Description
This unit of competency defines the skills and knowledge required to detail various types of bolts and welds for structural steelwork connections consistent with design specifications for residential, commercial, industrial or mining fabrication and construction projects. It is suitable primarily for those working within a drafting work environment with engineering and manufacturing applications.Work may be performed individually on a contracting/project basis or as part of a project team in response to combinations of paper-based and digital instructions.No licensing, legislative or certification requirements apply to this unit at the time of publication.
Notes
Elements and Performance Criteria
1. Determine job requirements
  • 1.1 Follow standard operating procedures (SOPs)
  • 1.2 Comply with work health and safety (WHS) requirements at all times
  • 1.3 Identify job requirements from specifications
