Abstract

PURPOSE: To orient the torch correctly to each welding point and fabricate a gutter top having sufficient strength, by disposing the probe of a limit switch close to the welding point of the constituent part of the grid, and correlatively moving the grid and torch and limit switch.
CONSTITUTION: A gride 1 having a sise plate 4 temporarily fitted to a flat bar 2 on the outermost side is placed on a conveyor 7 and conveyed. The grid 1 is determined in a correct position by a guide 10, and is brought to a welding part 6. When the flat bar 2 of the topmost part of the grid 1 contacts a limit switch 20, upper and lower torches 18 on the same side strike arcs between the upper and lower welding points of the flat bar 2 and the end of the torches 18 to weld them together. A timer is provided in the limit switch circuit, and if the operating time of the limit switch is longer than the determined duration, the torches 18 are connected to the power source securely for the specified welding time. When all flat bars 2 are welded to the side plate 4, a gutter top is completed.
