Title:
WELDER FOR END OF TUBULAR PART FIXED INSIDE HOLE BORED TO SURFACE OF PLATE SUCH AS TUBE PLATE FOR STEAM GENERATOR
Document Type and Number:
Japanese Patent JPH01162570
Kind Code:
A
Abstract:
PURPOSE: To improve welding accuracy and quality by disposing an adjustable connecting assembly between a fastening means of a welding equipment and a welding head and making possible the connecting assembly to perform relative translational movement in relation to the fastening means and rotary motion around a specific axis. CONSTITUTION: A welding equipment is composed of a fastening means 12, a welding head 11, and an adjustable connecting assembly 13 by which the means 12 and the head 11 are connected. The connecting assembly 13 has a first supporting body 14 which is fixed to the fastening means 12, a sliding block 15 and a second supporting body 16, and, it performs relative rotational movements in relation to the fastening means 12 and the welding head 11. Furthermore, the fastening means 12 is relatively rotatably disposed around an axis 21 of the connecting assembly 13, and, the welding head 11 is rotationally driven around an axis 24. As accuracy of welding positioning of a repairing sleeve 7 and a plug 8 and movement of the head is improved thereby, welding accuracy and quality are improved.
