SELF CONTROL DRIVING STEEL PIPE WELDING EQUIPMENT BY WELD LINE TRACKING

摘要

The present invention relates to an autonomous steel pipe welding apparatus capable of tracking a weld line and, more specifically, to an autonomous steel pipe welding apparatus capable of tracking a weld line, in which a two-dimensional line scanner for projecting a two-dimensional line onto a welding part using a laser is installed to photograph the two-dimensional line projected onto the welding part using a CCD camera to read the two-dimensional line in order to accurately carry out welding as a welding torch is moved to track one edge of a groove formed on the welding part as a weld line.
