ABSTRACT:
A composite article having particular utility as a welding stud and a process for producing the article. The article is comprised of a pin and an enclosing member formed from a dissimilar material. The pin is comprised of a head and a shank. The pin is formed from a metal. The cross-section of the head is larger than that of the shank in a direction normal to the length of the pin. The enclosing member fits over and is adhered to the shank. The enclosing member is formed from material in powder form. It is placed upon the shank and sintered thereon. The enclosing member fits up against the head so that the article is substantially devoid of a gap therebetween. The absence of a gap is attributable to the shape of the shank. The cross-section of the shank is larger, in a direction normal to the length of the pin, adjacent the head than over other parts thereof.
