一种搅拌摩擦焊焊接跟踪结构体
技术领域
本发明涉及一种搅拌摩擦焊焊接跟踪结构体。
背景技术
目前国际轨道交通业发展迅速，列车速度在不断提高，国内几家主要的轨道客车生产企业，铝合金车体均采用中空的挤压铝型材通过弧焊自动焊焊接技术制造，其长大焊缝焊接跟踪方法采用对坡口形式预先编制激光模板进行激光跟踪。目前铝合金车体采用熔化焊接方法，焊接气孔、热裂纹等缺陷已成为制约铝合金车体焊接质量和生产效率的焊接技术难题和瓶颈。鉴于搅拌摩擦焊方法的焊接效率高、焊接变形小、接头强度高于熔化焊接头且质量稳定，缺陷率低、制造成本较低，是一项高效、节能、环保的新技术，采用搅拌摩擦焊技术制造轨道客车铝合金车体已成为国内外发展趋势。采用搅拌摩擦焊技术焊接铝合金车体要求型材结构上无坡口，型材组对无间隙，焊缝跟踪多采用打点编程，此方法重复劳动、效率低。因此，寻求一种新的搅拌摩擦焊焊接跟踪结构体是解决搅拌摩擦焊长大焊缝自动跟踪的关键。
