1引言我公司先后承接了秦山、岭澳、福清及方家山等多个项目的变压器油箱的制作加工:由于这些产品相对常规产品结构复杂,钢板拼接缝较多,而且涉及多处异种钢板拼接,很多可漏焊缝被加强筋或铜板扣压,单纯的依靠气压检漏不能有效保证产品在现场运行时不渗漏,为此,在选择技术高的焊工、严格控制焊接参数的前提下,针对油箱结构和制作特点,将无损检测技术、荧光检漏技术、振动吋效技术、气
1 Introduction Our company has successively undertaken the production and processing of transformer fuel tanks for many projects such as Qinshan, Ling’ao, Fuqing and Fangjiashan: due to the complicated structure of these conventional products, the splicing of steel plates is more, and the splicing of many dissimilar steel plates involves , A lot of leaky welds are stiffened or copper buckle, simply rely on the pressure leak can not effectively ensure that the product does not leak in the field operation, therefore, in the choice of high-tech welders, strict control of welding parameters under the premise of Fuel tank structure and production characteristics, non-destructive testing technology, fluorescent leak detection technology, vibration-efficient technology, gas
