding is the use of set on the part by help of not melting mixer comprising two parts including shoulder and tip. Such operation is achieved by immersing set having rotating shoulder and stirring tip of different speeds between two plates and moving them along joining line. Parts to be welded in other friction welding are moved on one another and in this method parts fixed from head to head in the table do not have friction. The highest temperature reached in this method is 0.8 times of melting temperature.
It is discovered that ultrasonic help in friction stir welding considerably improved mechanic work in addition to material flow in the welded/processed area, that it broadened process window, that it reduced or eliminated various welding failures and that it developed welding mechanic and micro structural features too. It is known that in present applications roller is used instead of fixture. Fixturing and alignment is made by the press force applied by the rollers. Planarity tolerances from production (extrusion process and similar ones) may be different. Surfaces of two parts welded head to head can not be sensitively aligned due to plane differences, height differences between the parts causes welding failures. Fixturing two parts to be welded by one or several rollers simultaneously moving with tool eliminates such failure. Rollers applies pressure force onto an area close to welding area, onto part instantly and thus provides alignment of parts to one another. In current applications it is seen that ultrasonic vibrations are transmitted via friction stir welding (FSW) instruments or from front of vehicle or back of the vehicle during welding. However, rollers are not used as vibration transmission means minimizing fixturing as well as alignment and welding failures and hitting.
Several studies were conducted to improve friction stir welding performance and new embodiments have been developed. One of them is an invention disclosed under patent application numbered KR2011073974A. The invention relates to friction stir welding device. The friction stir welding device disclosed thereunder comprises a welding tool structured in rotatable form to apply pressure onto a welding made from a preset combining material and to apply friction heat to welding and an ultrasonic vibration terminal to apply ultrasonic vibration to welding tool.
Another one is the invention disclosed under patent application numbered KR2011073975A. The invention relates to friction stir point welding apparatus. The friction stir point welding device disclosed thereunder comprises a welding tool structured in rotatable form to pressurize a welding made from a preset combining material to apply friction heat to tune welding and an ultrasonic vibration terminal to apply ultrasonic vibration to welding tool. Spot welding is made by welding tool in partially overlapping welding.
Another one is the invention disclosed under patent application numbered CN103894721 A. Invention is a stir friction welding method with pre welding and post welding double ultrasonic synchronous vibration support. According to the method, ultrasonic wave is applied onto a welding joint in the welding process, stir friction welding is provided by help of pre welding and post welding double ultrasonic synchronous vibration, founder relation of a material is replaced with ultrasonic wave, resistance of material against deformation is reduced by ultrasonic vibration applied prior to welding, welding resistance exposed by stir cap during welding process reduces, welding speed improves, welding quality improves and applicable range of weld parameters increases. Grain thinning is produced in the material in weld joint area by ultrasonic vibration and high temperature applied after welding and mechanic feature of a connector is improved. By help of separate type design of stir cap and pole of an ultrasonic generator changing amplitude, failure of prevention of ultrasonic vibration by big down force of stir needle designed as integrated can be prevented. As a result, the need for a compress member containing vibration member eliminating the disadvantages available in the related art and inadequacy of existing solutions has necessitated development in the related art.
