RAPID焊接工艺技术在箱型梁翼缘板焊接的应用

摘要

RA PID焊接技术是目前比较先进的一项焊接工艺技术，它是利用数字控制的电弧曲线参数，进一步压缩电弧，使得电弧热量更集中、更具备熔透能力的一种高速焊接技术。由于其高速、高熔深的焊接工艺特性，被用于单面焊接双面成型的钢结构焊接上，可显著提高焊接生产效率。在铝电解多功能机组生产制造的专业厂，其天车主梁的焊接工艺技术一直是采取MAG焊接工艺技术，焊接质量及效率低。应用RAPID焊接工艺技术对箱型梁翼缘板焊接，与M AG焊接工艺技术在焊接质量、效率、经济性等方面进行对比、分析总结，可知，RAPID焊接工艺技术应用在天车主梁翼缘板的焊接中，综合经济效益较MAG焊接工艺有着显著的提高。%RAPID welding technology is an advanced high speed welding technology , the arc curve parame‐ters of w hich is controlled by digital technology , further compressed arc made the arc heat more concen‐trated , and had more penetration ability . Because of its welding technology properties of high speed and high penetration ,it is used for steel structure which is single -sided welding but double -sided molding , significantly improved the efficiency of welding production .In most aluminum electrolysis multifunctional unit manufacturing plants , the crane girder welding technology has been adopt MAG welding technology , welding quality and efficiency is low . After comparing , analyzing and summarizing the welding technology between RAPID and MAG about welding box beam wing flange , found that the RAPID welding technolo‐gy is better than MAG in welding quality , efficiency , economy and so on . RAPID welding technology used in crane girder flange plate welding , the comprehensive economic benefits is significantly improved than that of MAG welding technology .
