16、限公司引江济汉工程渠道11标工程项目部二一二年六月二十日止水铜片焊接工艺试验方案一、概述1、工程概况根据目前下发的设计蓝图,倒虹吸管身之间的伸缩 缝设置止水铜片。2、引用标准及编制依据1)设计施工图纸及相关的技术文件;2)水工建筑物止水带技术规范DL/T5215-2005;3)铜及铜合金带材GB/T2059-2008。3、止水铜片材质要求1)止水进场时应有工厂质量保证书(或检验合格证)。否则不得使用于本工程中。2)紫铜片止水厚度不小于1.2mm,抗拉强度不小于205Mpa,伸长率不小于20%,化学成分和物理力学性能满足GB/T2059的规定。二、紫铜片止水的焊接工艺铜止水连接采用双面搭接焊,搭
17、接长度不少于40mm,焊接宜采用黄铜焊条气焊,不应用手工电弧焊接。1、焊接准备1)主要机具设备:小型电焊机、乙炔、氧气及橡胶软管。2)材料: 紫铜片止水:必须有出厂合格证,进场后经物理性能检验合格后,方能使用。 黄铜焊条:按钢结构工程有关规定执行,焊条应分类、分牌号放在通风良好、干燥的仓库保管好,重要工程焊条,要保持一定温度和湿度(一般温度1015C,相对湿度小于5%为宜),焊条焊接前一般在2025C烘箱内烘干。初步选定焊条直径为5.0mm。2、作业条件1)焊工应经培训考核,持证上岗,熟识机械性能和操作规程。2)工作前或停工时间较长再工作时,必须检查所有气焊设备。乙炔瓶、氧气瓶及橡胶软管的接头
18、,阀门紧固件应紧固牢靠,不准有松动、破损和漏气现象,氧气瓶及其附件、橡胶软管、工具不能沾染油脂的泥垢,这样保证在气焊焊接的过程中不会因为气焊设备故障而导致意外发生。3)检查气焊设备、附件及管路漏气,只准用肥皂水试验。试验时,周围不准有明火,不准抽烟,避免引起火灾。4)氧气瓶、乙炔瓶与明火间的距离应在10米以上。如条件限制,也不准低于5米,并应采取隔离措施。5)气焊设备管道冻结时,严禁用火烤或用工具敲击冻块。氧气阀或管道要用40 的温水溶化;回火防止器及管道可用热沙、蒸气加热解冻。6)压力容器及压力表、安全阀,应按规定定期送交校验和试验。检查、调整压力器件及气焊设备安全附件,消除余气后才能进行。
