Welders are part of the backbone of many traditional industries. When metal pieces, pipes and the like need to be joined securely – or taken apart – the call is made for skilled welders to do the job. Welders fabricate or make metal parts used in construction and manufacturing, from small intricate parts to huge offshore oil rigs. They learn to read layouts, blueprints and work orders, and clean and check parts for defects. They work with powerful, specialized equipment and must place a high priority on safety and prevention of accidents. Welders have been important in industry for a long time, and they will continue to be highly valued in the future.
