Material is EN36A or 8620 alloy steel with splined end fully hardened. Buttress end is left as soft as possible for later machining and welding. Machining is held true on all surfaces for setup. Ideal for use with precision splined hubs for manufactureing of M & F coplings. Stubwelds may also be used for replacing splined ends of worn shafts or manufacturing splined ends on new shafts.
Machine mated pilot registers and fillets true on both items to be joined. Hold firmly under press or between pressed centres. Preheat to electrode suppliers reccomendations. Use alternate welding deposits to fully fix parts then fully weld while rotating in a horizontal position. Some post heating may be neccessary to ensure slow cooling. Use only a special purpose electrode such as Staincraft or other comparable brand. Use a spray pack type splatter protection coating on spline area while welding. Check clocking error after welding to test alignment.
Above information is a guide only. Correct welding & machining operations are entirely the responsibility of the user.
