In 2016, MANFISA began producing drawn wire for welding purposes. Due to the specific characteristics of this product, both technical and in terms of complying with different specifications and implementing regulations, a new Division was created: MANFISA WELDING.

In MANFISA WELDING we produce weld metal exclusively made from aluminium. In order to ensure maximum quality and to attend the specific needs of the welding market, a new production plant has been launched in 2019 with the sole purpose of producing aluminium weld metal.

We have new facilities and modern production equipment, as well as a new laboratory where we can monitor production and develop new I+D projects.
