Etymology
Origin of welder
First recorded in 1805–15; weld 1 ( def. ) + -er 1 ( def. )
Explanation
Someone or something whose job involves fusing two pieces of metal together is a welder. If you dream of wielding a blowtorch as you help build a ship, car, or skyscraper, you might enjoy being a welder. A welder's work or hobby is welding — joining one piece of metal to another using heat or pressure, or both. Most welders use a blowtorch that sends showers of sparks into the air as it reaches temperatures of 4,000 degrees or higher. Welders dress in protective gear, including heat-resistant helmets with a darkened lens, safety glasses or goggles, and flame-resistant clothing. A welder is also what we call a machine that is used for welding. The word welder is from weld, which was altered from well, "to boil or rise."
