| Abstract: | Arc sensing is an important seam tracking method.To satisfy the need of seam tracking for narrow gap rotating arc welding,the average method of arc sensing is studied.First,the proper interval for deviation signal extraction is studied by two proposed evaluation criteria.Then considering the anti-interference capability,a number of rotating cycles are considered in one comparison.The experiment result showed that this method can satisfy the need of narrow gap rotating welding. |
