Welding Automation Across Core Industries

From valve seats to pressure vessels and mining bits — our automated welding & cladding systems serve 30+ countries and 2,000+ customers in valve, pressure-vessel, oil & gas, shipbuilding, auto-parts and mining manufacturing.

VALVE MANUFACTURING

Precision Cladding for Valve Seats, Wedges & Balls

Valve sealing surfaces demand high hardness and wear/corrosion resistance. Our PTA plasma transfer-arc and laser cladding systems overlay Stellite, Inconel and other alloys on seats, wedges, balls and discs with minimal dilution — serving control-valve and valve-component makers worldwide.

Products & Parts
Valve seats, stems, bodies, discs & flaps
Gate, globe, butterfly & ball valves
Large triple-offset butterfly valves
Bore / internal valve parts, socket welds
Special hard-seal valves
Clamping range φ10–φ600
Process & Equipment
01 PTA plasma cladding
02 Laser cladding
03 Hot-wire TIG cladding (CZ-TIG)
04 Robotic integration (ROBOT)
PRESSURE VESSEL

Automated Welding for Vessels, Tanks & Reactors

Pressure vessels, tanks and reactors require deep-penetration, defect-free longitudinal and circumferential welds. Our gantry SAW stations and saddle-welding systems handle shells, heads and nozzles for high/low-pressure vessels and heat-exchanger bodies.

Products & Parts
Vessel shells & bodies
Tanks, reactors & columns
Heat-exchanger shells & tube sheets
Manholes, nozzles & head saddles
Flanges & T-pipes
Swing diameter 6m / load 5T
Process & Equipment
01 Longitudinal + girth seam station (CZ-VESL)
02 Saddle SAW (CZ-MA)
03 Auto seam-tracking + AVC
04 SAW tractor / gantry
OIL & GAS

Overlay & Welding for Pipelines, Flanges & Wellhead

Pipelines, flanges and wellhead equipment need corrosion-resistant alloy overlay to withstand harsh sour-service environments. Our laser cladding and inner-wall (bore) welding systems overlay Inconel and other CRAs on pipes, flanges and downhole components.

Products & Parts
Pipe bore / inner wall
Drill collars, pipes & rotor journals
Wellhead & Christmas tree equipment
Flanges, RTJ grooves & reducers
Drilling wear parts
Ni- / Co-based composite parts
Process & Equipment
01 Internal pipe cladding machine (CZ-IN)
02 Ni 625 / Co Stellite cladding
03 Flange facing hardfacing (RTJ groove)
04 WC / CrC wear-resistant layer
SHIPBUILDING & OFFSHORE

Heavy-Duty Welding for Hull Plates & Offshore Structures

Shipyards need high-deposition welding for thick plates and complex structures. Our robotic MIG cells and gantry welding systems handle hull panels, pipe-shop spools and offshore sub-assemblies.
