Identification of Laser Weld Penetration Based on Fuzzy C-means algorithm
Weld penetration is an important standard of welding quality identification.This paper proposes a weld penetration status identification method based on the high-speed visual detection and fuzzy C-means algorithm (FCM).In a fiber laser butt-joint welding of Type 304 austenitic stainless steel plate with a high power 6kW continuous wave fiber laser,an infrared sensitive high-speed video camera was used to capture the dynamic images of the molten pools.Molten pool characteristic parameters were extracted by image processing,and those parameters were used to identify the weld penetration status with FCM.Experimental results showed that the weld penetration status could be evaluated by the molten pool images during fiber laser welding.
