ABSTRACT:
Corresponding edge faces of first and second blank materials disposed in a horizontal plane are aligned on a predetermined welding line. A positioning member is provided which comes in contact with and can be withdrawn from one edge face of the first blank material on the welding line. A base end of the first blank material is supported by a supporting mechanism, the vicinity of one end face of the first blank material is gripped by the first clamp, the first clamp withdraws from the welding line so as to cause the first blank material to buckle. In this state, the first blank material is pressed against the positioning member and fixed by a second clamp. In this way, the end face of the first blank material is precisely positioned on the welding line. After the withdrawal of the positioning member from the welding line, the second blank material is pressed against the first blank material until the second blank material is buckled. In this way the blank materials are brought into intimate contact without any gaps between them.
