Welder / Coded Welder (MIG, TIG, Arc)

What it is

Welding is joining metal with heat. The main hand processes are MIG, TIG and stick (arc) welding, and welders work in fabrication, construction steelwork, shipbuilding, pipework, vehicle repair and manufacturing. A coded welder is one who has passed a formal welding test, a coding test, to a recognised standard such as BS EN ISO 9606 or ASME IX, which proves the welds are safe for critical work.

Who it suits

It suits practical people who are happy working with their hands and can tolerate heat, sparks and heavy metal. It is a trade in steady demand right across the country. Your English does not have to be perfect, but you must understand safety instructions and simple drawings. Once you are coded, it is one of the strongest trades for self-employment and contract work.

How you qualify

1. Learn the basics through a college course (Level 2 or Level 3 in welding or fabrication) or a Welder apprenticeship (Level 2 general, Level 3 pipe or plate), which takes about 2 to 4 years and pays you while you train.
2. Build real experience on the job. Clean, fast welds come from hours at the bench, not from a classroom alone.
3. Sit a coding test (for example CSWIP or a test to ISO 9606) for the position and process an employer needs. Passing this unlocks the better-paid, safety-critical work.
4. Get a site safety card such as the CCNSG Safety Passport for access to many sites.

Cost and how long it takes

An apprenticeship costs you nothing and pays a wage. A college course may be free if you qualify for funding, or a few hundred pounds otherwise. Private coded-welding training and testing typically runs from a few hundred pounds up to around £1,800 for a full package. A coding certificate has to be signed off every 6 months and retested at least every 2 years, so there is a small ongoing cost to stay current. Reaching a solid, well-paid level usually takes 2 to 4 years.

The English you need

You need enough English to follow safety briefings, read simple drawings and understand weld symbols and instructions. That is an everyday working level, not fluent office English. If your English is very basic, welding is still realistic, but take an ESOL course alongside your training so you can pass the health and safety test and understand site rules.

The honest reality

Be careful with adverts promising a "coded welder in a few weeks" for a few thousand pounds. A short course can teach technique and even get you through one coding test, but employers hire on proven experience and a portfolio of good welds, not a certificate alone. Without real time on the tools you will struggle to hold a code or pass a retest. The honest path is simple: learn, weld for real every day, then get coded on the processes your employer actually uses.

What you can earn

As a rough guide, a starter welder earns around £25,000 a year and an experienced welder around £45,000 (National Careers Service figures, estimates only). Coded welders, pipe welders and those doing offshore, site or shift work can earn more, sometimes well over £50,000. Day rates for self-employed coded welders are high. London, the South East and energy projects pay above the national average.

Your next step

If you are new, look for a Welder apprenticeship or a Level 2 college course near you, and if your English is weak enrol on an ESOL class at the same time. If you already weld, focus on getting coded to ISO 9606 or CSWIP on the processes local employers want. Check current fees on the official sites before you pay for anything.
