ABSTRACT:
An apparatus for automatically a pair of welding tubular components made of a thermally fusible resin by abutting them to each other, includes a pair of clamp units for holding the pair of tubular components, an abut portion on which the end face of each of the tubular component abuts when the pair of the tubular components are held by the pair of clamp units, a cutting unit for cutting respective end faces of the pair of the tubular components held by the pair of the clamp units so that the cut end faces are normal to the axis of the pipes, and a fusing unit for fusing opposing end faces of the pipes which are cut by the cutting unit, to an equal fusing depth. The cutting unit, the abut portion and the fusing unit are spacedly disposed on a rotary disc in an angular moving direction. One of the tubular components is moved toward the other of the tubular components which are fused by said fusing unit for welding them to each other.
