摘要
根据铝合金桁架铝合金管材与接头环缝焊接要求,设计并制造了一台专用焊接设备。根据焊接时序要求,采用可编程控制器实现对焊接设备逻辑顺序的控制,并制定了铝合金桁架铝合金管材与接头环缝的惰性气体保护焊MIG自动焊接工艺。结果表明,该焊机自动化程度高、性能稳定、操作简便,能够满足铝桁架铝合金管材与接头环缝自动焊生产要求,同时提高了生产率。依据制定的焊接工艺,进行了焊接试验。焊接试验表明,制定的工艺所获得的铝合金桁架铝合金管材与接头对接接头,满足焊缝质量要求。
According to the requirements of aluminium alloy boom circumferential welding,this paper design and manufacture a special automatic welding equipment.In terms of weld time sequence requirement,PLC is used to implement the control of welding device logical subsequence.besides,work out the MIG automatic welding procedure of circumferential welding.The Result shows that the welding device displays high degree of automation,stable performance and convenient movement,which could satisfy production requirements of aluminium alloy boom automatic circumferential welding and improve productivity.Based on the welding procedure, welding experiment is done.The result indicates that welding procedure could reach the quality requirements of welding joint.
