BS EN ISO 9606

BS EN ISO 9606 is an international standard that specifies how to qualify welders for fusion welding. It's used for critical applications such as pressure vessels, bridges, and structural steel work.

What's in BS EN ISO 9606?

• Part 1:Qualification testing for welding steels
• Part 2:Qualification testing for aluminium and aluminium alloys
• Part 3:Approval testing for copper and copper alloys
• Part 4:Approval testing for nickel and nickel alloys

How does it apply?

• BS EN ISO 9606 applies to welders in construction, automotive, mechanical, and aerospace industries

• It also applies to sheet metal manufacturers and pressure vessel manufacturers

How do welders maintain their status?

• Welders must have their coding certificate signed every six months by a qualified person
  
  

• They must be re-tested at least every two years
  
  

How are welds tested?

• Welds are often subject to volumetric inspection, such as radiography or ultrasonic examination
