WebWhen we've got two welds close to each other, the width of the heat affected zone is the width of the group weld because it may overlap. Sometimes in order to achieve the thickness of the weld we may need to lay down multipass welds. In this case we expect that the temperature will be increased. WebHAZ is created during the laser cutting due to more localized heat and is the closed cutting zone (see Figure 7 ). Width size of HAZ is enhanced with the increase in energy input and cutting...
