Embodiment Construction

[0022] Exemplary applications of devices, systems and methods according to the present disclosure are described in this section. These examples are provided merely to add context and to aid in understanding the present disclosure. Thus, it will be apparent to one skilled in the art that the present disclosure may be practiced without some or all of these specific details. In other instances, well known process steps have not been described in detail in order to avoid unnecessarily obscuring the present disclosure. Other applications are possible such that the following examples should not be construed as limiting.

[0023] Friction stir welding is a method used to join two parts that may offer certain advantages over other forms of welding. For example, friction stir welding may not heat the parts being welded to as high an extent as other welding forms. As such, certain materials may not be able to withstand the temperatures associated with other forms of welding. Additio...

Abstract

A method for friction stir welding is provided. The method may include beginning a friction stir welding operation by directing a rotating friction stir welding tool along a joint between two parts. A temperature of the resulting weld may be measured. Thereby, a controller may adjust process parameters associated with the friction stir welding process to decrease a difference between desired and measured temperatures of the weld. The desired temperature may correspond to a temperature at which the parts are plasticized. The process parameters may include rotational speed of the friction stir welding tool, feed rate, axial force along the length of the friction stir welding tool, and tilt angle of the friction stir welding tool.

Description

technical field [0001] The present disclosure relates generally to friction stir welding, and more particularly to methods, apparatus and computer program products for improving the quality of welds produced by friction stir welding. Background technique [0002] Various methods and devices have been developed to combine the two components. Example embodiments of methods for joining two components include adhesive bonding, welding, use of fasteners, and the like. In the context of joining certain materials, such as metals, welding was identified as a suitable method currently used. [0003] Various forms of welding methods exist. Example embodiments of welding methods include laser welding, arc welding, gas welding, and friction stir welding. Friction stir welding may have certain advantages over other forms of welding. For example, friction stir welding does not involve heating the parts being welded to as high an extent as other forms of welding. In addition, friction...
