Welding certification is required for anyone who wants to work as a professional welder. A professional welder can find employment opportunities in a wide range of industries, from construction to a production factory. The purpose of welding certification is to validate that all welders have a specific level of skill and training. Safety is a very important aspect of welding, as this trade requires the use of very hot torches.

The first step toward getting a welding certification is to learn proper welding techniques. Short programs in welding are available from community and career colleges. Introductory, intermediate, and advanced welding classes are typically eight to 12 weeks in length. These courses are a combination of theoretical training and hands-on practice with welding equipment.

Many people do not complete a welding program through a post-secondary institution. Instead, they learn this skill on the job. Training is provided by a certified welder, machine mechanic, or related trades person. Practice is required to create a smooth, strong weld. Some employers will allow welders to practice their technique on scrap metal during slow periods.

There is no formal training or experience requirement to get welding certification in the United States. Candidates apply to the American Welding Society® (AWS®) to complete the Certified Welder test. The candidate is required to provide a sound weld for inspection by an AWS® Certified Welding Inspector. This test must be completed at an AWS® accredited testing facility. The weld is evaluated against the welding procedure specification, which includes the fit-up, assembly, and position.

Upon successful completion of the welding certification, candidates are able to work as welders. It is important to note that all certified welders are required to submit a certificate maintenance form every six months. This form must be signed by the employer, confirming that the welder is performing only the welds that he or she is certified for. Candidates who let this certification lapse must repeat the examination.

Career advancement opportunities for a certified welder are quite numerous. Additional certification allows the welder to work in different industries, completing a range of different types of welds. In addition, welders who meet the experience requirements can become certified welding instructors or inspectors. Welding is a lucrative career, providing year-round employment opportunities for skilled candidates.

The welding certification requirements vary by country. In Europe, there is a short course requirement to qualify for the certification examination. Welding is a highly transferable skill, with master welders traveling the world to work on high-profile projects. To qualify for these positions, more advanced welding certification is required.
