This paper reports the applicability of fuzzy logig (FL) to predict the hardness of melt zone (HMZ) during the gas metal arc welding (GMAW) process, which is affected by the combined effect of ZrO2 nano-particles and welding input parameters. The arc voltage, welding current, welding speed, stick-out, and ZrO2 nano-particles were used as the input parameters and HMZ as the response to develop F...
An ER430LNb ferritic stainless steel wire was used for a gas metal arc welding (GMAW) test. The characteristics of droplet transfer and its corresponding voltage current waveforms were investigated using high-speed camera synchronous acquisition electrical signals. weld formation, patterns microstructures under different parameters observed, the effect level on frequency discussed. As results s...
A two dimensional mathematical model has been developed for describing the temperature, flow, and electric fields in the are column of the Gas Metal Arc Welding (GMAW) of aluminum in argon shielding gas using axisymmetric Navier-Stokes, Maxwell, and differential thermal energy equations. The predicted results are most sensitive to the cathode spot radius and an optimum cathode spot radius exist...
Hybrid Layered Manufacturing (HLM) combines the benefits of both subtractive and Additive Manufacturing (AM). In this paper authors did characterization of AM components by using Kernel Average Misorientation (KAM), Electron Backscatter Diffraction (EBSD) and hardness tester. The main focus is on matrix integrity during Gas Metal Arc Welding (GMAW) deposition and surface quality during machinin...
Bu çalışmada paslanmaz çeliklerin pulse (P-GMAW) ve double (DP-GMAW) kullanılarak gazaltı MIG (Metal Inert Gas) yöntemi ile birleştirilmesi araştırılmıştır. Kaynaklı birleştirilmelerin mekanik özelliklerini belirlemek için sertlik ölçümü, çekme deneyi mikroyapıda oluşan değişiklikleri tespit etmek amacıyla mikroyapı çalışmaları incelenmiştir bu testler sonucunda kaynak yönteminin diğer yöntemle...
Offshore building construction is inseparable from the fabrication process. Fabrication process that has an important role in terms of engineering, material repair and welding In offshore construction, a precise method needed on A36, where A36 steel one main materials buildings. this study comparison results GTAW, GMAW, FCAW against Tensile Test Macrostructure Test. The research show best tensi...
Gas metal arc welding (GMAW) is a highly efficient and fast process for fabricating high quality weld. High quality welds are fabricated by proper selection of consumable includes gas and filler metals. The optimum flow rate of gas will ensure the proper quality of weld. In this project, a fluid flow behavior of different flow rate is modeled and the change quality will be studied. KeywordsHydr...
The use of the welding process on an industrial scale has become significant over years and is currently among main processes for joining metallic materials. Along weld, structural changes occur in vicinity joint. These thermal stresses geometric distortions are mostly undesirable complex to predict with precision. Using S235JR steel as base material, laboratory experiments were carried out usi...
