Q&A/ Welding Test
Question 04

What standards govern welding tests in India?

Welding tests in India are governed by a combination of Indian Standards (IS) as well as internationally accepted codes, depending on the industry, project requirements, and client specifications.

Some of the key standards and codes include:

  • Indian Standards (IS codes) issued by the Bureau of Indian Standards (BIS), which provide guidelines for welding procedures, inspection, and quality requirements in various applications
  • ASME (American Society of Mechanical Engineers) Boiler and Pressure Vessel Code, widely used in power plants, oil & gas, and pressure vessel fabrication
  • AWS (American Welding Society) standards, commonly followed for welding procedures, qualification, and inspection practices
  • ISO standards (International Organization for Standardization), which define global best practices for welding quality and testing
  • Client and project-specific specifications, often used in large infrastructure, EPC, and industrial projects in India

These standards define requirements for Welding Procedure Specification (WPS), Procedure Qualification Record (PQR), welder qualifications, inspection methods, and acceptance criteria.

At Uniquo, we conduct welding tests in strict compliance with applicable Indian and international standards to ensure safety, reliability, and regulatory compliance across all industries.
