Abstract

PROBLEM TO BE SOLVED: To set a pressure contact force generated at a welded connected part of works to be connected by welding to one another to a predetermined value. SOLUTION: An upper jig 1 is vibrated in a direction perpendicular to a pressing direction in the state that a lower jig 3 is urged toward the jig 1 to give a predetermined pressurized force to works 5, 7 set between the jigs 1 and 3, and a connecting part 9 of welding is welded by frictional heat. At this time, a pressure contact force at the part 9 is detected by a pressure sensor 21 provided in a receiving dowel 15 of the jig 3, and non-defectiveness or defectiveness of a product is decided according to whether the detected contact force falls within a predetermined range or not.

溶着方法。7. A pair of works to be welded and joined to each other is set between jigs arranged to face each other, and a predetermined joint is formed between the welded joints of the pair of works by the jig. In a vibration welding method in which the jig is vibrated while being pressurized by pressure to weld and bond the pair of works to each other, a pressing force at the welded joint generated by a pressing operation on the work by the jig is detected. A vibration welding method, wherein the pressing force on the work is corrected based on the detected pressure so as to attain a predetermined pressing force.
