PROBLEM TO BE SOLVED: To provide a work arranging method in automatic welding equipment where all welding lines can be satisfactorily welded without increasing external moving apparatuses for a welding robot, and further, the installation space of the work can be reduced. SOLUTION: The work 20 is arranged in such a manner that its level difference joint welding lines 20a to 20d are tilted at a prescribed angle to a line 4 going from the terminal part of the arm 15a in a welding robot 16 toward the work 20. The welding line 20c is located inside the effective operation range 18 of a welding torch, and the welding torch can reach the whole length of the welding line 20c, e.g., by the extension-contraction function of the arm 16a, and there occurs no interference between the welding torch and a diaphragm 6. Also, regarding the welding line 20d, a satisfactory welding attitude can be secured similarly to the welding line 20c. Since the welding lines 20a and 20b are closer to the welding torch than the welding lines 20c and 20d, their satisfactory attitudes can be easily secured. COPYRIGHT: (C)2006,JPO&NCIPI
