Abstract

One aspect of the present invention can include a friction welding method having a friction step for generating a friction heat by pressing the pair of works (W1,W2) while relatively rotating the pair of works (W1,W2), and an upset step started before generating an approach margin at the pair of works (W1,W2) at the friction step, restricting rotation of the pair of works (W1,W2) relative to each other and applying an upset pressure between the pair of works (W1,W2).

Description

[0001] This application claims the priority of Japanese Patent Application Nos. 2008-54581 and 2009-7790, the contents of which are incorporated herein by reference. Technical field [0002] The invention relates to a friction welding method and a friction welding device. The friction welding device is used for friction welding a pair of workpieces by pressing the pair of workpieces while rotating the pair of workpieces relative to each other. Background technique [0003] In the background art, various friction welding methods are known, for example, the known LHI method (refer to Japanese Laid-Open Patent Publication No. 2003-62676) and a method suitable for aluminum alloys (refer to Japanese Laid-Open Patent Publication No. H05-96385), etc. . According to the LHI method, frictional heat is generated by making the pair of workpieces abut against each other while rotating the pair of workpieces relative to each other. Further, the relative rotation continues until the friction to...
