  • Patent number: 4679722
    Abstract: A continuous and optimum weld is provided in the weld space between the attachment end of a secondary pipe and the outer surface of a primary pipe by means of a downwardly extending electric welding burner, the secondary pipe being oriented to extend at an angle to an imaginary central axis line extending through the primary pipe, by coordinating the vertical and horizontal positioning of the welding burner as the primary pipe is rotated, both around its imaginary central axis and end over end, so that the welding burner will be continuously aimed at the weld space and will operate at a constant current strength as the primary pipe rotates.

  • Patent number: 4323223
    Abstract: The cutting apparatus is used to cut a hole in a workpiece such as a pipe of relatively large thickness. The burner is mounted on a carriage which is reciprocated along a radially directed carrier which rotates about an axis perpendicular to the carrier. Reciprocation of the carriage is controlled as a function of the rotation of the carrier about the axis. In addition, a cam causes pivoting of the burner in accordance with the reciprocation of the carriage along the carrier. Operation of the apparatus is such that the tip of the burner is held at a constant distance from the surface of the workpiece. A motor is also provided for moving the burner longitudinally of its axis.
