Thermite welders specialize in high-temperature welding using thermite reactions, often in outdoor or remote environments like railroads and pipelines. Arc welders perform a broader range of welding tasks across various industries, with more diverse work settings. While both require welding certifications, thermite welding is more specialized, focusing on joining large metal components in heavy industry.
