The paper "The behavior analysis of bolted end-plate connections under static load by using finite element method" investigates the mechanical behavior of bolted end-plate beam-to- column connections with changes of thin of end-plate and size of bolts under bending moment. The finite element models are generated in ANSYS software, in specially all of meshes are hexahedral meshes as well as be continuous at welding. The results obtained from this study are validated based on three factors: loading capacity, moment resistance and joint rotation.

The paper "A Report of narrow gap welding" presents experimental results of narrow gap butt welding of steel plates with greater thickness by using the Metal Active Gas (MAG) welding method. The mechanical properties of the welding joints were examined by metallographic method using the microhardness investigated in some specific submicron structure subzones, such as the weld center zone, heat-affected zone (HAZ), base metal region, and the boundary between the weld metal and the HAZ.

This thesis deals with the finite element simulation of spot welded joint in crash analysis. Spot welding is a very common joining process in the automotive industry. It is cost effective and it provides a very fast production rate of automotive body components. Despite this advantage, spot welds are very susceptible to various types of loading conditions. Therefore they are prone to failure, if not designed properly, during their service life time. Therefore it is very important to understand the behaviour of spot welds and their failure characteristics.

In this paper, the butt welded joint of AISI 316L stainless steel plates is studied. The Metal Inert Gas (MIG) welding process is selected for this material. A SYSWELD software based on the Finite Element Method (FEM) is used to determine the temperature field and residual stresses of two stainless steel plates.
