Inverter drive resistance spot welding machines are becoming a good choice of welding because of the increased machine efficiency and output power. The DC link capacitors in spot welding equipment store a large amount of energy. In case of any failure, the IGBT in the inverter has a risk of exhibiting a violent rupture. This rupture can damage the converter, drive down time and personal injury which may lead to the machinery certification problems. IGBT failure detection and solution for protection of these failures in resistance welding machines have not been reported in literature. Literature study of the IGBT failure, rupture, fault detection and protection has been carried out for inverter drives in power applications. On the basis of the findings some protection schemes and important measures in the design of the machine have been adopted which have resulted in the reduced risk of IGBT failure

An Investigation on fatigue crack propagation in gas metal and hybrid plasma-gas metal arc weldments of AA5083-H111 Okan, Kemal; Gürbüz, Rıza; Yurtışık, Koray; Department of Metallurgical and Materials Engineering (2015) 5083 aluminum alloy among 5XXX series has the greatest strength and is commonly used for its good weldability, corrosion resistance and moderate strength. In this study, 5083-H111 aluminum alloy plates were joined by Gas Metal Arc Welding (GMAW) and Hybrid Plasma Arc Welding (HPAW) techniques. Mechanical strength of base metal (BM) and welded samples was examined using hardness, tensile and toughness tests. Crack propagation behavior of BM, GMA welded and HPA welded samples was investigated by fatigue crack...
Comparison of Inverter Topologies Suited for Integrated Modular Motor Drive Applications Ugur, Mesut; Sarac, Hakan; Keysan, Ozan (2018-08-30) In this paper, various inverter topologies are compared for integrated modular motor drive (IMMD) applications. Two-level voltage source inverter (2L-VSI), three level voltage source inverter (3L-VSI) and series/parallel combinations of these topologies with system level modularity are compared in terms of voltage and current harmonic spectrum, passive component sizes and motor drive efficiency. New generation wide band-gap GaN power semiconductor devices are utilized in modular topologies and they are comp...
Analysis, design, and implementation of a 5 kw zero voltage switching phase-shifted full-bridge DC/DC converter based power supply for arc welding machines Uslu, Mutlu; Hava, Ahmet Masum; Department of Electrical and Electronics Engineering (2006) Modern arc welding machines utilize controllable high frequency DC/DC power supply with high dynamic and steady state current regulation performance. In the design robustness, small size and low weight, low complexity, and high efficiency are the defining criteria. The most suitable approach for a 5 kW arc welding machine power supply application is the high frequency Full-Bridge Phase-Shifted Zero Voltage Switching (FB-PS-ZVS) DC/DC converter with an isolation transformer. This converter not only gives the...
Fatigue Cracking of Hybrid Plasma Gas Metal Arc Welded 2205 Duplex Stainless Steel Yurtışık, Koray; Tirkeş, Süha (2014-01-01) Contrary to other keyhole welding applications on duplex stainless steels, a proper cooling time and a dilution were achieved during hybrid plasma gas metal arc welding that provided sufficient reconstructive transformation of austenite without sacrificing its high efficiency and productivity. Simultaneous utilization of keyhole and metal deposition in the hybrid welding procedure enabled us to get an as-welded 11 mm-thick standard duplex stainless steel plate in a single pass. Me examination on hybrid plas...
Determination of welding parameter dependent hot cracking susceptibility of 5086-h32 aluminium alloy with the use of mvt method Batıgün, Caner; Ankara, Osman Alpay; Department of Metallurgical and Materials Engineering (2005) Hot cracking is a serious problem that encounters during welding of aluminium-magnesium alloys. In the present study, solidification and liquation type of hot cracks in weld metal and the heat-affected zones of 5086-H32 aluminium alloy were investigated by using Modified Varestraint Test (MVT) with TIG-AC and TIG-DC welding. With determining the size, type and number of cracks, a relation was established between welding line energy and strain on the hot crack formation. This information was used to determin...
