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.
