The deposition welding (so-called armouring) and the joint welding is performed in-house manually as well as fully automated by using the corresponding robots.

Deposition welding or simply ”Armouring” means the application of metal layers on a basic body with the objective of selectively modifying the properties of the basic body at certain points in a way that these zones better withstand a certain load or stress than the basic body.
Therefore, a component is generated which combines the two properties in a way that the basic body for instance possesses the desired mechanic characteristics
and the applied layer withstands the expected stress such as wear, corrosion or heat.
The deposited layers can be applied in single- or multi-layers. I.e. the thickness of the layer can be adapted to the stress. By doing this, it would be possible to obtain a long durable protection.
Also, the choice of the alloy considerably influences the properties of the layer.
The deposition welding process can be selected according to the stress to be expected.
In our factory such layers are applied either manually by using a hand electrode or cored-wire or automatically resp. fully automated by using corresponding robots.
For the large-scale armouring of our A.S.S. bonded blanks (also called armour plates or bonded armour plates or compound plates) the
Tri-Pol process developed by us is being used.
This process guarantees a small amount of dilution with the base material and a very good surface.
Other processes that we use are deposition welding with core-wire (MIG-MAG) and the PPA (PTA) plasma powder deposition welding.
With all procedures applied by us, the welded on layer obtains its specific properties by numerous alloy variants, which we select depending on the stress.
It is often not necessary to armour the complete component or the complete surface. On the contrary, it would be reasonable and sufficient to protect only the surfaces which are subject to wear.
 

• A commercial protection is obtained by deposition welding.
• I.e. deposition welding ensures the reduction or avoidance of signs of wear by abrasion, impact, erosion, cavitation or impact of heat.
• Deposition welding often makes other measures (treatments) such as e.g. hardening superfluous.
• By deposition welding the service life (of a component) can be considerably extended. Depending on the kind of wear, the extension may amount to a multiple of the standard, i.e. unprotected component.
• Maintenance intervals on machines and plants are extended and downtimes are reduced.
• This means: The economic efficiency of a component or of the machine is considerably increased.
• Deposition welding can be performed on new parts as well as on used parts.
• If a component was already designed for deposition welding, it may generally be produced from an economically priced material.
• Normally, it is possible to re-armour it after use.
• The repair of a worn out component by deposition welding often costs significantly less than a new component.
