Fatigue property improvement blow processing equipment of welded joints, fatigue characteristics improvement methods and fatigue properties are improved the method of fabrication of welded joints

摘要

Also, without using a complicated mechanism, without a special position control, the weld metal tip striking pin to move in the direction of the weld line (3) the toe section (8) The present invention (9) direction It is an object of the present invention to provide a process and method for improving fatigue properties hitting processing apparatus of the weld joint that can move autonomously, Blow processing mechanism unit for performing a striking and processing (2), Support the pressing mechanism for pressing the weld toe blow pin supporting and blow processing mechanism section (5), Moving mechanism can be installed in the support pressing mechanism moves in the direction of the weld line (6) is disposed, Between the moving mechanism and the support pressing mechanism, and a (10) an angle adjusting mechanism for adjusting the angle formed between (7) Surface treated material axial centerline of the striking pin support or the pressing mechanism portion, Furthermore, the guerrilla mechanism that gives freedom to the movement of the welding direction perpendicular striking processing mechanism (4), I is disposed between the support and the pressing mechanism striking processing mechanism.
