A coded welder is someone who has completed an approved test for a specific welding job. In the United Kingdom welding approval codes are done to ISO standards, in the USA the ASME IX standard is used.

The welder working on the job provides a welding sample that matches the work being carried out. This is then examined by a qualified tester to check the capabilities of the welder. If the welder passes, then they are coded to that specification.

Each specification has its own code and being coded in one doesn’t necessarily mean you’ll be coded in another. Training, tests and examination are all required to become a multi-coded welder.

Different Types of Welding

There are a few different types of welding used in industry today, each requiring their own skillset to be completed at a competent level.

TIG – This type of welding is also known as Gas Tungsten Arc Welding (GTAW) and is commonly used where high-quality welds are required.

MIG – This type of welding is also known as Gas Metal Arc Welding (GMAW). MIG is the most common type of welding process currently used in industry. This type of welding can also be used for a variety of metals and alloys.

MMA – Commonly referred to as stick welding this process is very low-cost and can be used anywhere. This process can be used on a variety of materials.

Fusion Welding – Gas and water pipework is where this welding process is commonly used. Heat and copper wire are used to fuse the ends of the pipe together.

These are the most common types of welding which you can get coded for.

Training courses are available to get further experience ready for any coding examinations you wish to take.
