Module 6: Oxy-Acetylene Cutting (Core)

Suggested time: 5-8 hours Level: Intermediate

Foundational Objectives

To be aware of the potential danger to fellow workers who are engaged in activities in the accompanying work space.
To develop effective use of tools and equipment in order to develop entry level skills in the welding trade.

Common Essential Learnings Foundational Objective

To use numeracy skills to meet the demands of a specific task in welding. (NUM)

Note: Other CELs may be emphasized.

Learning Objectives

Notes

6.1 To demonstrate knowledge of the oxy-acetylene cutting process by recalling the information required in introductory modules.

6.2 To identify precautionary procedures when using the oxy-acetylene cutting process.

6.3 To identify the cutting torch and the function of the parts.

6.4 To describe the relationship between tip size, metal thickness, and gas pressures. (NUM)

6.5 To cut coupons.

6.6 To cut required material using the semi-automatic cutting torch.

See Modules 1 and 2.

Students should demonstrate a knowledge of equipment, safety, set up, protective gear, compressed gas, cutting containers, flammable materials, oxidizing materials, and types of materials that can be cut.

Factors affecting cut quality include metal thickness and metal condition. (TL)

Students may cut materials to be used for an Electric Arc Practical.

Module 7A: Advanced Oxy-Acetylene Cutting (Core)

Suggested time: 3-5 hours Level: Advanced

Foundational Objective

To develop effective use of tools and equipment in order to develop entry level skills in the welding trade.

Common Essential Learnings Foundational Objectives

To use the language, symbols, and terms specific to the welding field and to express knowledge of welding using communication skills. (TL, COM)
To use numeracy skills to measure and calculate required sizes and shapes of products used and constructed in welding. (NUM)

Note: Other CELs may be emphasized.

Learning Objectives

Notes

7.1 To cut straight lines on gauge metal. (TL)

7.2 To cut straight lines on heavy plate. (NUM)

7.3 To bevel cut plate edges for butt welding assignments.

7.4 To cut holes and circles.

Review Modules 1, 3, and 4.

Cut 16 gauge and 6mm (1/4") mild steel. (NUM)

Students should select appropriate cutting tip, evaluate hazards, set correct flame, inspect and clean welds, and evaluate the finished cut. (PSVS, COM)

Refer to SIAST Level I resources for bevel cut plate edges practical assignment(s).
