Provided is a welding machine for forming a tube, comprising a pair of fixing holders independently including a semispherical fixing groove which is equal to the outer circumference of a tube to be transferred, and surrounding the same, to easily transfer the tube without a supporting guide bar inside the tube, when the tube having a connection part connected after welding is transferred; an operating member having the fixing holders mounted to be in contact with the tube to be fixed, when the tube is transferred, and separating the same after transfer; and a repetition transferring member reciprocating the operation member to transfer the tube. Accordingly, the welding machine increases assemblability and economical feasibility, and stably and continuously transfers the tube without dent or transformation by simplifying the structure of a transferring part. |
