Poland has solidified its position as Central Europe’s manufacturing powerhouse. From the heavy mining belts of Silesia to the maritime engineering hubs of Gdańsk, and the chemical corridors around Płock, Polish industries demand rugged components that can withstand extreme mechanical stress, intense abrasion, and corrosive environments.
Traditional welding processes often fall short when dealing with components that undergo heavy friction. This is where Plasma Transferred Arc (PTA) welding comes in. Offering an exceptionally low dilution rate, minimal heat-affected zones (HAZ), and a metallurgical bond that far outlasts mechanical coatings, PTA hardfacing has become the system of choice for maintenance, repair, and overhaul (MRO) professionals across Poland.
Our dedicated R&D facility focuses on pushing the limits of thermal surfacing. By integrating high-frequency arc stabilization, closed-loop powder feeding, and PLC automation, we manufacture equipment capable of continuous, heavy-duty cycles. Our machinery is developed to meet the strict demands of European safety standards (CE compliance) and to integrate seamlessly with standard factory automation lines (Siemens, Fanuc, and Kuka protocols).
Whether it is managing the dilution rate of expensive Stellite powders or optimizing the travel speed of a 6-axis manipulator positioner, our technical department provides comprehensive industrial equipment solutions that help maximize material yield and throughput.

As industrial automation scales up in the Polish market, procurement teams are comparing thermal surfacing options to optimize cost-per-part ratios. Understanding the technical divergence between PTA and High-Speed Laser Cladding is vital for selecting the appropriate production system.
One of the primary parameters for evaluating cladded layers is dilution rate—the amount of base material that melts and mixes into the protective alloy coating. While standard MIG/TIG welding results in a dilution of 15% to 30%, PTA technology restricts dilution to less than 5%, and Laser Cladding reaches less than 2%.
By utilizing our PTA machines, Polish factories can achieve structural hardness using a single layer of cobalt or nickel-based alloy, significantly saving on expensive powder consumables.
The roadmap for surfacing technologies involves integration with vision-based AI. We are developing smart tracking systems that adaptively change power output and powder feed rate on the fly, compensating for micro-geometric irregularities on used mechanical parts. This eliminates human error and guarantees consistent deposition quality.

| Dilution Rate | 3% - 8% | 1% - 3% |
| Deposition Rate | High (up to 6kg/h) | Medium (1-3kg/h) |
| Equipment Cost | Economical | High |

Common questions answered by our engineering and metallurgy application team.
Unlike thermal spraying, which relies on a mechanical bond and is susceptible to spalling, PTA welding creates a complete metallurgical fusion bond with the base metal. This ensures that the cladded layer cannot peel or flake off, even under intense impact or high cyclic pressure conditions commonly found in mining machinery.
