ABSTRACT:
When a weld area of weld surface between a flange portion3aof a pipe3and a flange portion4aof a pipe connection member4is S and total energy consumed on the weld surface is Et, ultrasonic welding is carried out to produce said ultrasonic weld assembly in such a manner that an energy density E defined as the quotient obtained by dividing the total energy Et by the weld area S satisfies the relation 26.69e−0.3708P<E<240.9e−0.1445Pwith a surface pressure P on the weld surfaces of the flange portion3aand the flange portion4a. Preferably, ultrasonic welding is carried out in such a manner that the energy density E satisfies the relation 133.45e−0.3708P<E<240.9e−0.1445P.
