How Do We Define Coded Welding or Code Welding?

Promotional Bundle Offer
The term "Coded Welding", ''Code Welding'' or "Welding Codes" means that the person who says he or she is a "coded welder" has taken an exam in a welding process using a certain method. (Welder Approval Test)Think of it as a bit like learning to be a pilot. Once you have qualified as a pilot you then have to take type approval tests to be able to fly different types of aeroplane.

The same applies to welding codes. If you wanted to work for a company who installed stainless steel tubing in factories then you would probably train for a coding using TIG welding for stainless steel tube in an all postion  6G configuration. You need to consider 1.Process. 2.Material. 3.Thickness. 4.Type of joint.5.Position (Difficulty). Usually 1G is the easiest and 6G the hardest.

My own codings are in MIG and MMA(stick), Mid steel plate in the vertical up position.

Some examples of the processes are:

 Process Material   Thickness Joint type   Position
 MIG Mild steel  12mm  Butt weld  Vertical up 3G  1
 MMA(stick)  Mild steel 10mm  Fillet weld  Horizontal 1G  2
 TIG S/S   3mm Inclined pipe   All position 6G

Verticle Position MIG Process         Horizontal Position MMAStick Process         All Position TIG Process

Usually, the simpler joints are easier to master and as you progress up the ladder, the trickier joints will allow you to be coded in the easier joints automatically so try and get coded in the higher levels if you can.

The hardest joint is usually the inclined plane pipe to pipe weld. This will usually cover all the easier joints as well.

There are several welding codes around such as BS 4872, BS EN 287-1 ,ASME IX and now EN ISO 9606-1
The ASME IX (pronounced as "asmey nine") is the American qualification and usually applies to an inclined pipe joint.
The BS 4872 is as the name suggests is the British Standards qualification and usually refers to plate work or beam welding joints in the construction industry.
The BS EN 287-1 is a European standard and is relevant in machinery and industry. It is accepted as the European equal of the ASME IX qualification and it should get you a job in welding the world over however it has now bee superseded by EN ISO 9606-1

I regularly get asked how to achieve the coding to allow a person to go off shore and work on oil rigs etc.
Well, the answer usually goes along these lines......

If you would like to work out on oil rigs you will have to start off "learning to walk before you can run."
You will usually need BS EN 287-1 (now EN ISO 9606-1) or ASME IX to work off shore and usually in "stick" welding.
Don't be put off though as you can learn to stick weld quite quickly and achieve good results.

Learn to stick weld first rather than MIG weld as the "MIG" welder is usually shore based in a fabrication workshop.
The nature of stick welding lends it's self to off shore work as it is far more versatile in an environment out at sea. MIG welding relies on the principle that the welded joint is shielded by a gas which tends to be blown away in windy conditions.
Once you have got the hang of stick welding you could try and get a job in a workshop and improve your skills,branching into MIG welding as an extra. It's much easier to get time and experience once you are "on the inside".
Employers are usually keen for their staff to improve themselves and might let you have one day per week attending a college on a welding course. As in any trade, there is no substitute for experience.
 You can learn so much more if you are working within the trade rather than just attending a training course. Work colleagues are usually very keen so show you their tips and techniques so pick their brains at every opportunity.
You will soon be knocking out welds as good as them!
This is the stage you might want to consider starting to train towards a coding.
 Some larger companies may have "in house" training courses so seek them out and get all the training you can. Their welder training will probably be conducted by "real" welders on the shop floor who have had a lifetime of practical skill and experience.
They can teach things that your average college welding teacher doesn't even know about.

Although MIG coding is useful, try to get stick welding coding if you can as this is required off shore.

Other training options are attending welding courses that are offered by specialist welder training companies. Beware of these companies though as they might charge you a fortune for a short course and then say at the end of it that they think you are not quite ready and should pay for another short course........... Not all of them though!
Obviously, the time taken to achieve a coding will ultimately depend on the ability of the individual.
Welding is a bit like driving. It will become second nature with practice so
Practice  Practice  Practice.
