⇒ Welding Coordination Staff (IWE, EWE)

Our welded manufacturing practices are carried out by qualified personnel who have international welding engineering certificate. It is responsible for the preparation of resource planning, guiding the welding personnel and keeping the resource records.

​

 

⇒ Welding Procedure Procedure and Specification (WPQR, WPS)

Welding works by Simetrik Engineering are carried out according to the standard welding procedure procedures and specifications. The prepared welding procedure procedures and specifications are submitted to the customer for approval before production and after the approval, the production is started.

​

 

⇒ Certified Welding Personnel in accordance with International Standards (WPQ)

Welded works are carried out by our certified personnel under the supervision of our welding coordination personnel. Our welding personnel are certified by our welding engineers within the scope of international standards or by our certified engineers.

​

 

⇒ Quality Control Plan (ITP)

To meet customer and standard requirements and to determine control and test steps by Symetrik Engineering, quality control plan is prepared and submitted to customer approval. Symmetrical Engineering performs manufacturing according to approved quality control plan.

​

 

⇒ Material Acceptance and Traceability

All kinds of main materials and consumables stored for use in the project have been checked after conformity with the product standard and material acceptance is realized. Defective materials which are not suitable for the standard are recorded and returned. Material traceability during manufacturing is carried out according to the requirements of the relevant standards.

​

 

⇒ Before and After Welding Inspections / Records

Our welding operations are recorded according to the steps mentioned in the quality control plan at the relevant stages of production. Pre-weld measurement and roof control, post-welding visual and non-destructive examinations are applied. From these records, it is aimed to continuously improve the welding quality and the performance of the welding personnel.

​

 

⇒ Post-Welding NDT Applications (VT, PT, MT, RT etc.)

Non-destructive tests according to customer or standard requirements after welding are performed by authorized institutions and personnel.

​

 

⇒ Calibration and Periodic Controls

All kinds of equipment used in manufacturing (measurement, welding, test, etc.) have the necessary periodic maintenance and calibration certificate. It is aimed to realize quality manufacturing with suitable equipment.

​

 

⇒ Quality File

For the projects completed, a quality file is created to be given to the customer. All recorded documents and documents are kept in the quality file.
