Abstract:

This thesis deals with the numerical simulation of welding processes. The analysis is focused either at global level, considering the full component to be jointed, or locally, studying more in detail the heat affected zone (HAZ). Even if most of the considerations are quite general, two specific welding technologies are studied in depth: multi-pass arc welding and its extension to Shaped Metal Deposition (SMD) processes (global level analysis) and Friction Stir Welding (FSW) technology (local framework). The analysis at global (structural component) level is performed defining the problem in

Abstract:

The butt fusion process is extensively used in the joining of polyethylene (PE) pipes by the water and gas industries. This welding process although deceptively simple, is rather poorly understood, with much of the initial developments being of a rather empirical nature. The Water Research centre (WRc) have funded the present research in an attempt to optimise the welding of high pressure pipeline (PE100) systems. The main aims of this research were to investigate the effect of different welding conditions on the physical and mechanical properties of the joints produced and to investigate thes

Abstract:

This thesis is focussed on shielding gas optimisation in gas shielded arc welding processes, and has been conducted along two themes; deriving conditions in which the shielding gas flow rate can be safely reduced, and through the highly novel process of alternating shielding gases. The correct shielding gas flow rate is essential for providing adequate protection to the weld metal during the heating, liquid and solidification stages. Hence, there is an optimum shielding gas flow rate, but this is difficult to define and is often decided on the basis of preference or experience. A multi-discipl

Abstract:

The ability to make rational decisions based on the synthesis of various pieces of information and to eventually arrive at an integrated design plays a very important role in everyday engineering practice. In this paper, a conceptual framework for manufacturing design is obtained through a causal perspective. This framework is used in developing a knowledge-based system that gains insight into the process of arc welding from a few detailed analyses and experiments on simplified models and rationally arrives at an integrated design of the actual process using a hybrid axiomatic-algorithmic appr

Abstract:

Out-of-plane welding distortion has been a persistent problem in welding industries. In order to find solutions for such a problem, substantial experimental and computer modelling work on residual stresses and out-of-plane distortion analysis need to be carried out. Such computer modelling requires the temperature fields or histories during welding as pre-requisite input which can be obtained either from actual measurement or computer simulation. The object of this thesis is to develop computational techniques which can be used to compute these temperatures. Experimental work on temperature me

In this thesis a variety of problems are considered, the first of which is associated with the welding process. Experiments indicate that the shape of a weld pool is influenced by convection in the liquid metal. In recent years it has been shown that this convection is crucially affected by the Marangoni (or thermocapillary) force. Recently Craine and Belgrove ([30], [7]) have developed a two-dimensional, axisymmetric model which includes the Marangoni force on the free surface of a semi-infinite region of liquid steel when a point source of current and heat is incident on the free surface.

Abstract:

The aim of this research was to develop an adaptive quality control strategy for robotic gas metal arc welding of thin steel sheets. Statistical methods were used to monitor and control the quality of welds produced. The quality of welds cannot be directly measured during welding. It can however be estimated by correlating weld quality parameters to relevant process variables. It was found sufficient to do this using welding current and voltage transient signals only. The strategy developed was problem solving oriented with emphasis on quality assurance, defect detection and prevention. It was

Abstract:

The transient temperature fields induced by welding processes largely determine the size of the fusion and heat-affected zones, the microstructures, residual stresses and distortion both in the vicinity of the weld and in the final component as a whole. An accurate prediction of these fields relies heavily on the representation of the welding heat source, both in space and in time. The double-ellipsoidal heat source model proposed by Goldak and co-workers has been widely used to simulate the heat transferred from an electric arc to a component and to compute the induced transient temperature f
