 Products Catalog: Electroslag Strip Cladding
Electroslag Strip Cladding Process
Source of heat : joule effect in molten slag
Dilution : 7 - 10 %
Deposition rate : 22 kg/ h or 0.6 m2/ h

The electroslag strip cladding process strongly resembles its submerged arc counterpart. The strip is feeded to the weld pool without an arc. Again, the flux forms a protective slag. Unlike the slag of the submerged arc process, this....

 Products Catalog: Submerged Arc Welding
Submerged Arc Strip Cladding Process
Source of heat : electrical arc
Dilution : 12 – 18 %
Deposition rate : 14 kg/ h or 0.4 m2/ h

The energy to melt the strip and the base metal is supplied by the electric arc struck between them. On melting, the agglomerated flux protects the liquid metal and where applicable enriches it with alloying elements. Submerged arc cladding is....

 Products Catalog: Powder Spray Coating
This process is basically the spraying of molten material onto a surface to provide a coating. Material in powder form is melted in a flame ( oxy-acetylene or hydrogen most common) to form a fine spray. When the spray contacts the prepared surface of a substrate material, the fine molten droplets rapidly solidify forming a coating.
Flame spray, also known as oxy/ acetylene combustion....

 Products Catalog: Cold Process Metal Coating
In the Arc Spray Process, a pair of electrically conductive wires is melted by means of an electric arc. The molten material is atomized by compressed air and propelled towards the substrate surface. The impacting molten particles on the substrate rapidly solidify to form a coating. This arc spray process carried out correctly is called a & quot; cold process& quot; ( relative to the....
