In the continuous path case, they might be used to track the desired weld path ahead of the welding torch.

在连续路径的情况下，传感器则用于跟踪测定焊枪按要求应经过的焊接路线。

Welding pose includes weld position and torch orientation, which is represented by weld slope, weld rotation, torch work Angle and traveling Angle.

焊接位姿包括焊缝位置和焊枪姿态，可以用焊缝倾角、焊缝转角、焊枪工作角和焊枪行走角四个参数来表征。

In the welding process, it is very important for welding torch automatically tracking the weld seam to assure welding quality and improve welding automation level.

焊接过程中焊炬自动跟踪焊缝对保证焊接质量，提高自动化程度有着极其重要的实际意义。
