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 PRODUCTS.
In MANFISA WELDING PRODUCTS 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.
