Web8 de jun. de 2016 · A prediction of the size of the heat affected zone (HAZ) should be made before cutting to select the proper cutting parameters and to reduce the size of the HAZ. A series of cutting experiments were carried out in this study by using an oxy-ethylene flame to obtain the widths of the HAZ for the I and V grooves of steel plates, and the effects due …
WebThe depth of deposition of the heat-affected zone is determined by the initial and final temperatures of austenitization A 1 = 723 °C and A 3 = 835 °C, while a fusion line by the solidus temperature 1493 °C is presented in Figure 16. The depth is increasing with subsequent welds—after five beads, an increase of 0.5 mm is observed.
