- Result: EN ISO 3834-2:2021 certification issued by Bureau Veritas Vietnam.

ISO 3834 consulting for engineering and steel structure businesses
For engineering and steel structure manufacturers, weld quality directly affects product strength, safety and conformity with technical requirements. Controls need to start during preparation and continue through production, inspection and acceptance.
Businesses seeking to establish welding quality controls can explore ITVC’s ISO 3834 consulting service. The Bac Viet project illustrates how standard requirements can be translated into specific factory activities.
At Bac Viet, ITVC supported the assessment of existing arrangements, procedure development, implementation guidance and review of areas requiring improvement against ISO 3834. Following implementation, the business was assessed and certified by an independent certification body.

The value of consulting lies in helping the business establish a structured welding quality management system: understanding what needs to be done, what must be controlled, how to carry out activities, who is responsible and which records demonstrate implementation. The resulting system must also meet international standard requirements. This provides a basis for maintaining the system and improving quality in daily production.

Benefits of ISO 3834 consulting for welding quality control
ISO 3834 consulting translates standard requirements into work suited to actual factory conditions, supporting four practical benefits.
1. Reducing defects and repair costs
Review activities where defects may arise and define controls before, during and after welding. Timely identification and correction of deviations provide a basis for reducing rework, material waste and schedule delays.
2. Clear responsibilities and practical implementation
Allocate responsibilities across engineering, production, quality inspection and welding coordination, and review the competence of personnel involved in welding. Consistent procedures and instructions make cooperation between departments easier.
3. Complete and retrievable records
Organise documents and quality-control evidence so they can be readily checked during acceptance, technical problem-solving and discussions with customers or certification bodies.
4. Strengthening the ability to meet customer requirements
An effectively implemented system, together with appropriate certification, provides evidence of welding process control capability and supports contractual, tender and partner requirements.
Personnel involved in the project also develop specialist welding knowledge, helping them operate the system independently after consulting support ends.
The ISO 3834 consulting process at Bac Viet: five implementation steps
- Assess the current situation: review production, welding processes and existing quality controls to identify what needs to be added.
- Develop and improve the system: guide the preparation of procedures, documents and forms suited to ISO 3834 requirements and the company’s conditions.
- Guide practical implementation: integrate controls into everyday work, linking documentation with production activities and departmental responsibilities.
- Review conformity: check implementation, identify gaps and advise on corrective measures before certification assessment.
- Prepare for certification assessment: support the review of records, documents and arrangements needed to work with the independent certification body.
ITVC provides consulting and implementation support. Assessment and certification decisions belong to the independent certification body.

What activities does ISO 3834-2:2021 cover?
ISO 3834 is a series of standards covering quality requirements for fusion welding of metallic materials. ISO 3834-2:2021 sets out comprehensive quality requirements applicable to welding in workshops and at field installation sites.
For engineering, equipment manufacturing and steel structure businesses, selection of the relevant part and scope should reflect products, welding processes, technical requirements and customer expectations. Early consulting helps define the appropriate scope and focus resources where they are needed.
Frequently asked questions about ISO 3834 consulting
What should a business prepare before implementation?
Gather information about products, materials, welding methods, production locations, responsible personnel and customer requirements. Existing welding procedures, personnel competence records, inspection results and management forms help ITVC assess the current situation and discuss the consulting scope.
What affects consulting cost and duration?
These depend on product scope, the number of sites, the readiness of personnel and records, required improvements and the intended schedule. ITVC discusses each business’s needs and current arrangements before proposing the scope, implementation plan and quotation.
