Measurements of contraction process during first-pass welding and cooling were undertaken and the results compared with the analytical results in Part 1. Mild steel specimens of 5 through 150 mm thick as shown in Fig. 1 were used. Contraction during welding and cooling was recorded by oscillograph over five gauge lengths AA´, BB´, CC´, DD´ and EE´ in Fig. 2. Thermal cycles were also recorded at a few points in weld metal and mother plate. Figs. 4 through 6 show typical examples of the test results. Their characteristics almost agree with those predicted by analytical approach shown in Fig. 7. Some analyses showed good agreement between test results and calculations. (See Figs. 8 through 11.) However a little difference between them was attributed to the effect of moving of welding heat source which was neglected in the analysis.
