【正文】 Welding electrodes, fluxes, wires and flux cored welding wires whose storage life expires may be distributed for use only after they pass reinspection organized by relevant functional departments.Reinspection is generally aimed at checking if any defect likely to affect welding quality occurs to welding materials, and is usually limited to exterior inspection and process performance test. If there is any about service performance of welding materials, necessary inspection items may be included.The specified period is any of the following periods of time as from the date of production:a) Period as remended in quality certificate or specification of welding material supplier。c) The storage life of welding materials with ordinary packing and other welding materials is two years. 受潮、變質(zhì)的焊接材料對(duì)于嚴(yán)重受潮、變質(zhì)的焊接材料，應(yīng)由質(zhì)檢和有關(guān)職能部門進(jìn)行必要的檢驗(yàn)，并作出降級(jí)使用或報(bào)廢的處理決定之后，方可準(zhǔn)許出庫。 Dampened, deteriorated welding materialsFor severely dampened or deteriorated welding materials, quality management and relevant functional departments shall make necessary inspection and decide on concession or scrapping before such materials may be taken out of warehouse. The flow direction of those materials must be strictly controlled.9 使用過程中的管理 一般要求 車間應(yīng)設(shè)置專門的焊接材料管理員，負(fù)責(zé)焊接材料的焙烘、保管、發(fā)放及回收。9. Management during use General requirements The workshop shall have a welding materials management clerk who is responsible for drying, custody, distribution and recovery of welding materials. Responsibility for use and managementProduction supervisor in the workshop assumes overall responsibility for management and use of welding materials。烘干、保溫設(shè)施應(yīng)有可靠的溫度控制、時(shí)間控制及顯示裝置。 焊接材料在烘干及保溫時(shí)應(yīng)嚴(yán)格按有關(guān)技術(shù)要求執(zhí)行。堆高不超過70mm。 不同類型的焊接材料應(yīng)分別烘干，避免混雜。焊接材料的烘干規(guī)范可參照焊接材料說明書的要求確定。 焊接材料管理員對(duì)焊接材料的烘干、保溫、發(fā)放及回收應(yīng)作詳細(xì)記錄，達(dá)到焊接材料使用的可追溯性。 真空包裝焊接材料采用真空包裝，按照焊接材料制造商技術(shù)規(guī)格書的規(guī)定，允許不進(jìn)行焙烘的焊接材料，可直接使用，但必須在 4 小時(shí)內(nèi)用完，或嚴(yán)格按照焊接材料制造商技術(shù)規(guī)格書的規(guī)定發(fā)放和使用。 After drying, welding materials shall be kept within a specified temperature range. Welding materials management clerk shall record in detail the drying, heat insulation, distribution and recovery of welding materials to ensure the traceability of welding materials usage. The surface of welding wire must be smooth, tidy and free of oil, rust or filth. Welding materials with vacuum packingIf vacuum packing is adopted, welding materials that are allowed not to be dried according to technical specifications of the manufacturer of welding materials may be directly used but must be used up within 4 hours, or shall be distributed and used in strict accordance with the said technical specifications.If storage life expires or vacuum packing is damaged, welding materials may not be used. 識(shí)別標(biāo)志在使用過程中，應(yīng)注意保持焊接材料的識(shí)別標(biāo)志，以免發(fā)生錯(cuò)用、混用，造成質(zhì)量事故?；厥盏暮附硬牧蠎?yīng)滿足下列條件：a) 標(biāo)記清楚；b) 整潔，無污染。b) Tidy and unpolluted. 回收的焊接材料的烘干焊接前要求必須烘干的焊接材料(堿性低氫型焊條及焊劑)，允許回收后再次烘干，但對(duì)烘干溫度超過 350℃的低氫材料，累計(jì)的烘干次數(shù)不超過 3 次。 Dry of recovery welding materialsWelding materials that must be dried before use (., alkali lowhydrogen welding electrodes and fluxes) may be dried again after recovery. However, lowhydrogen materials that shall be dried above 350℃ may be dried for at most 3 times. Repeated use of welding fluxWelding flux may be used repeatedly, provided that:a) Used welding flux is mixed with new welding flux of the same batch and the mixing ratio of the former is below 50%. For an important product, the mixing ratio of used welding flux is preferably around 30%。c) The granularity of mixed welding flux meets the specified requirement.10. 支持性文件 Supportive Procedures無N/A11. 附錄 Appendix無N/A
