Abstract
There are many expensive types of equipment in oil field on the sea from U.S.A or Europe in China. Some important components due to wear and erosion do not work; the large economic challenge needs laser recondition of the expensive parts. We have developed new laser cladding process for re-fabricating the long axle shaft and the body case in transferring oil pump in oil field on the sea. Using 5KW-CO2 lasers and the powder feeder, the cladding layer of NiCrSiB alloy on 40CrMo steel axle shaft with no crack and pores has been performed. The control distortion of long axle shaft during laser cladding has been researched. The laser re-fabricating has now been used to repairing production in the Bohai oil field in China.
