Unit of competency
Modification History
Release 1. Supersedes and is equivalent to MSATCS302A Detail bolts and welds for structural steelwork connections.
Application
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.
Pre-requisite Unit
MEM09223 Interpret design specifications for structural steel detailing
MEM09229 Read and interpret technical engineering drawings
Competency Field
Drawing, drafting and design

3.3 Detail bolt and bolt holes taking into account AS 4100 Steel structures requirements, tightening and tensioning specifications and clearances
3.4 Prepare and check field bolt list and send to fabricator
|
|
4. Detail welds for connections
|
4.1 Identify shop and field welds
4.2 Use standard welding symbols
4.3 Apply clearances for welding
4.4 Place field weld details on erection plans and shop drawings and submit to design engineer for approval
|

Performance Evidence
Evidence required to demonstrate competence in this unit must be relevant to and satisfy the requirements of the elements and performance criteria and include:
- following work instructions, standard operating procedures (SOPs) and safe work practices
- complying with requirements prescribed by legislation, awards, agreements and conditions of employment
- assessing design information for adequacy of information needed for structural steel detailing
- liaising with design engineers
- assessing scope of structural steel detailing tasks and priorities
- interpreting design drawings, sketches and schedules
- determining bolt and thread lengths
- detailing bolts to Australian Standard (AS) 1100.101 Technical drawing - General principles, on at least two occasions
- detailing welds consistent with design information, AS 4100 Steel structures, AS 1101.3 Graphical symbols for general engineering - Welding and non-destructive examination, on at least two occasions
- communicating at all levels about technical issues related to patterns and specifications.
Note: Where a volume and/or frequency is not specified, demonstration must be provided at least once.
Knowledge Evidence
Evidence required to demonstrate the required knowledge for this unit must be relevant to and satisfy the requirements of the elements and performance criteria and include knowledge of:
- safe work practices and procedures
- architectural and engineering design drawings including standard symbols, terms, abbreviations and sketches
- structural steel members and connections used in structural steel construction
- difference between design and detail drawing processes
- drawing office procedures
- fabrication processes and procedures
- Australian steel structures limit state design code's (AS 4100 Steel structures) requirements and impact on steel detailing
- Australian standard bolting category identification system
- bolt and thread length considerations including:
- shank lengths as defined in:
- AS 1111.1 ISO metric hexagon bolts and screws - Product grade C, Part 1: Bolts
- AS 1111.2 ISO metric hexagon bolts and screws - Product grade C, Part 2: Screws
