in this paper, thermal effect of plasma arc welding is investigated, and temperature field of ferrite stainless steel is acquired. thermal effect of plasma arc and subsequently the generated temperature field in the work piece is the key for analysis and optimization of this welding process, which is the main goal of this paper. finite element simulation of welding process by simplec method and...
Optimization of Resistance Spot Welding Process Parameters for CR2 513 Material using Taguchi Method
Gas tungsten arc welding (GTAW) or Tungsten inert gas welding (TIG) is one of the widely used techniques for joining ferrous and non-ferrous metal.Gas tungsten arc welding process,consist of non-consumable tungsten electrode which is used to provide the arc for welding. During the welding cycle a shield of inert gas expels the air from the welding area and prevents oxidation of the electrode, w...
Objective: The welding process involves metal ions capable of causing cell lysis. In view of this fact, the aim of this study was to test the hypothesis that cytotoxicity is present in different types of alloys (CrNi, TMA, NiTi) commonly used in orthodontic practice when these alloys are subjected to electric spot welding. Methods: Three types of alloys were evaluated in this study. Thirty-six ...
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. ...
Purpose: This study aims to examine the interaction between process parameters and bead geometry, to perform the research to predict optimal bead geometry (bead width, reinforcement height, left leg length, right leg length) through the analysis of experimental data. For this, not only linear and the curvilinear equations were developed to predict bead geometry, but also interactions between pr...
The aluminum alloys of Al1050 with thickness of one millimeter and Al3105 with thickness of half millimeter were joined via ultrasonic spot welding (USW). To create a suitable welding, a vibrating horn (welding tool) fit to transducer and ultrasonic generator was designed using ANSYS software. Due to mechanical and thermal cycles during USW, both diffusion and mechanical mixing facilitated the...
