Research on Surfacing Welding and Machining Process of Large Valve Corrosion Resistant Layer

Abstract:

The corrosion resistance layers can be surfaced in the valve casted by carbon steel, to enhance the corrosion resistance performance. By the 3D solid model, the weight and internal area of valve body was obtained. The surfacing process was designed and the welding rods theory amount was calculated. And the actual amount was close to the theory one. The surfacing and cutting process was designed for the fit surfaces and the dimension chain was calculated to meet the fit accuracy and the corrosion resistance layer thickness. The results show that it has the engineering significance by using 3D solid model to estimate the producing costs; the fit accuracy and the corrosion resistance layer thickness can be obtained together based on the surfacing and cutting process; in this way, the cost can be cut down more than 30%, compared the whole stainless steel valve.
