What Does a Welder Do?

Welders join metal parts together using heat, electricity, or gas flames to fabricate and repair everything from steel beams and pipelines to automotive components and aerospace structures. On a typical day, a welder reads blueprints and technical drawings, selects the appropriate welding techniqueโ€”such as MIG, TIG, or stick weldingโ€”and operates equipment to fuse metals with precision. They also inspect completed welds for strength and quality, grind and smooth surfaces, and follow strict safety protocols to protect themselves from heat, sparks, and fumes. Work settings vary widely and can include manufacturing plants, construction sites, shipyards, oil refineries, and automotive shops, with some welders working outdoors in all weather conditions or in confined spaces at significant heights.

Welding suits individuals who enjoy hands-on, detail-oriented work and take pride in craftsmanship, as the role requires steady hands, strong spatial reasoning, and the ability to concentrate for extended periods. Those who are mechanically inclined and comfortable working in physically demanding environments tend to thrive in this career. The minimum required education is typically High school diploma or equivalent, and most welders complete a vocational training program or apprenticeship to build the technical skills employers expect. Job prospects are solid, with consistent demand across construction, manufacturing, and energy sectors as infrastructure projects grow and experienced welders retire. The median annual wage for welders is $47,010, though earnings can rise significantly with specialization in areas like underwater welding or certified pipe welding.

Education & Requirements

1
Complete Basic Education

Obtain a High school diploma or equivalent or equivalent credential, which serves as the foundational requirement for entering welding training programs and apprenticeships in the field.

2
Enroll in a Welding Training Program

After earning your High school diploma or equivalent, enroll in a vocational or technical school welding program where you will learn core techniques such as MIG, TIG, and stick welding in a hands-on environment.

3
Complete an Apprenticeship

Gain real-world experience by completing a formal apprenticeship program, typically lasting 3โ€“4 years, where you work alongside experienced welders and apply the skills learned after your High school diploma or equivalent and technical training.

4
Obtain Welding Certifications

Pursue industry-recognized certifications through organizations such as the American Welding Society (AWS) to validate your skills and improve your employability beyond the High school diploma or equivalent baseline requirement.

5
Advance Your Career Through Specialization

Continue developing expertise by specializing in areas such as underwater welding, aerospace welding, or pipe welding, and consider additional coursework to build on your High school diploma or equivalent and stand out in a competitive job market.

Job Outlook

The job outlook for welders remains robust, with employment projected to grow by +2% over the coming decade as aging infrastructure, reshoring of manufacturing, and expansion in energy sectors drive consistent demand. Approximately 47,600 job openings are expected each year, stemming from both new positions and the need to replace a large portion of the current workforce nearing retirement. Industries such as construction, shipbuilding, automotive manufacturing, aerospace, and oil and gas extraction are among the heaviest employers of skilled welders, along with government contractors and fabrication shops of all sizes. The push for domestic production of goods and the ongoing need to maintain pipelines, bridges, and industrial facilities ensure that qualified welders are rarely without opportunities.

Welders who develop specialized skills can expect even stronger career prospects and compensation well above the median wage of $47,010. Certified pipe welders, underwater welders, and those proficient in TIG welding of exotic materials such as titanium and Inconel command premium pay and are actively recruited in states like Texas, Louisiana, Pennsylvania, and the Gulf Coast region where energy infrastructure is dense. The Pacific Northwest and Great Lakes states offer strong demand tied to shipbuilding and heavy manufacturing, while sunbelt states see growing opportunities linked to new construction booms. Welders who pursue certifications through the American Welding Society and cross-train in blueprint reading, robotics, or quality inspection position themselves for supervisory roles and long-term career advancement in a trade where skilled labor continues to outpace supply.
