Welded article and method of making same |
摘要 |
A cam follower having a two-piece composite laser welded configuration is disclosed and comprises a solid and alternatively thin wall tubular base (16) portion formed of mild steel and a thin-disc reaction portion (18) having a hardened, wear resistant outer surface portion (50). The reaction portion is joined to the base portion by laser welding which results in a weld zone (54) comprised of a fusion zone (56) bounded on either side thereof by heat affected zones (58) having relatively narrow transverse thicknesses. A method of laser welding the hardened reaction portion to the mild steel base portion is also disclosed.
