40313 2017 eng poster 0 -- -- -- Time- and space-resolved in situ LIBS measurements of chemical compositions during TIG-welding An in situ monitoring of chemical compositions in the weld pool and the heat affected zone (HAZ) can enable the control of the welding process through the regulation of the welding parameters, and thus can prevent possible weld defects. The most critical parameter for hot cracking -from a metallurgical point of view- is the chemical composition of the weld pool. Chemical composition can be measured and quantified during the welding process with the LIBS technique having the appropriate calibration measurements.
