Use of ISO 3834-2:2005

• ISO 3834-1 provides general information on the use of this standard.
• To fulfill the quality requirements outlined in this document, compliance with relevant documents listed in ISO 3834-5 must be confirmed.
• Specific sections of the requirements may be selectively amended or deleted in certain situations.

Non-Destructive Testing Personnel

• Non-destructive testing personnel must be qualified and certified.
• Qualification tests are not required for visual testing, but competence must be verified by the manufacturer.
• The ISO documents required for conforming to quality requirements for arc welding, electron beam welding, laser beam welding, gas welding and other fusion welding processes are specified in tables 3 and 10 of ISO 3834-5:2005.

Equipment Requirements

• Production and testing equipment: includes power sources, machines, joint and surface preparation equipment, cutting equipment, preheating and post-heat treatment equipment, jigs and fixtures, cranes, handling equipment, personal protective equipment, welding consumables treatment facilities, surface cleaning facilities, destructive and non-destructive testing facilities.
• Description of equipment: the manufacturer must maintain a list of essential equipment used for production, including information on capacity of cranes, size of components the workshop can handle, capabilities of mechanised or automatic welding equipment, dimensions and maximum temperature of furnaces for post-weld heat treatment, and capacities of rolling, bending and cutting equipment.
• Suitability of equipment: equipment must be adequate for the application in question.
• New equipment: appropriate tests must be performed on new or refurbished equipment to verify its correct function, documented in accordance with relevant standards.
• Equipment maintenance: manufacturers need documented maintenance plans to ensure inspections of items necessary for controlling variables listed in relevant procedure specifications. These plans may be limited to essential items for assuring product quality, such as guides in thermal cutting equipment, ammeters, voltmeters, flow meters, cables, hoses, connectors, control system in mechanised or automatic welding units, temperature-measurement instruments, wire feeders and conduits. Defective equipment must not be used.

Welding and Related Activities

• Production planning: the manufacturer must conduct thorough production planning, considering factors like the sequence of construction manufacturing, work instructions, welding-procedure specifications, and testing methods.
• Welding-procedure specifications (WPS): these documents should be prepared and approved by a qualified person, with detailed procedures for making welds.
• Welding-procedure qualification records (WPQR): these records document the qualification of the WPS through testing.
• Work instructions: These instructions are derived from qualified WPSs and do not require separate qualification.
• Procedures for document preparation and control: manufacturers must establish procedures for preparing and controlling documents such as WPS, WPQR, welder and welding-operator qualification certificates.

Welding Consumables

• General: manufacturers must define responsibilities and procedures for controlling welding consumables.
• Batch testing: batch testing of welding consumables is only required if specified.
• Storage and handling: manufacturers must create procedures for storage, handling, identification, and use of welding consumables in line with supplier recommendations.

Storage of Parent Materials

• Parent materials should be stored in a way that prevents deterioration, and they must be identified during storage.

Post-Weld Heat Treatment

• Manufacturers are responsible for specifying and implementing post-weld heat treatment, ensuring compatibility with parent material, welded joint, construction, etc.
• The treatment process should comply with product standards and requirements.
• Heat treatment must be recorded to demonstrate adherence to specifications and be traceable to the specific product.
• Documents required for confirming conformity to quality requirements for post-weld heat treatment are listed in tables 6 and 10 of ISO 3834-5:2005 for arc welding, electron beam welding, laser beam welding, and gas welding and other fusion welding processes respectively.

Non-Destructive Testing

• Documents relevant for confirming conformity to quality requirements for non-destructive testing are stated in tables 9 and 10 of ISO 3834-5:2005 for arc welding, electron beam welding, laser beam welding, and gas welding, and other fusion welding processes respectively.

Identification and Traceability

• If required, identification and traceability of the manufacturing process must be maintained.
• Documented systems for ensuring identification and traceability of welding operations must include information on identification of production plans, routing cards, weld locations, non-destructive testing procedures and personnel, welding consumables, parent material, locations of repairs, temporary attachments, welds for fully mechanised and automatic welding units, welders and welding operators, and WPS.

Quality Records

• Quality records must include documents outlining requirements, technical review, material inspection, welding consumable inspection, WPS, equipment maintenance, WPQR, welder or welding-operator qualification certificates, production plan, non-destructive testing personnel certificates, heat-treatment procedures, non-destructive and destructive testing procedures and reports, dimensional reports, repair records, non-conformance reports, and other relevant documents.
• Quality records must be preserved for a minimum of five years unless otherwise specified.

ISO 3834-2:2005

• This document covers the quality requirements for welding, focusing on technical review, sub-contracting, personnel requirements, equipment, welding consumables, storage, post-weld heat treatment, inspection and testing, non-conformances, calibration, identification and traceability, and quality records.
• Technical review requirements include evaluating parent material specifications, welded joint properties, accessibility for inspection and testing, welding procedure, non-destructive testing, and heat treatment procedures.
• Sub-contracting requires manufacturers to provide subcontractors with information and records of their work.
• Welding personnel qualifications are required for all welders, with the exception of visual testing.
• Non-destructive testing personnel qualifications are required for all personnel except for visual testing.
• Equipment requirements include power sources, joint and surface preparation equipment, preheating and post-heat treatment equipment, jigs and fixtures, cranes, personal protective equipment, ovens, and surface cleaning facilities.
• Destructive and non-destructive testing facilities are required for all manufacturers.
• Welding consumable control is required for all manufacturers and includes procedures for storage, handling, identification, and use of welding consumables.
• Parent material storage must protect material from damage and maintain identification throughout the storage process.
• Post-weld heat treatment requires manufacturers to document procedures that comply with established standards.
• Inspection and testing includes all necessary quality control processes and requirements.
• Calibration and validation of all measuring, inspection, and testing equipment is required to ensure accurate testing results.
• Identification and traceability processes ensure the correct identification of production plans, routing cards, weld locations, non-destructive testing procedures and personnel, welding consumables, parent material, repair locations, and temporary attachments.
• Quality records are required for every relevant step of the manufacturing process and must be retained for a minimum of 5 years.
• Welding procedure qualifications are required where specified and documented.
• Welding consumables batch testing is required only where specified.
