The Theory of Moving Sources of Heat and Its Application to Metal Treatments
Abstract
The theory of moving sources of heat has been instrumental in providing the welding engineer with a scientific criterion of weldability of steels. The author outlines briefly the fundamentals of this theory and derives appropriate solutions for linear, two- and three-dimensional flow of heat in solids of infinite size or bounded by planes. Point, linear, and plane sources of heat are examined. The solutions obtained are then applied to welding problems. It is shown that these solutions are in good agreement with the experimental results, and that they afford a close analysis of the factors governing the heat flow in welding. The most interesting result of the theory, however, is the derivation of a single formula capable of predicting the time and rate of cooling with a fairly good accuracy for a wide variety of thicknesses of steel, ranges of temperature, and welding conditions. An attempt has been made also to show how this theory could be applied to other problems of metal treatment, such as rate of extrusion in continuous casting, or control of flame-hardening and continuous quenching operations.

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
