2. Process to create joints between works having specific dimensions lower than 500 mm.
3. Process to create joints that are characterized by heat affected zones narrower than 200 mm.
4. Process to create joints by using filler metal which is positioned in high precision manner, the tolerances of the filler metal position being of hundreds of micrometers
