A method to join two metal parts without adding material is the use of a focused Laser beam. Sources with different wavelengths can be used (Nd:YAG or CO2) as well as different energy emissions (continuous or pulsed wave). The use of the Laser allows to minimize the HAZ (Heat Affected Zone) minimizing the thermal shock on the welded part, and to certify the welding process combining information referred to the welding position, energy supplied and energy absorbed.
The Laser technology assure an optional stability of the process thanks to a minimum maintenance, and to the absence of direct interaction between the welding device and the processed part.
MARSILLI has been working for a long time with Trumpf LASER to supply its customers the most suitable technological solution.
