High-quality welding connections are a key element in the production of mechanical components used in a variety of industries – from machinery and energy, to defense, to automotive, construction and many others. The durability and strength of finished components depend not only on the technologies used, but also on the compliance of the welding process with strict standards.
At SIM Gdynia, we use proven procedures that produce repeatable and durable joints that meet the highest industry requirements – regardless of the sector in which they are used.
Standards governing welding processes
In order for welding processes to comply with technical requirements and meet specific strength criteria, it is necessary to apply standards governing metal joining technology, welder qualifications and quality control methods. Of particular importance in the manufacture of mechanical components are:
- EN ISO 15614-1, which specifies requirements for qualifying welding technology. Each method must be confirmed by strength tests and material structure analysis to ensure the durability of the weld under operating conditions.
- ISO 9606-1, which regulates the qualification of welders. To guarantee the high quality of the connections made. Those carrying out the process must have the appropriate certifications to prove their skills.
- EN ISO 9712, concerning non-destructive testing (NDT) methods used to evaluate the quality of welds in components subjected to high mechanical loads.
- DNV (Det Norske Veritas) and BV (Bureau Veritas) certifications, required in sectors with high quality and safety standards, such as the marine, offshore and energy industries.
At SIM Gdynia, we attach great importance to adhering to the above standards, which allows us to provide mechanical components with high durability and compliance with customer requirements. Our processes are supervised by certified specialists and are subject to systematic verification to ensure that each weld meets stringent quality standards.
Welding technologies used in the production of mechanical components
TIG welding (141) – precision and heat control
TIG (141) welding produces high-quality and precise welds. By using a tungsten electrode and shielding gas, the process minimizes the effect of heat on the structure of the material. This technology makes it possible to obtain clean and aesthetically pleasing welds, which is crucial for parts with increased corrosion requirements.
MIG/MAG welding (135/136) – durability and efficiency
MIG/MAG (135/136) welding is used in joining low-alloy steel, where the strength of the joint and resistance to dynamic loads are crucial. This process makes it possible to achieve durable welds while maintaining high production efficiency.
Materials used in the welding process
In the production of mechanical components, it is crucial to use the right materials, which must meet the requirements for mechanical strength, resistance to external factors and compliance with technical documentation.
At SIM Gdynia, we weld both stainless steel, which requires precise control of thermal parameters to avoid overheating and structural changes, and low-alloy steel, used in machine structures and components subjected to intensive mechanical loads.
Summary
Professional welding services in the production of mechanical components must meet the stringent requirements of EN ISO 15614-1, ISO 9606-1 and EN ISO 9712 to ensure the durability and precision of joints. At SIM Gdynia, we ensure that each process is carried out to the highest standards, allowing us to deliver components that meet the expectations of customers in a wide range of industries.
Thanks to the use of certified procedures, we are able to carry out both single projects and larger series. Constant quality control and supervision by an experienced team guarantee that each weld is made with the highest precision and in accordance with the technical documentation.
