Zusammenfassung:PROBLEM TO BE SOLVED: To provide a welding method of a rippled web beam, a method capable of easily obtaining an improved welding bead appearance. SOLUTION: In the welding method of a rippled web beam for the purpose of performing fillet welding on a weld zone between a rippled web plate 12 and a flange plate 14 of the rippled web beam 10, the welding torches 23, 25 of two automatic welding means 22, 24 are arranged toward the same position nearly in the center of the parallel parts of the rippled web. Simultaneously, welding is started to advance the torches from the same molten pool to directions opposite to each other. Without stopping each welding arc, welding is performed through a circular arcuate part, an inclined part and the next circular arcuate part, upto the next parallel part E.
