摘要
TOPTIG是一种新的机器人焊接工艺,该工艺结合了TIG焊(焊接质量)和MIG焊(生产效率)的优点,其关键部件是一把独创设计的焊枪,填充焊丝穿过喷嘴与电极尖角平行。这种结构有一个重要的优点:减小了焊枪的总体尺寸,加强了机器人焊接时对于复杂焊接结构的可达性,无需借助机器人的第六轴改变焊枪及送丝的朝向。与该焊枪相关联的几个技术特征有:自动更换钨电极、双气流喷嘴和推拉丝送丝机构。该焊接工艺已经在汽车制造工业中得到实际应用,如使用CuSi3焊丝无飞溅焊接镀锌板;食品工业、金属装饰品或化工产品的其他应用,如焊接不锈钢或铝合金。
TOPTIG, a new robotic welding process has been developed which combines the quality of TIG welding with the productivity of MIG welding.The key part of the technology is an original torch design ：The wire feed is oriented in an angle close to the tungsten electrode traveling the gas nozzle.This configuration provides the advantage of reduced overall dimensions and enhanced accessibility of the torch for robotic welding of complex geometries.There is no need to direct the torch and wire feed towards the joint helps to liberate the 6th axis of the robot.Several technical features are associated to the new torch design such as an automatic electrode change, a double flow gas nozzle and a push pull wire feeder.The applications have been developed in partnership with automotive industry for the weld-brazing of galvanised steel with CuSi3 wire without spatter：Other applications can be found in welding stainless steel or aluminium ：food industry, manufacturing of furniture or chemical production.
