As a welder assistant, you support the fabrication of metal pipes and equipment by maintaining tools and ensuring a clean work environment. In this role, you may move and clamp workpieces, tidy up working areas, provide welders with tools as requested, and otherwise perform various tasks to help welders spend more time working and less time getting everything into position. Some welder assistants work in teams for larger products, though you are more likely to spend time working one-on-one with whichever welder needs your help. Welder assistants are also known as welder helpers, and companies may advertise this job under either title.
