PANEL WELDING METHOD USING LASER POINTERS FOR ALIGNING PANELS TO WELD IN AUTOMATIC WELDING MACHINE

摘要

PURPOSE: A panel welding method using laser pointers is provided to obtain stable and accurate welding by aligning panels to weld and performing welding by using an automatic welding torch. CONSTITUTION: A panel welding method using laser pointer comprises the step of partial welding(22) of two panels(1) placed on a feed roll(21), the step of aligning an indication line(25) parallel to a welding line(23) with laser beam obliquely radiated from the five laser pointers(31), the step of checking if the welding line is aligned with a laser line(51), the step of moving the panels via the feed roll or placing the welding line under a welding torch head(50), and the step of automatically welding by the welding torch head moving horizontally along a frame(37).
