ISO 3834-2 is an international standard developed specifically for companies engaged in welded manufacturing, detailing the quality management requirements throughout the welding processes. This certificate ensures that every stage—from planning and application to control and documentation—is carried out with a high level of quality assurance.
The welded manufacturing sector demands high precision and reliability due to the critical importance of product durability and safety. Therefore, compliance with standards at every step of welding operations is essential. ISO 3834-2 systematically defines these quality requirements to meet industry needs.
The standard integrates both technical and managerial processes involved in producing welded products. Key aspects such as welder qualifications, material inspection, equipment calibration, production environment conditions, and quality control mechanisms are thoroughly assessed within this framework.
Holding the ISO 3834-2 certificate helps welded manufacturing firms gain credibility and competitive advantage in international markets. It provides official proof to customers that the company delivers high-quality production in accordance with global standards.
At Kioscert, we offer expert consultancy, process management, and documentation support throughout the ISO 3834-2 certification process, helping companies effectively implement quality management at every stage of welded manufacturing.
Which Companies Does ISO 3834-2 Cover?
ISO 3834-2 is a part of the ISO 3834 series that defines quality requirements for fusion welding of metallic materials. Specifically, ISO 3834-2 sets the criteria for comprehensive quality requirements and is applicable to companies that demand a high level of quality control in their welding operations.
The standard is relevant to companies involved in welded manufacturing across a broad range of industries, but it is particularly essential for firms whose products are subject to safety-critical and high-performance applications. These include sectors such as heavy machinery, automotive manufacturing, shipbuilding, construction engineering, energy production (including oil, gas, and renewable energy), and aerospace.
Furthermore, ISO 3834-2 is mandatory for organizations manufacturing structural steel elements that will be subject to strict regulatory requirements or certification, ensuring their welds meet stringent technical and safety standards. The standard helps companies demonstrate due diligence in controlling welding processes, from personnel qualification to welding procedure specification and final inspection.
Importantly, ISO 3834-2 is scalable and adaptable, making it suitable for a variety of company sizes—from small specialized welding workshops to large industrial manufacturing plants. For smaller companies, it provides a structured approach to meeting quality requirements efficiently. For larger enterprises, it supports complex welding projects with multiple welding methods and extensive production volumes.
Kioscert specializes in assisting companies throughout all phases of the certification journey, offering customized consultancy to align company processes with ISO 3834-2 standards. This guidance ensures companies gain and maintain compliance, resulting in enhanced product safety, customer trust, and competitive advantage.
Usage Together with EN 1090
EN 1090 is a European standard that specifies requirements for the execution of steel and aluminum structures, including the conformity assessment of structural components. It plays a critical role in construction and infrastructure projects by defining the technical requirements for design, fabrication, and installation of load-bearing metal components.
While EN 1090 focuses primarily on the structural and mechanical aspects of steel and aluminum assemblies, ISO 3834-2 targets the quality management of the welding processes involved in producing these assemblies. The welding process quality is a key factor that affects the overall integrity and durability of the final product.
Together, these standards form a comprehensive quality framework: EN 1090 ensures that structural components meet design and safety specifications, while ISO 3834-2 guarantees that welding processes meet stringent quality and procedural controls.
In sectors such as construction, heavy industry, and infrastructure, applying both standards concurrently minimizes risks, reduces rework, and ensures compliance with international regulatory requirements. This dual compliance enhances customer confidence and facilitates market acceptance, especially within the European Union.
Kioscert provides extensive support to organizations aiming to comply with both EN 1090 and ISO 3834-2, offering expert consultancy, training, and auditing services tailored to the specific needs of each company.
Technical Requirements in the Certification Process
The technical requirements in the ISO 3834-2 certification process encompass a comprehensive and systematic control of all welding operations to ensure quality in the welded manufacturing sector. These requirements mandate the establishment of a management system that covers every stage of the welding process, from methodology selection to welder competency assessment, written welding procedures, and ensuring full compliance with standards during execution.
The first step in technical compliance is planning the welding process. This includes detailed determination of welding methods to be used, materials to be processed, and how process parameters will be controlled. Additionally, technical specifications and quality criteria for the products to be welded must be clearly defined.
During certification, welder qualifications and training records are thoroughly reviewed. Welders are expected to hold internationally recognized certifications and maintain up-to-date knowledge of current standards through regular training. This is a critical factor for ensuring consistent welding quality.
Equipment calibration and maintenance processes are also key technical requirements. Welding machines and measurement devices must be calibrated at specified intervals to guarantee accurate and reliable welding operations. Furthermore, production environment conditions—such as temperature, humidity, and cleanliness—are evaluated.
The implementation of welding procedures is verified through inspections and tests. These include visual inspection of weld seams, non-destructive testing (such as ultrasonic and radiographic tests), and mechanical testing. Product compliance with quality standards is approved based on the results of these examinations.
Documentation and traceability constitute one of the most critical technical requirements of ISO 3834-2. Welding reports, material certificates, calibration records, and training documents must be complete and up-to-date. These documents serve as proof of quality management during audits.
At Kioscert, we guide companies through every stage of these complex technical requirements, ensuring processes progress accurately and comprehensively. This enables firms to successfully achieve ISO 3834-2 certification and uphold high-quality standards in welded manufacturing.
