METHOD FOR ANALYZING A WELDED CONNECTION WITHIN THE LASER

The invention relates to a method for analysing a welded connection during laser welding of workpieces (30a, 30b), comprising: detecting (S1) a first measurement signal (P1, P2) for process radiation generated during the laser welding; detecting (S2) a second measurement signal (P3) for the radiatio...

Zusammenfassung:	The invention relates to a method for analysing a welded connection during laser welding of workpieces (30a, 30b), comprising: detecting (S1) a first measurement signal (P1, P2) for process radiation generated during the laser welding; detecting (S2) a second measurement signal (P3) for the radiation reflected by the workpiece (30a, 30b); determining (S3) whether a gap (S) exists between the workpieces on the basis of the first measurement signals (P1, P2); and determining (S4) whether there is a welded connection on the basis of the second measurement signal (P3) when it is determined that there is a gap (S). 本发明涉及一种用于在激光焊接工件(30a，30b)时分析焊接连接部的方法，所述方法包括：检测(S1)用于在所述激光焊接时产生的过程辐射的第一测量信号(P1，P2)；检测(S2)用于被所述工件(30a，30b)反射的辐射的第二测量信号(P3)；基于所述第一测量信号(P1，P2)确定(S3)在所述工件之间是否存在缝隙(S)；并且当确定存在缝隙(S)时，基于所述第二测量信号(P3)确定(S4)是否存在焊接连接部。
