PPV CORP Welding & Fabrication Process
At PPV CORP, we follow a rigorous pipe welding and pipe fabrication processes to ensure all projects meet ASME, API, AWS, and other industry standards. Our process is designed to deliver high-quality, consistent results for pressure vessels, piping, process systems, and structural components.
Step 1 – Design & Engineering
Every project begins with detailed engineering and design. Our team reviews specifications, materials, and codes to develop a comprehensive Welding Procedure Specification (WPS). This ensures welders have clear guidance for producing welds that meet mechanical and code requirements.
Step 2 – Material Preparation
We carefully select and prepare base metals and filler materials for piping fabrication and piping spool welding—including carbon steel, stainless steel, duplex, super duplex, aluminium, and cryogenic materials. Pre-weld treatments such as cleaning, bevelling, and pre-heating are performed as required by the WPS.
Step 3 – Welding Execution
Certified ASME Section IX welders carry out the welding using approved techniques, amperage ranges, and shielding gas compositions as specified in the WPS. Our in-house Certified Welding Inspectors (CWI) monitor each weld to ensure quality, consistency, and compliance.
Step 4 – Inspection & Testing
All pipe spool welds undergo rigorous inspection and testing, including visual inspections, non-destructive testing (NDT), and code-specific verification. This step ensures each piping weld meets or exceeds mechanical property requirements and client expectations.
Step 5 – Assembly & Delivery
After pipe welding and piping spool inspection, pipe spool components are assembled into modular skids, pressure vessels, piping systems, or structural frameworks. Final QA checks ensure everything is delivered on-time, fully compliant, and ready for installation or service.

- TIG Welding - Gas Tungsten Arc Welding (GTAW)
- Flux Welding - Cored Arc Welding (FCAW)
- Submerged Arc Welding - Sub-Arc Welding (SAW)
MIG WELDING (GMAW)
MIG welding is one of the easier types of welding for beginners to learn. MIG welding is actually two different types of welding. The first uses bare wire and the second flux core.
Bare wire MIG welding can be used to join thin pieces of metal together. Flux core MIG welding can be used outdoors because it does not require a flow meter or gas supply. MIG welding is usually the welding of choice for DIY enthusiasts and hobby welders who don’t have the money to spend on expensive equipment.
