Pipeline welding is challenging because, in addition to substantial training and expertise, a pipeline welder is expected to operate in extremely dangerous settings where one wrong move could endanger his or others' lives. That is also why it is one of the best-paying professions in the welding industry. Moreover, pipeline welders often have to travel to different job sites, as pipelines are often located in remote areas. The amount of travel required varies from job to job, but it is not unusual for pipeline welders to be away from home for several weeks at a time.
