Quality requirements for fusion welding of metallic materials
Welding, ISO 3834, 1090, 15085 Consultancy
In terms of quality, welding is considered a special process, which means that it’s not readily verified. For its successful application, you will need specialist management, procedures, personnel, and welding equipment that go way beyond the typical quality systems. It is such requirements that have led to the development of the ISO 3834.
The ISO 3834 is a standard that defines the quality requirements which are suitable for fusion welding processes of metallic materials, applicable to welding both in the workshops and on-site. It is a notable requirement that proves a manufacturer can produce welded constructions that meet specified criteria. The standard takes into account that quality should be built into a product. For this reason, making a high quality welded product that will be effective in use requires control to be taken seriously right from the initial stages. The ISO 3834 provides requirements that manufacturers have to meet in order to apply the best practices to their welding processes.
There are several steps involved in the welding quality assurance. For instance, the welding workshops need to ensure their welders are highly qualified and competent. With that said, there are also standard ways to test the skill level of the welders. In addition, whenever necessary, you might have to use written welding instructions and the Welding Procedure Specifications (WPS) to increase the chances of consistency in quality. The welding coordinator is considered responsible for the competence, education, and management of the welders.
A company that is ISO 3834 certified is identified as reputable and trustworthy. That’s why it is vitally important for welding companies to implement the Welding Quality Assurance System. Aaron Solutions is a leading certification body in India that offers services such as certification of welders, certification of welding shops or companies, and the qualification of welding procedures.
EN 15085 and EN 3834 certification consultancy
Quality is a key consideration in the manufacture of railway vehicles and all their components. It becomes even more important for the manufacturer involved in railways, and there must be an assurance to the welding process. The requirements for the process are stipulated in the standards EN ISO 3834. This standard has all the set requirements, processes, and assessment procedures of the railway vehicles and components manufacturers by welding for compliance in accordance with BS EN 15085-2.
BS EN 1090
Welding deals with steel and aluminum structures and this is where the BS EN 1090 comes into play. Fabricators require the CE marking and to get that, they must comply with EN 1090 parts 1, 2 and 3. EN 1090 part 1 requires manufacturers to document and implement a Factory Production Control system and have it certified by an accredited body.
EN 1090 part 2 involves technical requirements for the steel structures. It defines the requirements for the steel frames to meet efficient levels of durability stability, and mechanical resistance. EN 1090, part 3 involves the execution of steel and aluminum structures. It also defines technical requirements for aluminum structures.
