A coded welder is someone who has completed a Welder Approval Test to a specific welding configuration.
The method of welding all depends on the job in hand, some welding codes can be very specific while some are more general.
Coded welding is done to BS EN standards in the UK while the USA uses the ASME IX standard. A welding specification is provided for the job, this is used by the welder to provide a sample which matches the welding to be completed.
The sample is examined by an approved tester to see if the welder can complete the job, if the welder passes then they are coded to that specification.
Each specification must be coded separately, being qualified in one specification doesn’t necessarily mean you’ll be coded in another. To become a multi-coded welder each specification requires testing and examining.
Coded Welding Training
The training for coded welding must be fully UKAS approved in the United Kingdom and is usually carried out by insurance certified individuals.
There are different levels of coded welding training everything from college level right through to more advanced certifications. Standards are set by the governing body for welding in the UK these include: ASME IX, BS EN ISO 9606 – 1/2, BS4872 – 1/2 and ISO 15614-1.
Many different types of welding are used in industry to produce products. MMA (Manual Metal Arc), TIG (Tungsten Inert Gas), MIG (Metal Inert Gas) and FCAW (Flux Cored Arc Welding) are the most types of welding used today.
