Job Task Planning and Organizing
  • Welders organize their work and set up work areas properly. They must gather materials and equipment and set up the equipment following established steps. Generally, welders are assigned work by their supervisors who inform them of the priority of tasks. There is frequent resetting of priorities by supervisors. For example, it is common for welders to be called away from one project to work on another. Although approximately 80 percent of welders' work is done independently, they need to coordinate their work with others, including apprentice welders, fitters and other tradespeople. In a plant or shop setting, welders must share equipment, such as cranes, saws and grinders, with co-workers. If equipment is not available when they need it, welders work on alternative tasks. (2)
  • Welders face disruptions of work schedules, timelines and budgets when project designs are found to be faulty and when specifications are changed after projects have already started. (3)

Decision Making

  • Encounter delays due to equipment breakdowns and shortages of materials. Inform supervisors about equipment breakdowns and shortages of materials. Perform other work until repairs are completed and necessary materials arrive. (1)
  • Encounter difficult work conditions due to factors, such as bad weather. Reschedule activities or devise solutions in consultation with clients and supervisors. (2)
