1. 焊材库办理员具有要求
焊材库办理员应具有以下要求:①焊材库应装备专职的焊材库办理员,并具有必定的焊接专业知识,熟知各种焊接资料的功能、用处和储存办法。②了解本公司焊材一级库和二级库的办理要求,并按两库的办理制度进行办理。③对库区的物品坚持清洁、整齐。④上、下班时注意对焊材库各电源的敞开与切断事项。⑤把握焊条烘箱的运用和维护等技术。
2. 焊材一级库设置要求
焊材一级库设置应满意以下要求:①焊材一级库应具有关闭、枯燥、通风等条件,仓库内应装备除湿机、红外线加热器、温湿度计及必定数量的货架。②一级库区设合格区、待验区、不合格区,并有显着的标志和分界。
一级库的设置需依据各当地的气候环境及企业实际状况进行,全体上需保证内部环境枯燥、整齐,红外线加热器首要适用于冰冷区域,温湿度计每天需记载仓库的温度及湿度,以便当地特检院人员查看,且温湿度计需求有资质的查验单位进行校验。
3. 焊材入库要求
焊材入库要求如下:①焊材有必要具有有用的质量证明书,不然不予验收。②焊材入库前按查验方案的要求,采用随机抽样的方法进行外观查看,发现有下列条件之一的有必要退货,并加以记载:焊条药皮决裂掉落过长(>15~20cm);焊条药皮上无商标;焊丝严重蜕变;焊条或焊丝受潮严重;端部无标志;与包装类型不符。
焊材入库前需查看相应的质量证明书,无质量证明书者或焊材上端部的标志与质量证明书不一致者一概退货,入库时先放入待检区,并按以上要求进行查看。
4. 焊材一级库办理要求
焊材一级库办理要求如下:
榜首, 按“资料入库单”填写物资到货记载和进货查验记载,有复检要求的填写“理化试验委托单”,委托有关单位复检,对合格入库的焊材及时树立“资料台帐”。
第二,入库焊材应分层摆放在距地上300mm以上的架位上,与墙面坚持300mm以上间隔,以保证空气流通。
第三,入库焊材应按不同的类型、标准、批号分类摆放整齐,并按质量证明书内容进行标识。禁止将不同类型、标准、批号的焊材混放在一起。
第四,办理员应坚持仓库的环境卫生、坚持枯燥且通风杰出,温度操控在5℃以上,湿度坚持在60%以下,每天迟早照实填写“温湿度记载表”。关于详细的操控温度、湿度规模可依据当地特检院要求进行。
第五,随时对焊材库进行盘点。常常查看仓库内设备的运用状况,以保证其正常工作;随时查看焊条的储存质量状况,以防蜕变。发现受潮、污损和寄存期两年以上的焊条须经焊接责任人断定查验项目进行复验,并契合相关要求时方可发放,不然禁绝发放。发现过期或质量有问题的焊材经焊接工程师查看并认可后可用于非承压、非受重力部件。
第六,焊材二级库从一级库取焊材时,准则上按出产所需的数量和焊接工艺规则的定额,领取车间当天所需用量,办理员发料时对同种类、同标准的焊材应遵从“先进先发”的准则。发料后在收发卡上挂号领料单号、领料日期、发放数量、类型及标准等。
第七,除焊材库办理员外,其他人员不得进入一级库取用焊材,而且一级库的焊材需经二级库按规章制度处理才干进入车间出产。
第八,焊材库办理员依据出产方案要求定时了解一级库焊材库存量,并向焊接工程师反响状况,由焊接工程师提出收购要求。
5. 焊材二级库办理要求
(1)焊材二级库设置 焊材二级库应具有关闭、枯燥、通风等条件,仓库内应装备烘焙箱和保温箱、保温筒和必定数量的货架。烘焙箱和保温箱上的温度指示器需有资质的查验单位进行校验。
(2)焊材烘干 榜首,用于重要结构管道和容器的焊材(焊条、焊剂)有必要烘干,焊材烘焙人员应每天和出产部门进行交流,依据车间出产需求进行烘焙,并有20%的余量,以保证出产所需,出产中暂不必的焊材应及时退回一级库保管。
第二,在焊材烘焙前应注意查看烘焙设备是否正常工作,烘箱的温度指示是否活络正常。
第三,焊材烘焙时应按焊材查验编号(批号)、类型、商标及标准进入烘箱内分格烘焙,不同查验编号(批号)的焊材之间应作好标识不得混杂。每层焊条堆积不能太厚(一般1~3层),避免焊条烘干时受热不均和潮气不易扫除。不锈钢与碳钢焊条,以及不同烘焙温度的焊条,不得在烘焙箱内一起烘焙。
第四,焊条和焊剂烘焙时,应严格按焊材烘焙表(见附表)进行,烘焙后的焊条或焊剂应在烘箱的温度降到100~150℃时,移至100~120℃的保温箱内寄存。
焊条或焊剂烘焙后在烘箱降温取出时不得将烘箱密封门翻开降温,应以切断烘箱电源翻开排气孔的方法天然降温到100~150℃。关于多天搁置保温箱内的焊条或焊剂,烘焙人员应与出产负责人交流,断定必定时刻内搁置的焊条或焊剂应从保温箱内取出,按标准、类别转移至一级库并贴上标签、注明烘焙记载。记载内容包含:焊材商标、标准、入库查验编号、数量、烘焙时刻、烘焙温度、保温温度和日期等。
