Waste-based consumable for hardfacing by welding: a look from the Circular Economy

Dyna
In the present work, the obtaining of a consumable for the restore parts by welding from the perspective of the circular economy is addressed, using industrial solid residuals (slag from steel production, graphite from fragments of electrodes of arc ...
