Abstract
When a weld area of weld surface between a flange portionof a pipeand a flange portionof a pipe connection memberis 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<E<240.9ewith a surface pressure P on the weld surfaces of the flange portionand the flange portion. Preferably, ultrasonic welding is carried out in such a manner that the energy density E satisfies the relation 133.45e<E<240.9e.
