Employ thermal cutting and welding tools (non-load bearing) in an underwater environment

Formats and tools

Unit Description
Reconstruct the unit from the xml and display it as an HTML page.
Assessment Tool
an assessor resource that builds a framework for writing an assessment tool
Assessment Template
generate a spreadsheet for marking this unit in a classroom environment. Put student names in the top row and check them off as they demonstrate competenece for each of the unit's elements and performance criteria.
Assessment Matrix
a slightly different format than the assessment template. A spreadsheet with unit names, elements and performance criteria in separate columns. Put assessment names in column headings to track which performance criteria each one covers. Good for ensuring that you've covered every one of the performance criteria with your assessment instrument (all assessement tools together).
Wiki Markup
mark up the unit in a wiki markup codes, ready to copy and paste into a wiki page. The output will work in most wikis but is designed to work particularly well as a Wikiversity learning project.
Evidence Guide
create an evidence guide for workplace assessment and RPL applicants
Competency Mapping Template
Unit of Competency Mapping – Information for Teachers/Assessors – Information for Learners. A template for developing assessments for a unit, which will help you to create valid, fair and reliable assessments for the unit, ready to give to trainers and students
Observation Checklist
create an observation checklist for workplace assessment and RPL applicants. This is similar to the evidence guide above, but a little shorter and friendlier on your printer. You will also need to create a seperate Assessor Marking Guide for guidelines on gathering evidence and a list of key points for each activity observed using the unit's range statement, required skills and evidence required (see the unit's html page for details)

Self Assessment Survey
A form for students to assess thier current skill levels against each of the unit's performance criteria. Cut and paste into a web document or print and distribute in hard copy.
Moodle Outcomes
Create a csv file of the unit's performance criteria to import into a moodle course as outcomes, ready to associate with each of your assignments. Here's a quick 'how to' for importing these into moodle 2.x

Reference books for 'Employ thermal cutting and welding tools (non-load bearing) in an underwater environment' on fishpond.com.au. This online store has a huge range of books, pretty reasonable prices, free delivery in Australia *and* they give a small commission to ntisthis.com for every purchase, so go nuts :)

Elements and Performance Criteria



1. Prepare for cutting and welding underwater

1.1 Work task, worksite data and work object (including composition and condition) are determined and analysed to determine the specific requirements for thermal cutting and welding tools.

1.2 Work plan is developed consistent with the dive plan.

1.3 Thermal cutting and welding tools, and protective equipment appropriate to the task are selected, inspected and prepared.

1.4 Electrical generator and associated leads are selected, inspected and prepared.

1.5 Oxy-acetylene gas cylinders and associated hoses are selected, inspected and prepared.

1.6 Thermal cutting and welding tools, the generator, oxy-acetylene gas cylinders, and associated leads and hoses are secured safely to/from the dive site.

1.7 Access obstructions and other hazards are assessed and action is taken to remove/reduce risk.

2. Operate thermal cutting and welding tools underwater

2.1 Thermal cutting and welding tools are secured on self during the dive for ease of accessibility and lack of interference with mobility and dive equipment.

2.2 Safe routes for leads and hoses to the worksite are established.

2.3 Work-safe area is established and location and safety of divers is confirmed prior to commencing work tasks.

2.4 Surface of the work object is prepared for the cut or weld.

2.5 Voltage and amperage of arc-welding equipment is controlled.

2.6 Gas supplies are turned on and ratios of oxygen and acetylene are set and adjusted.

2.7 Pressure of oxy-acetylene torch is controlled.

2.8 Cuts and welds are made ensuring minimal distortion to the object.

2.9 Employment hazards of cutting and welding tools are managed.

2.10Thermal cutting and welding tools are temporarily disconnected and rendered safe to evaluate the work task.

2.11Cuts and welds are inspected and cleaned.

3. Operate the generator

3.1 Pre-start checks are performed and leads are connected.

3.2 Power is developed gradually without surging and generator is stabilised and trimmed to required work output.

3.3 Routine operational checks are conducted and warning signs are diagnosed and addressed.

3.4 Generator is shut down.

3.5 Emergency shut-down drills are conducted..

4. Conclude underwater cutting and welding operations

4.1 Environmental impact arising from use of thermal cutting and welding tools is minimised and waste products are recovered.

4.2 Thermal cutting and welding tools, the generator, gas cylinders and associated leads and hoses, and protective equipment are de-serviced after use.
