  • Critical Cooling Rate at 550 °C (1020 °F) (Tc). A critical cooling rate exists for each steel composition. If the actualcooling rate in the weld metal exceeds this critical value, then hard martensitic structures may develop in the HAZ, and there is a great risk of cracking under the influence of thermal stresses in the presence of hydrogen. The best way to determine the critical cooling rate is to make a series of bead-on-plate weld passes in which all parameters, except the arc travel speed, are held constant. ...

  • Although the grain microstructure of the TMAZ was significantly refined in comparison with that of BM, the FCG rate in TMAZ and base metal was shifted a comparable amount when the test temperature was elevated from room temperature to 200 oC. In the metallurgical view, the FCG rate in the fine grain TMAZ was higher than that in coarse grain HAZ and base metal site.

  • required generates very strong magnetic fi elds in the vicinity of electrolysis tanks and induction furnaces. Workshops manufacturing parts in PVC or rubber use high-frequency welding processes to perform assembly. The propagation of strong magnetic fi elds and high-frequency waves is not easily controllable. It creates local pollution in the midst of which the monitoring and control equipment must be able to operate.
