常用的碳棒有圆形和矩形两种,圆碳棒主要用于焊缝的清 根、背面开槽及清除焊接缺陷等,而矩形碳棒则用于刨除构件上 残留的临时焊道和焊疤、削除焊缝的余高和焊瘤及碳弧切割。常 见碳棒的型号和规格见表10-1,各种型号碳棒的额定电流见表 10-2。 表10-1 常见碳棒型号及规格

注:①操作时的实际电流值不超过额定电流值的±10%;

②操作时的空气压力为0.5~0.6MPa。

为了适应生产需要,碳棒的形状除以上几种外,还发展了管 状碳棒、多角形碳棒及自动碳刨用碳棒和交流用碳棒等,如图 10-6所示。

  图10-6 特殊形状碳棒、刨槽及选用电流

管状碳棒主要用于使槽底部扩宽;多角形碳棒用于一次刨削 欲获较宽或较深的槽道;用于自动碳刨的碳棒前端呈锥形,末端 一般有一段为中空形,专用于碳棒的自动接续;交流碳刨所用碳 棒的中心部分为稳弧剂,增加电流交变时电弧的稳定性。
