High Pressure Welding Services

Certified high-pressure welding to code — X-ray quality TIG, MIG, and stick welding for critical industrial
applications across South Africa. Fully compliant with South African Pressure Equipment Regulations.

Welding You Can Trust Under Pressure

Our welding services support our broader capabilities in pipework, pressure vessel manufacture, and structural fabrication — delivering certified weld quality that gives clients and inspectors complete confidence.

When it comes to high-pressure applications, the quality of every weld is critical. A failed weld in a pressure vessel or steam line is not just a maintenance issue — it's a safety and liability risk. Smitson Engineering CC employs certified welders who work to strict codes and produce welds that can withstand the most demanding industrial conditions.

Welding Certifications & Standards

Certified to Code

Our welders are qualified per South African and international welding codes. X-ray (radiographic) testing available to confirm weld integrity on critical joints.

Our Welding Process Capabilities

TIG Welding (GTAW)

Gas Tungsten Arc Welding — the gold standard for high-quality, precision welds on stainless steel and other alloys. Ideal for food-grade, pharmaceutical, and high-purity applications where weld aesthetics and cleanliness matter.

MIG Welding (GMAW)

Gas Metal Arc Welding — efficient and versatile, used for structural fabrication, mild steel, and many stainless steel applications. High deposition rates for productive fabrication while maintaining quality standards.

Stick Welding (SMAW)

Shielded Metal Arc Welding — robust and versatile, suitable for site work, structural joints, and repair welding. Certified for high-pressure applications to the required welding procedures.

X-Ray (Radiographic) Testing

Radiographic testing of critical welds provides documentary proof of internal weld integrity — revealing porosity, inclusions, lack of fusion, and cracks that visual inspection cannot detect. Essential for pressure vessel and high-pressure pipework.

Pressure Vessel Welding

Specialised welding for pressure vessels — working to design code requirements, with full documentation, inspection, and certification. We have manufactured 89+ pressure vessels for export and domestic use.

On-Site Welding

Our certified welders travel to site for project work — from pipeline installation to structural repairs. Fully equipped for shop and field welding across South Africa.

Our Welding Process Capabilities

316 Stainless Steel

Highest corrosion resistance — for chemical, solvent, marine, and food applications.

304 Stainless Steel

Food-grade stainless for dairy, food processing, and hygienic applications.

Mild Steel

Structural, steam, and general industrial — the workhorse material of industrial fabrication.

Carbon Steel

High-pressure steam lines, pressure vessels, and high-temperature applications.
