Research on the Accuracy Method of Analyzing Welding Wire Samples Using OBLF Small Sample Fixtures
The sample preparation and analysis method of welding wire ER70S-6 was studied by OBLF direct reading spectrometer(OBLFQSG750-Ⅱ).By using the small sample jig of OBLF,the welding wire samples prepared by different methods were stuck in the jig and placed horizontally on the spark table for analysis,and the best analysis conditions were found.The analysis results were compared with those of infrared carbon sulfur analyzer(CS-230)and inductively coupled plasma spectrum analyzer(ICPAESPQ9000),which solved the problem of long time for traditional chemical analysis of welding wire.
