A study of the Friction Stir Welding (FSW) process was carried out in order to evaluate the influence of process parameters on the mechanical properties of aluminum plates (AA5754-H111). The process was monitored during each test by means of infrared cameras in order to correlate temperature information with eventual changes of the mechanical properties of joints. In particular, two process par...

Primljeno (Recieved): 2011-07-13 Prihvaćeno (Accepted): 2011-11-15 Original scientific paper This paper presents welding current influence on spreading of electromagnetic field in TIG welding process. The quality of welding is analyzed by „Fast Fourier Transformation“ (FFT) on recorded current. Electric and magnetic field are measured using an instrument „Macshek ESM – 100 3D Fieldmeter“ [1]. W...

Welding is an important process used in the iron based industries. About two percent of the working population is engaged in some type of welding. The procedure of welding is simple but its health implications are complex. Welding generates enormous amounts of gases and metal fumes. Depending on the substrate and welding type, the composition of resultant gases and fumes changes. Therefore, wel...

Rail thermite (or Thermit) welding is a valuable welding technology for the railway industry because of its simplicity, portability, and economy. Using the finite-element method, a heat transfer analysis is conducted in this study. Only the heat transfer by conduction was simulated explicitly in the model, the other thermally significant phenomena were included through the boundary and initial ...

In ultrasonic welding, high frequency vibrations are combined with pressure to join two materials together quickly and securely. Ultrasonic welding can join dissimilar metals in a split second, ultrasonic welding eases problematic assembly and this cost effective technique may be key to mass producing fuel efficient. In this work effect of various parameters on weld strength have been studied. ...

In industries and research organizations most widely used welding methods are shield metal arc welding (SMAW), gas metal arc welding (GMAW), gas tungsten arc welding (GTAW) and submerged arc welding (SAW). The SAW process is often preferred because it offers high production rate, high melting efficiency, ease of automation and low operator skill requirement. This review will be very helpful for...

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...
