文档介绍：焊接专业毕业论文题目建筑钢结构H型钢焊接专业焊接技术摘要本文主要针对钢结构制作当中所用到的H型钢焊接进行详细论述,由于钢结构的材料力学性能及特点决定着它的焊接性,所以在设计过程中必须选择合适的焊接顺序、焊接方法和焊接工艺参数。由于钢结构制作过程中大部分都是采用的H型钢焊接,翼板和腹板的拼接所采用的是埋弧自动焊,构件之间的连接主要是焊缝连接,所以焊接质量要十分重视。预防较长的H型钢在生产过程中产生变形,必要情况下采取二次矫正。最后对焊接过程中容易出现的缺陷进行分析,并提出有效的防止措施。关键词:H型钢翼板腹板焊缝连接AbstractThisarticlemainlyaimsattheHsectionweldingwhichthesteelstructuremanufactureusestocarryonthedetailedelaboration,becausethesteelstructurematerialsmechanicsperformanceandthecharacteristicaredecidingitsweldability,thereforemustchoosetheappropriateweldingcourse,,whattheliftingsurfaceandwebplatesplicingusesisburiesthearctoweldautomatically,ponentconnectionmainlyistheweldedjointconnection,,,:H-beamWingplateWebplateWeldconnection目录前言········································································1第一章绪论································································2第一节钢结构主要组成部分··············································2第二节H型钢的特点·····················································2第二章钢结构H型钢制作工艺·············································3第一节H型钢焊接主要焊接前准备·········································3一、开坡口双面焊·····················································3二、焊接收缩量加工余量的计算·········································3三、焊接H型钢组对···················································3四、H型钢定位焊接····················································3五、引弧板、收弧板的设置·············································4六、腹板厚度小于6mm,宽度大于600mm的反变形处理····················4第二节H型钢自动埋弧焊接工艺及变形控制·································4一、自动埋弧焊的焊接参数的确定·······································4二、焊接变形的控制············································
