Abstract

A heat-weldable weld fitting that has a cylindrical fitting main body portion. The cylindrical fitting main body portion includes an outer periphery including a first end portion, a second end portion, and a middle section between the first end portion and the second end portion, and positioning scales formed at equal intervals in a peripheral direction of the second end portion of the outer periphery of the fitting main body portion. The first end portion being configured to be heated by a heater and is welded to an end portion of another weld fitting. The positioning scales are configured to define an angular portion of the weld fitting relative to the welding apparatus at the time of welding the first end portion to the first end portion of another weld fitting by matching the positioning scale with a reference mark provided on the clamp portion of the welding apparatus.
