CERTIFICATION

It is the examination of the parameters affecting the quality such as discontinuities on the surface of a product, structural defects, surface condition, with or without the use of an optical aid (such as a magnifying glass).

EN ISO 3834 WELDED MANUFACTURING CERTIFICATION

Welding is used in many sectors (in shipbuilding, pressure equipment, steel constructions, railway vehicles and components, in the creation of auxiliary vehicles and carrier systems) to reveal structures that cannot be manufactured as a single piece. used) is a special manufacturing method. It is defined as a special process in ISO 9001, which is the most widely accepted and applied standard in the world.
EN ISO 3834 serial standards are the standards that define all the Quality conditions necessary for the operation of this special process.
As with all other standards, the quality of a product according to EN ISO 3834 must be ensured during manufacture, not inspection. For products that are free from problems in manufacturing and service conditions, controls must be provided at the design stage, from material selection to post-manufacturing inspections. For example, poor design can create serious and costly problems in the workshop or in the field. Incorrect material selection or unfavorable welding conditions may cause cracks in welded joints. To ensure robust and effective production, management needs to know potential sources of problems and implement appropriate quality procedures. EN ISO 3834 specifies the measures that can be applied for different situations. These measures are used in the following cases
In case of contract or tender; as the specification of welding quality requirements; For the establishment and maintenance of quality welding conditions by the manufacturers; It can be used by organizations evaluating welding quality performance for third party, customers, or manufacturers. EN ISO 3834-2, as detailed, standard and basic quality conditions in terms of the scope and importance of safety critical products, the complexity of production, the range of use of the manufactured products, the scope of metallurgical problems that may occur, the scope of manufacturing defects that will affect product performance such as eccentricity, distortion or welding defects, It is documented in quality levels as EN ISO 3834-3 and EN ISO 3834-4.

EN ISO 3834 is not a stand-alone standard, it is a group of standards consisting of 5 standards.
– EN ISO 3834-1: Criteria for selection of the appropriate level of quality requirements,
– EN ISO 3834-2: Comprehensive quality requirements,
– EN ISO 3834-3: Standard quality requirements,
– EN ISO 3834-4: Basic quality requirements,
– EN ISO 3834-5: Documents required for confirmation of compliance with quality requirements.

INTERNATIONAL STAFF CERTIFICATION AND WELDERS CERTIFICATION INFORMATION

The production quality of all kinds of products and the sustainability of the enterprise depend on the competence and competence of the personnel involved in that process. In many production processes, the most important process is the production of skid parts, in this direction, the welding process is a special process, but it also requires the most critical controls and precautions.
