TL;DR: In this paper, the authors present a review of the development of welding simulation and the directions for future research, which is summarized in this review, which consists of three parts: the important development of material modeling and computational efficiency are outlined in Parts 2 and 3, respectively.
Abstract: Simulation of welding has advanced from the analysis of laboratory setups to real engineering applications during the last three decades. This development is outlined and the directions for future research are summarized in this review, which consists of three parts. This part shows that the increased complexity of the models gives a better description of the engineering applications. The important development of material modeling and computational efficiency are outlined in Parts 2 and 3, respectively.

TL;DR: In this article, a review of the development of simulation of welding has been presented and the directions for future research are summarized in this review, which consists of three parts: material modeling, material behavior, and future research directions.
Abstract: Simulation of welding has advanced from the analysis of laboratory setups to real engineering applications during the last three decades. This development is outlined and the directions for future research are summarized in this review, which consists of three parts. The material modeling is maybe the most crucial and difficult aspect of modeling welding processes. The material behavior may be very complex for the large temperature range considered.

TL;DR: In this paper, the main emphasis is on thermal modelling and prediction of laser welding in metals, and a review is given over to the modelling of these processes where appropriate, where the time frame of the review is up to the year 2002.
Abstract: The main emphasis of this review is on thermal modelling and prediction of laser welding in metals. However as similar techniques are employed to model conventional welding processes such as arc, resistance and friction, as well as related processes such as alloying, cladding and surface hardening, part of this review is given over to the modelling of these processes where appropriate. The time frame of the review is up to the year 2002.
246 citations
TL;DR: In this article, both the experiment and the finite element method (FEM) are utilized to investigate the welding residual stress distribution in medium thick-walled austenitic stainless steel pipe.
