Abstract
PURPOSE: To form a welded joint of good quality with superior working performance by forming a groove into the narrow shape having a root gap of a specific angle and performing gravity welding by using a coated electrode in three o'clock butt welding of steel plates.
CONSTITUTION: Steel plates 1, 1' are butted in a three o'clock position, and a root gap G1 is taken at θ1≥θ2 in the angle θ1 formed by the top surface 15 of the groove of the plate 1 and the angle θ2 formed by the bottom surface 16 of the groove of the plate 1', so that the insertion of an electrode 10, and guiding and moving of an arc generating point are effected smoothly and the removal of the slag is facilitated. A steel backing strip 18 is provided to the rear of the groove, and a steel plate for preventing drooping is mounted as a guide to the groove. A welding carriage 4 is suspended by means of a guide roller 3 and a retaining roller 3' to a hand rail 2 provided on the material 1, and an electrode holder 9 is mounted to a universal joint 6 and a slide bar 7, then gravity welding is accomplished with a long sized covered electrode 10.
