Welding happens wherever metal needs to be joined or repaired. This includes factories, construction sites, auto shops, and shipyards. Welders also work in specialized environments like underwater or in aerospace.

Welding is a fabrication process that joins materials, typically metals or thermoplastics, by using high heat, pressure, or both to fuse them. As the materials cool, they form a strong, continuous bond that is often as strong as, or even stronger than, the original pieces.

Welding is done by professionals like industrial welders, pipefitters, and construction workers. Artists also use welding to create sculptures and metal art. Hobbyists may weld for DIY projects, like car repairs or crafting custom metal pieces.

Welding is a highly skilled trade that requires a combination of technical knowledge, physical aptitude, and important "soft skills." While some basic concepts can be learned relatively quickly, becoming a truly proficient welder takes time, practice, and dedication.

Entry-level welders earn around $35,000 to $46,302 annually, often in general fabrication. Specialized welders with advanced certifications can make over $100,000, and some exceed $200,000, especially in high-risk fields like underwater or pipeline welding. Geographic location and overtime can further boost earnings.
