Jobs for a welder with no experience typically include working as a welding assistant or as an apprentice to an experienced welder journeyman. Your specific duties and responsibilities depend on the type of work you do. If you work at a construction site, you may help welders prepare rebar and other structural materials. If you work in manufacturing, you assist welders and solderers in assembling different components. No experience welders also assist pipefitters who weld together piping, such as oil and gas pipelines, heating ducts, and plumbing pipes for large industrial projects.
