Abstract

The transient temperatures that develop in a welded mild steel plate dur- ing welding are measured and compared with the predictions of a computer program that has recently been developed [1]. It is found that the calcula- tions can be performed using a surprisingly coarse mesh. The shape of the temperature-time curve, particularly the slope of the curve immediately after the peak temperature has been reached, depends on the value of the conductivity used in the calculation. The predicted surface temperatures are in good agreement with measurements; however, some unexpected re- sults were obtained at the plate mid-thickness. It turns out that even a small deviation of the weld line markedly affects the temperatures at points near it. 1 Introduction
