Abstract

The head is carried by an arm aligned at 90 degrees to the longitudinal axis of the seam and mounted on a trolley driven along the seam. On the head, and is front of the burner, is a feeler finger travelling along a chamfer forming part of the seam; and the finger is connected to a servo-circuit employed to adjust at least one welding parameter. The head is driven along its carrier arm to ensure that the burner is always aligned on the centre of the seam; and the servo-circuit controls the speed of the trolley so the correct amt. of filler metal is deposited at all points along the seam. Pref. appts. includes a second feeler finger mounted alongside the burner and used to monitor any change in the longitudinal curvature, i.e. the height, of the seam. Useful in making 90 degrees joints on plates 20-30 mm thick.
