Forging Industries Carver - 9525

Additional Details

PROCEDURE
Remove all defects; heat checks, spalls, and cracks. Preheat the unit to a minimum of 425 c. Maintain this temperature during welding . Utilize short arc length. Peening is necessary when filling in small cavities. Peen after depositing each pass. Peening is not necessary when welding large areas such as complete impressions except on the final pass. After welding , cool the unit still air to approximately 175 C. This is necessary to produce uniform weld hardness. When the cooling temperature is reached , immediately charge dies into a furnace at 560 C and temper for 12 to 16 hours. On rams and sow blocks, etc., stress relieve at 620 C for 12 to 16 Hours. Stress relieve hammer bases at 620 C at one hour per inch of thickness at temperature . Remove the unit from the furnace and cool in still air to room temperature
