Heat transfer and fluid flow during manual metal arc welding of low alloy steels were investigated by solving the equations of conservation of mass, momentum, and energy in three dimensions. Cooling rates were calculated at various locations in the weldment. Calculated cooling rates were coupled with an existing phase transformation model to predict percentages of acicular, allotriomorphic, and Widmanstaetten ferrites in various low alloy steel welds containing different concentration of V and Mn. Computed microstructures were in good agreement with experiment, indicating promise for predicting weld metal microstructure from the fundamentals of transport phenomena.

This book reviews the behaviour of metals and alloys during welding. In the first part the heat flow in arc welding processes is discussed. The weld thermal cycle is explained in terms of heat input, and the geometry of weld and thicknesses to be welded. The real welding cycle is described in terms of thermal and strain cycles. The weld metal is characterized in terms of fusion stage, absorption of gases and stage of metal crystallization and structural transformation. The metallurgical background of cracking is described by a full set of crackability tests along with the evaluation of metals from the point of view of crackability. Post welding heat treatment is reviewed, and includes the relaxation of stresses induced by welding. Guidelines are given for the selection of steels for welded structures. Several chapters examine the weldability of particular steels, including high strength steels, stainless steels, high alloyed steels, cryogenic steels and other metals and alloys. The theories are quantified in the form of calculations or computing programmes. Readers will find sufficent data for software processing.

The book describes the results of over 20 years research completed this year at one of the world's premier consumable manufacturers and aimed at improving the properties of MMA electrodes for high quality applications. It examines the influence of some 17 elements and welding variables on the composition, microstructure and mechanical properties of the resulting weld metal. The often complex relationships discovered are sufficient to give a good understanding of the properties of weld metals produced by other arc welding processes.

Heat transfer and fluid flow during manual metal arc welding Of low alloy steels were investigated by solving the equations of conservation of mass, momentum and energy in three dimensions. Calculated cooling rates were coupled with an existing phase transformation model to predict the microstructure in low alloy steel welds. The computed results were found to be in good agreement with experimentally observed microstructures. The agreement indicates significant promise for predicting spatial distribution of weld metal microstructure from the fundamentals of transport phenomena.
