WELDER CODING – BS 4872 Part 1 & 2 Welder Coding

The welder coding tests for BS EN 4872 part 1 and part 2 applies to a wide range of general fabrication work where an approved welding procedure is not required. You will produce a weld following written instructions, and then the welded joint is subject to visual or surface inspection, as well as a destructive bend test, nick break fracture test and macro etch.

This is a UK welding standard (British Standard 4872) is used to certify all welding positions on a sheet, plate and pipe for mild steel and aluminium using for the four welding processes. You will choose one ARC welding process, including a MIG Welding coding (GMAW), MAG welding coding (GMAW), TIG welding coding (GTAW), Flux cored welding coding (FCAW).

You are given no more than 120 minutes to complete the test if you require training before the test, then please use the welder coding training course before the test.

You will gain the welding certificate on successful completion of the weld and passing the destructive testing. The process usually takes two days until sign off and posting of the certificate

What is the BS EN 4872 Part 1 and Part 2 Welder Coding?

In less demanding situations, such as small to medium building frames and non-structural work, an approved welding procedure may not be necessary. However, to ensure an adequate level of skill, welders are often recommended to a less stringent standard such as the BS 4872 Welder Coding.

The BS 4872 welder coding certification offers a measure of competence to people who are using welding for maintenance or as a small part of their job role.

How does the BS 4872 Welder coding Work?

You will produce a weld following written instructions, and then the welded joint is subject to visual or surface inspection, as well as a destructive bend test, nick break fracture test and macro etch.

This is a UK welding standard (British Standard 4872) that can be used to certify all welding positions on a sheet, plate and pipe for mild steel and aluminium using for the four welding processes. You will choose one ARC welding process, including a MIG Welding coding (GMAW), MAG welding coding (GMAW), TIG welding coding (GTAW), Flux cored welding coding (FCAW).

You will be given no more than 120 minutes to complete the test if you require training before the test, then please use the welder coding training course before the test.

BS EN 4872 part 1&2 Weld Test Requirements

Depending on the particular weld configuration, each test can cover a range of welding variables, for example, material thickness and welding positions. You will be coached on the standard before the test so that you fully understand the requirements of the coding.

How Long Does The Certificate Last?

Welder coding certificates must be signed every six months by a suitably qualified person to confirm the welder is still producing welds of the required standard. You must be formally re-tested at least every two years. Note that this is the price for the test only. If you need training as well, then please look at the Welder Day training.

Frequently Asked Questions

What is a Coded Welder?

A coded welder is a terminology used for an approved welder. The qualification or standard you are approved for will not mention the term coded welder.

The name coded welder is a technical term to describes a time served and skilled welders. Who will have completed a welder approval testing to a specification or standard such as ASME IX?

For the UK approvals are conducted to BS EN ISO standards and for the  USA the ASME IX and AWS standard.

How long do welder or welding codings last?

Welder coding certificates must be signed every six months by a suitably qualified person to confirm the welder is still producing welds of the required standard. You must be formally re-tested at least every two years to ensure a continuity log.

What do welders earn the UK?

For a welding apprentice, the starting hourly rate is usually set at or just above national minimum wage, for a welder that is starting a career after an intensive induction course such as our intermediate programme the starting salary ranges for 13-16 per hour. For experienced welders, that sky is the limit; however, it really depends on market conditions and your experience. Welding is a real skill, and it comes with time on the job. You will need to earn your stripes to get well paid in welding.

What colleges are good for welding and Where can I get welding certification?

If you are looking for an apprenticeship or intensive welding training to gain employment fast, then look no further than TWA Certifications Ltd the 4.9 stars rated Welding College in the UK. We operate from our welding test location of Chester, Cheshire that has a vast range of hotels and Airbnb accommodation. All our programmes are practical and are delivered by an intensive teaching method.

What qualifications does a welder need?

This is a difficult question to answer as we meet lots of welders that have been welding for 20 years plus without qualifications. However, with the industry moving towards more regulation, welders are seeking qualifications to prove competence and to gain employment.  You will need some form of assessment and certification to prove your competence. There are lots of ways to demonstrate proficiency:

  • Time Served Apprenticeship
  • City and Guilds qualifications at Beginners, Intermediate and Advanced Awards, diplomas and NVQs
  • Welder Competence Certification
  • British Standard 4872 Class 2 Welder Coding Qualification
  • ASME IX Class 1 Welder Coding Qualification
  • ISO 9606 Class 1 Welder Coding Qualification

What is ASME, ISO 9606 Welding code or standards?

In short, these are the quality standards that the welding procedure is written to meet and that welders are tested against. When you have followed a welding procedure that has been written to meet one of these standards and the weld has been tested using NDT and DT methods (non-destructive and destructive testing then you will be a coded welder.

What is 6g coded welding?

This usually refers to welding pipe in the 6g position. Click the link to see the different positions in welding. 6g is thought to be a difficult and awkward position, and when you are coded in the 6g position, it covers you for a multitude of less difficult welding positions. You can be coded in 6g using BS 4872, ASME IX or ISO 9606 standards.

What is ASME coded welding?

This refers to someone who has been tested against the ASME IX standard, and the Welded joint has past destructive tests and the Xray (bomb). The welder could be referred to as welding at ASME standard or an ASME coded welder. For more information on coded welding, please click this link.

Who issues welding certification?

It depends on the qualification, but they include, City and Guilds, The Welding Academy, TUV, LGRWC, Zurich and TWI.
