EN ISO 3834-2 – The perfect piece for World Steel’s quality management system

ISO 3834-2 is an international standard for quality management systems in welds for companies operating in the welding field. It is part of the ISO 3834 series of standards, developed by the International Organization for Standardization (ISO) and applicable to welding in various industries.

The ISO 3834 series of standards – Quality requirements for fusion welding of metallic materials, issued in 2005, includes the following Standards:

  • ISO 3834-1: Criteria for the selection of the appropriate level of quality requirements
  • ISO 3834-2: Comprehensive quality requirements
  • ISO 3834-3: Standard quality requirements
  • ISO 3834-4: Elementary quality requirements
  • ISO 3834-5: Necessary documents to be followed to conform to the above quality requirements

ISO 3834-2 certificate is the highest level of certificate when evaluating the welding quality management system of a manufacturing company. This is the comprehensive level. And at this level, our welding quality management system is recognized as suitable for manufacturing steel structures and products with welded joints from the simplest to the most complex according to ISO standards. Here is the notable range of weld seam quality that EN ISO 3834-2 certificate recognizes:

When receiving the ISO 3834-2 certificate from a reputable organization like BV Viet Nam, it also means that World Steel's steel structure factory is facing opportunities and challenges:


That is, we are independently validated for our perfection in welding operations and manufacturing capacity in the field of specific mechanical manufacturing. Enhance domestic and international competitiveness by demonstrating compliance with welding quality requirements with internationally recognized standards. Meet the requirements of investors when participating in bidding because ISO 3834 is often used as a mandatory requirement in processing and manufacturing contracts by welding methods in the EU and many industrialized countries.


Because we must always improve and strive continuously to meet and maintain the strict requirements of ISO 3834 standards as well as our commitment to providing customers with the best products and services. And we believe we can do it to the best of our ability.

Achieving ISO 3834-2 certificate proves that World Steel complies with the processes, methods and technical requirements to ensure the quality of welded structures, producing products that meet high-quality standards. This ensures that World Steel is capable of providing high-quality, reliable and safe welding products to clients.

It proves that the company has employees with enough knowledge and skills to perform high-quality welding jobs. Choosing World Steel can bring peace of mind and confidence in working with a highly capable and reliable supplier in the welding field.
