  • Unalloyed and low alloyed steels (S235, S355, P235, P265)
  • high-strength fine grained structural steel to grade S690QL (Weldox)
  • stainless chrome nickel steels (V2A, V4A)
  • aluminium and aluminium alloys (AlMg3)


We have been awarded the following approvals:

  • DIN EN ISO 3834-2
  • DIN EN 15085-2, certification level CL1
  • DIN 2303 – class Q2, structural component class BK1
  • Approval according to GL regulations for the following areas of application:
  • Welding of pressure vessels
  • Welding of piping / orbital welding 
  • Welding of machinery constructions and components 


Our team includes qualified welders for: 

  • Manual metal arc welding
  • WIG-welding
  • MIG-welding
  • MAG-welding


Experienced welding engineers, welding instructors and welding experts supervise the particular requirements and assure the optimal quality of welding connections at TASCO. All non-destructive tests are carried out when needed.

  • Visual inspection (VT)
  • Dye penetrant testing (PT)
  • Magnetic particle testing (MT)
  • Ultrasonic inspection (UT)
  • X-ray inspection (RT)


In order to meet the highest standards and to satisfy the most stringent customer requirements with regard to performance and quality, at TASCO we emphasize continuous training and education of our staff.
