Study Notes

ISO 3834-2:2005(E) - Comprehensive Quality Requirements

Defines comprehensive quality requirements for fusion welding of metallic materials.
Applies to both workshops and field installation sites.
Includes normative references to ISO 3834-1, ISO 3834-5, and relevant documents specified in ISO 3834-5 for different welding processes.

Review of Requirements

Manufacturer should review contractual requirements, technical data, and ensure sufficient resources for production.
Variations between contract and previous quotes should be identified and communicated to the purchaser.
Review focuses on:
- Product standard and supplementary requirements
- Statutory and regulatory requirements
- Manufacturer's capability to meet the prescribed requirements

Technical Review

Typically conducted during the initial planning stage.
Includes:
- Design analysis: ensuring the design is suitable for welding and the welding process meets requirements.
- Material selection: appropriate material selection for welding process and performance.
- Welding procedures: establish and document procedures based on WPS (welding procedure specifications).
- Non-destructive testing method selection: includes procedures and acceptance criteria.
- Control of manufacturing processes: includes quality control measures, inspection, and testing.

Non-destructive Testing Personnel

Non-destructive testing personnel should be qualified with the exception of visual testing where competence can be verified by the manufacturer.

Equipment

Essential equipment for production and testing includes:
- Welding power sources and machines
- Equipment for joint and surface preparation, cutting, and thermal cutting
- Preheating and post-heat treatment equipment
- Jigs, fixtures, cranes, and handling equipment
- Personal protective equipment
- Facilities for surface cleaning
- Destructive and non-destructive testing facilities

Description of Equipment

Manufacturer should maintain a list of essential equipment including:
- Crane lifting capacity
- Component size limitations
- Capabilities of mechanized or automatic welding equipment
- Furnace dimensions and temperatures for post-weld heat treatment
- Capacities of rolling, bending, and cutting equipment

ISO 3834: Introduction

ISO 3834 is a series of international standards that specify quality requirements for fusion welding of metallic materials.
ISO 3834-1 serves as a guideline for selecting the appropriate level of quality requirements based on the three levels specified in ISO 3834-2, ISO 3834-3, and ISO 3834-4.
It applies to both workshop and field installation manufacturing.
Each part of ISO 3834 focuses on a specific aspect of fusion welding quality.
ISO 3834-5 outlines necessary documents for claiming conformity to the quality requirements of ISO 3834-2, ISO 3834-3, or ISO 3834-4.
ISO 3834 does not define requirements for a total quality management system, but Clause 6 highlights complementary quality management system elements.
Manufacturers can use ISO 3834-2, ISO 3834-3, and ISO 3834-4 independently or alongside ISO 9001:2000.

ISO 3834-1: Scope

ISO 3834-1 provides criteria for choosing the right level of quality requirements for fusion welding of metallic materials.
It encompasses various manufacturing settings: workshops and field installation sites..
ISO 3834-1 does not cover requirements for a total quality management system but connects to relevant elements defined in Clause 6.

ISO 3834-1: Normative References

ISO 3834-1 relies on the standards ISO 9000:2000, "Quality management systems — Fundamentals and vocabulary", for its application.

ISO 3834-1: Terms and Definitions

Refer to both ISO 9000:2000 for general definitions, and specific definitions outlined in ISO 3834-1.

Permanent Visual Records of Welds

Permanent records of inspected welds can be made using photographs, sketches, or both.

Annex A: Examples of Test Equipment

This annex provides examples of test equipment used for inspecting welds.

Measuring Equipment

A straight edge and measuring tape can be used to measure the length of welds.
A vernier caliper, described in ISO 13385, can be used to measure the width of welds.
A feeler gauge, used for measuring gaps, can be used for measuring gaps in welds up to 3mm in increments of 0.1 mm.
A radius gauge can also be used for measuring the radius of welds.
A magnifying lens, described in ISO 3058, with a magnification of 2x to 5x can assist in inspection.
Lamps can be used to illuminate the weld for better inspection.

Materials used for Impressions of Welds

Smooth, rounded surfaces can be used to make an impression of a weld for a more accurate inspection.
Materials like soft metals, plastics, or wax can be used to take an impression of a weld.

Other Measurement Devices

In addition to the listed equipment, other common measurement devices like rulers, protractors, angle gauges, and calipers can be used to measure different weld aspects.

Table A.1: Examples of Gauges

The table outlines the capabilities of three different types of gauges for inspecting welds: three-scale weld gauge, gauge for checking the root opening of a weld, and multi-purpose gauge.
The three-scale weld gauge, with a scale from 0 to 15, can measure the throat thickness, leg length, and reinforcement of a butt weld. It is suitable for inspecting butt welds.
The gauge for checking the root opening of a weld is specifically designed to measure the root opening of a weld.
The multi-purpose gauge can measure the angle of bevel, leg length, misalignment, throat thickness, and weld reinforcement.

Testing and Inspection of Welds

ISO/TC 44, Subcommittee SC 5 is responsible for this document.
The document focuses on testing techniques for welds.
Techniques are suitable for various welding processes and joint types.
Prior to testing the following information is crucial:
- Parent and weld materials type and designation
- Welding process used
- Welds to be tested - location and extent
- Joint preparation and dimensions
- Details of any repairs
- Post-weld treatment (if applicable)
- Surface conditions

Destructive Tests on Welds in Metallic Materials

The document outlines standards for destructive tests of welds in metallic materials.
The examination of welds can be performed macroscopically or microscopically.
The standards covered are:
- ISO 17639:2003
- EN ISO 17639:2013
The document supersedes EN 1321:1996.
Test specimens are generally positioned perpendicular to the weld axis.
The location, orientation, and number of test specimens should be agreed upon prior to the test.
The table provided outlines guidelines for assessing features by microscopic and macroscopic examination.
The table includes features such as:
- Hot cracks
- Cold cracks
- Lamellar tearing
- Cavities
- Inclusions
- Lack of fusion/penetration
- Geometrical shape
- Heat affected zone
- Runs and layers
- Grain Boundary
- Grain structure
- Solidification structure
- Joint preparation
- Direction of rolling/extrusion
- Direction of fiber structure (grains)
- Segregation
- Precipitation
- Repair and non-conformance
- Mechanical/thermal effects
The table identifies which features are revealed by each type of examination (macroscopic with/without etching and microscopic with/without etching).

Standards for Welding and Allied Processes

The document lists other relevant ISO and DIN standards related to welding processes.
The standards include:
- ISO 6520-1 (Classification of Geometric Imperfections)
- ISO 9956-3 (Arc Welding of Steels)
- ISO 9956-4 (Arc Welding of Aluminum and its Alloys)
- ISO/TR 15608 (Metallic Material Grouping System)
- ISO/TR 16060 (Etchants for Macroscopic and Microscopic Examination)
