ABS Approved 6G Pipe Welding Service in Vietnam Ports

In the marine and offshore industry, class-compliant welding is not optional — it is mandatory. For critical piping systems onboard vessels, compliance with international classification society standards ensures structural integrity, safety, and seaworthiness.

At Hai Phong Ship Repair – Bacviet Commercial & Shiptech JSC, we proudly provide ABS Approved 6G Pipe Welding Service in Vietnam Ports, supported by certified Welding Procedure Specifications (WPS) and qualified welders under ASME Section IX.

Our 6G carbon steel pipe welding procedures are officially approved by American Bureau of Shipping (ABS), ensuring compliance with strict international marine repair regulations.

What Is ABS Approved 6G Pipe Welding?

The 6G welding position is one of the most difficult pipe welding qualifications. It requires welding a pipe fixed at a 45-degree angle, testing the welder’s ability to control weld penetration, root pass integrity, and fusion across all positions.

When a WPS is ABS approved, it means:

Welding parameters are validated and tested
Mechanical properties meet class requirements
Impact and tensile strength comply with marine standards
Procedure qualification records (PQR) are verified
Welder performance qualifications (WPQ) are witnessed and certified

For shipowners and technical superintendents, this ensures that any piping repair affecting class systems will be accepted during survey.

Why 6G Qualification Matters in Marine Pipe Repair

Marine pipe systems operate under:

High pressure
High temperature
Vibration loads
Corrosive seawater environments

Improper welding can result in:

Leakage
Structural failure
Loss of class
Vessel detention
