Constant monitoring of the entire supply chain for a guarantee of excellence without compromise
All 3 plants are certified according to the ISO 9001.
Isaf S.p.A. is certified by DNV while Isaf Gmbh is certified by TÜV.
All production plants operate in compliance with the EU regulation 305/2011.
We manufacture welding wire starting from raw material source from the main steel mills in Italy and in Germany. All these steel mills are certified and approved by the main international organizations. The wire rod is selected according the norms UNI EU 133 and we use internal purchasing specifications.
Strict control of incoming raw materials is guarantee of efficient processing and excellent mechanical properties.
The production process is completely and constantly monitored by the Quality Control.
The drawing is done with more technologically advanced machines; continuous coppering, perfect concentricity and optimum spooling are therefore always guaranteed.
For each diameter we have defined the following parameters:
|Wire diameter||Min. cast diameter||Max. cast diameter||Max. helix|
|0,80 / .030||700 / 28||1200 / 47||8,0 / 3|
|1,00 / .035 (0,9)||800 / 31||1200 / 47||8,0 / 3|
|1,20 / .045||900 / 35||1200 / 47||10,0 / 3|
|1,60 / 1/16||1000 / 39||1200 / 47||10,0 / 3|
Little helix ensures a good feeding of the wire in the liner of the torch with 6-8 meters length too. The control of the diameter size is guaranteed (tolerances - 0.03mm/ + 0.01mm) by a laser system; this system stops the machine in case the tolerance is not respected.
The coppering system of our wire guarantees that copper put on the wire is according the parameters as follows:
|Diam. - mm / in.||% Cu surfacing
|1,20 / .045
|1,00 / .035 (0,9)
|0,80 / .030
