Ultrasonic Testing of Spot Welds in the Automotive Industry
نویسنده
چکیده
In the modern motorcar production, more than 300 deep-drawn sheet metal parts are joined together by more than 3,000 spot welds on each car body. To check the spot welds within the framework of the quality assurance, different nondestructive test methods are available in addition to the destructive methods (tear down test, metallographic inspection): the chipping test and the ultrasonic test, with the ultrasonic test becoming more and more important because, firstly, the chisel test is “not totally nondestructive” and, secondly, the ultrasonic test ensures a clearly higher test reliability [1].

Analysis of Resistance Spot Welding Process Parameters Effect on the Weld Quality of Three-steel Sheets Used in Automotive Industry: Experimental and Finite Element Simulation
In the present research, the effects of spot-welding process parameters on the nugget diameter and electrode penetration depth of spot-welded joints were investigated. To achieve this, a spot-welded joint of three-thin sheet low carbon steels (same thicknesses of 0.8 mm) was simulated as an electerical-thermal-mechanical coupling of 3D finite element model. After validating the finite element s...
