It depends...

Not so much if you are working in a job shop repairing boat trailers and wood stoves.

Quite a bit if you are welding to code; such as pressure vessels, pipelines, structural steel, bridges, nuclear facilities, power generation equipment, etc. To weld on these types of projects you will need to take a welder qualification test (perhaps multiple) and retest many times over the course of your career. Your welds will be inspected by certified professionals who will ensure that your work meets the requirements of the code, specification or contract. Some of your welds may be inspected by Ultrasonic (UT), Radiographic (RT, also known as X-ray) or Magnetic Particle (MT) testing methods to confirm that your welds contain no defects or discontinuities.

Raymond’s Answer

I, myself, am not a wielder. But, I've done a lot of work with them. Wielding needs to be very precise and has to have a complete metal to metal connection. You must remove paint, dirt or anything that can stop the full connection. If you're wanting to get into wielding the best advice I can give is to look into programs in your area that will train you. You could pay for a school or go to your hometowns website to find a company that will pay you as an apprenticeship. It's definitely worth it if it's something you'd like to do. Go melt some metal!

Raymond recommends the following next steps:

Look up the website for your city or town.
Look for a link to apprenticeships. If no link, call the city's number and ask.
Check and see if any close family members or close friends are wielders and ask if they can show you the basics or refer you to someone who can.
