another two kinds of MIG welding parameters are taken into account, see Table
2.3. Figure 2.6 shows the temperature history profile of the material point at 6 mm
away from the weld line with different welding parameters. The temperature and
displacement distributions along the C–C cross section for these three cases are
given in Figs. 2.7 and 2.8. These curves indicate that the maximum temperature
