Capabilities
Beyond precision CNC machining, Periyasamy Industriess brings welding and special processes in-house — joining nickel superalloys, titanium and exotic steels, then completing them through heat treatment, non-destructive testing and protective coatings to deliver flight-critical aerospace assemblies ready for service.

Our welders qualify to demanding aerospace and structural standards, producing sound, defect-free joints across nickel superalloys, titanium and a full range of steels and aluminium — every weld backed by traceable procedures and inspection.
High-temperature, high-integrity welding of Inconel and other nickel-based superalloys for hot-section hardware such as combustion liners, exhaust frames and turbine components. Controlled heat input and matched filler metallurgy preserve creep and oxidation resistance where service temperatures are extreme.
Inert-gas and controlled-atmosphere welding of aerospace-grade titanium including Ti-6Al-4V. Full argon shielding and trailing-gas coverage keep the weld and heat-affected zone free from oxygen and nitrogen pickup, producing bright, ductile joints for lightweight structural and propulsion assemblies.
Corrosion-resistant welding of austenitic and martensitic stainless steels for pressure chambers, fluid systems and precision fabrications. Low-distortion techniques and clean, passivation-ready welds maintain leak-tight performance and long service life in aggressive environments.
Welding of duplex and super-duplex stainless steels that demand a balanced austenite-ferrite microstructure. Careful control of heat input and interpass temperature delivers the high strength and pitting resistance these alloys are specified for in demanding structural and corrosive-service applications.
Welding of aerospace aluminium structures, rings and fabrications using AC inert-gas processes with rigorous pre-weld cleaning to eliminate oxide and hydrogen porosity. The result is sound, lightweight joints for structural frames and rolled-ring assemblies where weight and integrity both matter.
Structural welding of carbon and low-alloy steels for fixtures, jigs, tooling and heavy assemblies. Robust, high-deposition procedures build strong, dependable joints on load-bearing weldments and the ground support equipment that underpins our machining and assembly operations.
Special Processes
From structural assembly through metallurgical treatment, testing and protective finishing, our special processes take a machined component all the way to a certified, service-ready deliverable — with full traceability at every step.
Welding of thrust-frame and structural assemblies, joining machined details into rigid, load-bearing weldments that meet aerospace dimensional and integrity requirements.
Controlled thermal cycles develop the target hardness and stress state, managed through a defined hardening, sub-zero and tempering sequence.
Non-destructive and mechanical verification — Radiography (RT) and Dye-Penetrant (DP) inspection to reveal internal and surface flaws, with Tensile testing to confirm joint strength.
Chemical passivation restores and enhances the corrosion-resistant oxide layer on stainless components, removing free iron and leaving a clean, durable, corrosion-resistant surface.
Hard-Teflon (PTFE) coating applies a low-friction, wear- and chemical-resistant surface, protecting critical components and improving release and durability in demanding operating conditions.
An AS9100D-aligned, zero-defect culture governs every operation, with material traceability and documented records that follow each component from raw stock to final delivery.
