1、T9l／P9l钢焊接工艺导则关于颁发《T9l／P91钢焊接工艺导则》的通知电源质[2002]100号各省(市、区)电力公司：近几年来引进机组主蒸汽管道及再热热段管道普遍采用了P91钢，国内300MW及以上机组也普遍开始采用了这种钢材。为了指导施工，保证火力发电设备安装、检修的焊接工程质量，我部以国家电力公司原火电建设部颁发的T91／P91钢焊接工艺暂行规定为版本，结合近年来的实践经验进行了修订，定名为《T91／P91钢焊接工艺导则》。现予以颁发，请各单位遵照执行。附件：T91／P91钢焊接工艺导则国家电力公司电源建设部二OO二年十月三十日1、制订依据本导则是根据电力工业焊接
2、有关规程、规范、技术条件和相关资料，以国家电力公司火电建设部制订的“T91／P91钢管焊接工艺暂行规定”为版本，结合近年来积累的实践经验进行修订。2、适用范围2．1本导则适用于火力发电设备，以T91／P91钢管及与其它钢种相连接的各类焊接接头的制作、安装、检修工程的焊接工作。2．2适用于手工钨极氩弧焊和焊条电弧焊的焊接方法。3．总则3．1T91／P91钢的焊接工艺评定，应遵守SD340—89《火力发电厂焊接工艺评定规程》的规定，并以工艺评定为基础确定焊接工艺，编制作业批导书。3．2焊接T91／P91钢焊工技术能力的验证，应按DL／T679—1999《焊工技术考核规程》的规定
3、考核，取得合格证书后，方可参加焊接工作。3．3焊接接头质量检验应遵照DL／T820—2002和DL／T821—2002两本检验规程的规定进行，其质量标准应符合DL5007—92规定。povertyalleviation,makingstablepovertyofvillageandexitinatimelymanner,shouldsupportpovertyalleviationinto,fromthe...Thestabilityoffamilies,notsimplyoneoff,notonlyto"helpahorse",and"givingalift"toprev
