截齿座高速堆焊驼峰焊缝的工艺研究

Study on Hump-shaped Welding Process of Pick Box by High Speed Bead Welding

对机器人GMAG高速堆焊掘进机截齿座产生驼峰焊缝的焊接工艺进行了研究。根据生产节拍的要求,制定了焊接速度为120 cm/min。并在焊接电流、焊接速度不变的情况,仅通过改变焊接位置进行试验。试验结果表明,对于机器人高速堆焊截齿座环焊缝,采用下坡焊接方式有效地抑制了驼峰焊缝的形成。

Study on hump-shaped welding process of heading machine pick box by robot GMAG high speed bead welding. The welding speed is determined according the production takt.The experiment was carried out by welding position changed experiment result indicates that the downgrade ,based on invariable welding current and speed. The welding is favor to inhibit hump-shaped weld by robot high speed welded loop pick box.
