Numerical Analysis of Heat Transfer of Arc Welded Plate
In submerged arc welding process, the understanding of temperature distribution is essential in order to control the dimension of heat affected zone and to get the required weld bead shape and size etc. Moreover, the temperature profile is required to estimate the stress distribution in thermo mechanical analysis of the process. In this work, a numerical solution for moving heat source with Gau...
متن کاملFem Analysis of Truss Hollow Section Joint
Truss structures are widely used in construction of large-scale buildings. Design of steel structures is standardised in detail through set of European standards called EUROCODE. One of these standards, ENV 1993-1-8 deals with design of joints, but it does not cover the design of conical element for reduction of circular hollow section to the joint. Finite element method was used in this paper ...
متن کاملAnalysis of Cracks in the Pulsed Nd:YAG Laser Welded Joint of Nickel-Based Superalloy
The weldability of GTD-111 nickel-based superalloy by pulsed Nd:YAG laser welding with an average power of 250 W was studied, and the microstructural evolution and cracking characteristics were also investigated. The solidification cracking of the fusion zone (FZ) and the intergranular liquation cracking in the heat affected zone (HAZ) were observed in the joint. Solidification cracking was cau...
متن کاملTensile Properties of Ferrite-austenitic Welded Joint
Very often, in order to optimized welded constructions, some of their parts are made of heterogeneous steels. For example, microalloyed steels are in use for cars chassis making and high alloyed steels for different constructions making. From that reason, it’s not rare to find welded joints between ferrite microalloyed and austenitic highalloyed steels. As a rule, these joints are welded by usi...
متن کاملInfluence of gas tungsten arc welding parameters on the formability of aluminum tailor welded blanks
Welding method and its parameters has an important effect on the formability and mechanical properties of tailor welded blanks(TWBs). In this study gas tungsten arc welding(GTAW) is used to joint aluminum TWBs. Aluminum TWBs consist of 6061 aluminum sheets with different thickness of 1mm and 2mm. Main parameters of GTAW consist of welding current, pressure of shielding gas, welding speed and di...
