Welding as a manufacturing process is often an indispensable way of joining of individual metal parts to semi-finished products or finished products, such as load- bearing structures, pressure equipment and machines, transport vehicles etc.
As with any production process, welding requires the achievement of a certain quality of the work performed. The overall quality check of each individual welded joint is practically feasible, but from an economic point of view, it is completely unacceptable for businesses. It is more convenient for companies to establish a system by which mechanisms are created in the production to achieve the required quality of the welding works.
Depending on the criteria (type and complexity of products, a variety of materials and
welding processes used, the complexity of metallurgical problems, etc.), the companies decide on the choice of
quality level in the execution of welding works. It can also be based on production standards, legal regulations,
contractual obligations, various specifications, etc. Standard EN ISO 3834 provides three levels, namely:
- Comprehensive quality requirements (EN ISO 3834, Part 2)
- Standard quality requirements (EN ISO 3834, Part 3)
- Elementary quality requirements (EN ISO 3834, Part 4)
By complying with the requirements of the standard EN ISO 3834, the company establishes the conditions for
achieving a certain quality of welding work in the production, on the basis of certification by an independent
institution and the obtained certificate it can also demonstrate this in its business environment. This not only
increases the trust among business partners but also gives a certain competitive advantage.
