-With modern high-power lasers (and vacuum) penetration around 100 mm is possible
-Important for industrial applications: single-pass full penetration welds with tolerances
-Contactless EM-backing helps to overcome many main restrictions:
-Single-pass HLAW of up to 30 mm can be realized with 20 kW laser power
-Increase of the gap bridgeability and misalignement of edges
-Lower sensitivity to manufacturing tolerances and edge quality; samples can be prepared by a plasma-cut instead of time-consuming milling process
-Gives the possibility to increase the welding parameter window and cooling rate so that the required mechanical properties can be reached
-Improved filler wire mixing behaviour
