Abstract
A plastic tank is comprised of two parts, a base and a top, that are permanently joined to each other by welding at a circumferential joint formed by two mating flanges of the parts. Fusion weld elements are captured on the faying surfaces of the flanges of the assembled parts, and the elements melted by internal heating of metal portions of the elements. Before heating of the elements, the flanges are gripped by a clamp which applies a resilient force which, during welding, causes the flanges to move toward each other and thereby a good weld joint is formed.
