Abstract
A resin end-face butt joint, a method for welding the joints, and a piping member ensure a sufficient clamping margin with the clamp of an ordinary welding machine, and ensure an appropriate distance between the centers even when joints having short tubular welding ring parts are welded. It is also possible to align the centers by positioning the centers along the same axis. The resin end-face butt joint includes multiple welding ring parts which communicate with a flow path within a joint base part and which are provided on the joint base part. Fastening parts are coaxial with at least one of these welding ring parts at the outer end of the joint for the purpose of clamping a welding machine.
