Among the multiple applications of laser technology, cladding is emerging due to its high metallurgical quality, the limited heat input to the piece and the mixing contained to a minimum with the base material.
The deposits are perfectly anchored and the melting of the base metal is so limited that the analysis and characteristics of the filler metal are practically unchanged even in the area adjacent to the interface.
Under these conditions, the deformation of the pieces is almost zero. Often the piece can be welded without pre-heating even in the presence of hard or brittle filler alloys.
The high cooling rate of the weld beads also determines a fine grain structure of the deposit.
