PROBLEM TO BE SOLVED: To provide a welding device which introduces a cylindrical member to a welding part in a state that both opposed end parts of the cylindrical member face to each other, continuously welds both of the end parts of the cylindrical member, discharges the cylindrical member from the welding part, and can correct welding strain.SOLUTION: The welding device includes: a first pressing mechanism 30 which presses a cylindrical member 10 so that a first end part 10a and a second end part 10b face to each other through a first spacer 38; a welding part 40 having a guide member 42 in which the cylindrical member 10 pressed by the first pressing mechanism 30 intrudes inside while being fed by the feeding mechanism 20, and which guides the cylindrical member 10 to a welding gun 44 while holding the cylindrical member 10 so as to maintain an opposed state of the first end part 10a and the second end part 10b through a second spacer 46; and a second pressing mechanism 50 which presses the cylindrical member 10 of which the first end part 10a and the second end part 10b are welded by the welding part 40 while being fed by the feeding mechanism 20. |
