18. GENERAL GUIDELINES FOR BUILD UP AND HARDSURFACING The steel used in Stanley LaBounty Saber Series shears is stronger and more durable than ever However this steel requires special attention during maintenance Pay special attention to the preheat and post heat instructions and follow them exactly Review the following guidelines for build up and hardsurfacing the shear Detailed instructions on maintaining specific areas of the shear are on the following pages Contact your Stanley LaBounty dealer or the Stanley LaBounty Customer Service Department for further information PREHEAT Preheat the general surrounding area to at least 200 100 to remove moisture from the base material Before ANY thermal process is applied to the shear steel including welding tack welding torch cutting and airarcing preheat the area within 6 150 mm of the local area to a minimum of 400 F 200 C and a maximum of 450 F 230 C This includes adding and removing lifting lugs Preheat must be uniform throughout the material thickness and maintained until all welding has been completed Avoid cyclic heating and large temperature swings Preheating may be done by localized gas torches or thermal strip blankets POST HEAT If preheat has dropped below 400 F 200 within 6 150 mm of the weld area post heat to 400 200 C and wrap with heat blanket to allow it to cool slowly to the ambient temperature Plan to perform build up and
