Why thermal spray coating dominates other spray processes


Absolute customer focus is our priority. We are a provider of solutions to challenging welding applications. We ensure that our customers get the right materials, use them optimally and that the whole process parameters are followed for the best possible performance. We consider it as our responsibility to ensure that we deliver the value to our customers and offer the best feasible solutions. We also endeavor to develop new products, evaluate existing products and streamline processes to achieve the short turnaround times. We focus on technologically advanced industrial sectors and offer products that are geared to their special requirements.

We efforts to afford our customers the best feasible support and promote development in line with specific targets we have built our core competences in the joint welding, repair and maintenance, welding and soldering and brazing. We offer our customers the largest and most comprehensive products of filler materials.

Customers and distributed are supported by experienced welding engineers. In addition our aim is to be best in class motivates constant evolution through our complete dedication to research and development and ensures our customers are using the technically advanced welding products available today. Our product maintenance consists of innovative and tailored welding consumables from our own production facilities:

Flame Spraying
Flame spraying is a common thermal coating process. In powder flame spraying, the spray material, in powder form, is melted with an oxy-fuel gas flame, accelerated towards a component by the combustion gases and sprayed on the surface of the component.

The plastic powders can be processed by using spray guns particularly designed for those materials. Spray guns that commonly take the form of manual torches, specifically by using acetylene as a fuel gas because of its high flame temperature are selected for metallic alloys based on nickel, iron or cobalt. The powder particles that are partially melted by the flame, deform on impact with the surface of the component and are deposited there to develop a spray coating with a lamellar structure. The main application areas for thermal coatings are corrosion protection and wear protection.

Power flame spraying can be subdivided in cold and hot processes. In cold procedures, the powders are applied by the spray gun and spray coating is not subjected to any after thermal treatment.

Plasma Powder Surfacing
Plasma powder surfacing also called as plasma transferred arc process, is a thermal coating process. Unlike to the spraying process, this is a welding process and involves metallurgical bonding of the applied material to the base material.

Although if the parameters are suitably set, the extent to which it blends with the base material can be reduced to a minimum. It is used for surfacing of wear resistant and corrosion resistant coatings on to a base material. The process is featured by using two separately controllable electric arcs. One arc is pilot and the plasma nozzle. The grain sizes are chosen according to the system type.

Thermal spray wire coating

Besides of above coating processes, commonly used coating process is thermal spray wire coating that offers reliable coating. The scope of thermal spray wire is to repair the damaged components and increase component life.
