PTA Welding Powders

Precision Coatings for Maximum Strength and Service Life

Plasma Transferred Arc (PTA) welding is a high-precision coatings method that produces dense, metallurgically bonded overlays with low dilution and superior wear resistance. Wall Colmonoy’s PTA welding powders are engineered for optimal performance in this advanced application, offering exceptional flow characteristics, stability, and consistency across high-temperature, high-impact environments.

PTA is ideal for surfacing components exposed to intense abrasion, corrosion, or thermal cycling – such as pump shafts, valve seats, plungers, cutting tools, neck rings, molds, guide plates, and more. This process allows for precise control of the weld pool and deposit thickness, delivering coatings that are both extremely durable and tailored to exact application needs.

Industries

Glass Container
Our advanced hardsurfacing alloys protect glass molds, plungers, and wear parts from extreme heat and abrasion, extending tool life and ensuring smooth bottle and jar production.
Oil & Gas
Drilling tools, pumps, and valve components in oil and gas operations benefit from our hardfacing alloys, which provide exceptional resistance to corrosion, pressure, and abrasive wear.
Pumps & Valves
From high-pressure chemical pumps to industrial flow valves, our advanced hardfacing alloys increase durability and prevent erosion in demanding fluid-handling applications.
Mining
Heavy-duty mining equipment - such as crushers, drill bits, and conveyor components - lasts longer with our wear-resistant alloys that combat impact, abrasion, and harsh conditions.
Rubber & Plastics
Our products protect extruder screws, molds, and processing dies in rubber and plastics manufacturing, minimizing friction-related wear and improving production efficiency.
Power Generation
Turbine blades, boiler components, and energy infrastructure benefit from our high-temperature resistant alloys, reducing oxidation, fatigue, and operational downtime.
Steel
From rolling mill guides to cutting tools, our hardfacing products help steel manufacturing equipment withstand extreme heat, pressure, and mechanical wear.
Automotive
Brake discs, engine components, and powertrain parts coated with our powders achieve superior wear resistance, improving performance and longevity in high-friction environments.
Agriculture
Our alloys extend the life of plowshares, harvester blades, and industrial mixers by protecting against abrasive soil, moisture, and heavy mechanical stress.
