Abstract
A metal pipe inner surface weld-mounting apparatus having a monitoring device is constituted by an arm, a horizontal torch, a mirror, a camera and a monitoring device. The arm has a supported base end portion, which is horizontally extended. The horizontal torch is attached to a leading end portion of the arm. The weld-mounting is performed on an inner surface portion of a metal pipe supported rotatably around a horizontally extending axis while at least one of the metal pipe and the horizontal torch is moved in a direction of the axis. The mirror is attached to the leading end portion of the arm. The camera is disposed in a position separated from the mirror for picking up an image of weld-mounting beads in a neighborhood of arc light of the horizontal torch through the mirror. The monitoring device monitors a condition of the weld-mounting.
