Green boundary welding
WebJun 29, 2009 · The effect of manganese addition on decreasing hot crack susceptibility of submerged arc welding in microalloyed steels is well understood, but its increment should not cause unsuitable changes in metallurgical and mechanical properties of weld metal. Therefore, since weld metal Mn content in SAW process is mainly controlled by welding … WebJan 1, 2015 · The images of the monitored welding process are recorded in ‘AVI’ format and then the each frame is processed to extract the weld pool boundary, followed by the calculation of the welding width. The experimental welding speed ranges from 1 m/min to 5 m/min. Fig. 5 shows the original unprocessed images with varied welding speeds.
