This book contains a task inventory, a task analysis of 150 tasks from that inventory, and a tool list for performance-based welding courses in the state of Indiana. The task inventory and tool list reflect 28 job titles found in Indiana. In the first part of the guide, tasks are listed by these domains: carbon-arc, electron beam, G.M.A.W., gas tungsten arc weld, inspection, layout, oxyfuel, sub-arc, and S.M.A.W. Following are five sections of task analysis guides written by five teachers in Indiana secondary or postsecondary vocational schools or colleges. Each guide contains a task statement, task performance cues, task performance procedures, task elements, and lists of tools, references, and work aids. Appendixes to the guide are a tool list and a welding project task list. (KC)
