ABSTRACT:
Two arc tubes which are to be connected are held at different levels. Predetermined portions in the vicinity of an end of each arc tube are evenly heated and softened by a flame of a burner from the side. An air flow is supplied to blowing up the softened portion to form a semi-junction bridge having a circular cross-section and a flat connecting face. The thickness of the wall of the semi-junction bridge is even. The arc tubes having the semi-junction bridges are disposed on the same plane and one arc tube is moved to the other to connect the semi-junction bridges while the connecting faces are softened.
