Hall A3, Booth 411

Sisma will be showcasing its Power Ramp software function, developed to optimise laser welding processes, specifically at two critical points – the start and end of the welding process.

Power Ramp operates at the start of the welding process by reducing the power supplied by the laser beam and gradually increasing it until the selected nominal value is reached. In the final phase of the welding process, Power Ramp operates inversely, reducing the nominal power delivered by the laser beam to obtain a gradual shutdown. 

By modulating the power delivered by the laser beam in the initial and final phases of a welding process, Power Ramp is able to avoid the onset of porosity and cracks, marginal incisions – surface depressions that can be generated at the end of the weld bead – as well as prevent the formation of any other aesthetic and functional defects. 

In addition to Power Ramp, Sisma will also be showcasing its MYSINT 100 metal 3D printer, and multiple vision systems for process monitoring at its booth.
