Module 12A: Advanced Oxy-Acetylene Welding Projects (Core)

Module 12A: Advanced Oxy-Acetylene Welding Projects (Core)

Suggested time: 25-30 hours Level: Advanced

Foundational Objectives

To develop effective use of tools and equipment in order to develop entry level skills in the welding trade.
To learn to develop critical evaluation skills in order to judge quality welding workmanship.

Common Essential Learnings Foundational Objectives

To use numeracy skills to estimate, measure, compute, and interpret numerical data in welding. (NUM)
To understand the use of welding technology, its application in the world around us from mining to underwater welding, and its use in space. (TL)

Note: Other CELs may be emphasized.

Learning Objectives	Notes
12.1 To construct a project or projects. (TL)	Projects should be approved by the teacher. Suggested projects: tool box tray (10 hrs.) and box (15 hrs.). The MIG process for tack welding should be used before completing the required welds with oxy-acetylene. Students should have completed MIG theory and practiced MIG equipment use before completing these projects.
12.2 To use technical language and symbols when discussing projects. (COM) 12.3 To develop organized work practices and skills. (NUM) 12.4 To present the project(s).	Planning and management: generate different project ideas, plan and use drawings, determine procedure sequence, prepare a material list and cost estimate, and create a timeline. (PSVS) Fabrication techniques: cut material and set up in the proper sequence and complete each part as required. (CCT) Use a check list to determine that the student: interprets and follows directions, adheres to timelines, works cooperatively, follows safety conditions and procedures, follows all handling and storing procedures, and fulfills cleanup and tool maintenance responsibilities. (PSVS) Students should present the completed project/s and understand the evaluation of the unit.
12.5 To discuss real world applications of welding.	Correlate this objective with the projects and the Careers Module. Reinforce career development throughout the curriculum.

Module 12B: Advanced Oxy-Acetylene Welding Projects (Optional)

Review or repeat Module 12A as required before progressing to the next module at the B30 level.

Suggested time: 25-30 hours

Module 13: Plasma Arc Cutting (Core)

Suggested time: 2-4 hours Level: Intermediate

Foundational Objectives

To develop knowledge of the care and maintenance of welding tools and equipment.

Common Essential Learnings Foundational Objectives

To use numeracy skills to measure and calculate required sizes and shapes of products used and constructed in the welding. (NUM)

Learning Objectives

Notes

13.1 To be knowledgeable about the use and maintenance of plasma arc equipment.

13.2 To correctly use plasma arc cutting equipment to perform various cuts of metal of varying thickness and type. (NUM)

Topics include equipment, safety, gun parts and consumables, cutting of ferrous and non-ferrous metals, and thickness capabilities. (TL)

Students will set pressures, set up materials, start the arc, control the gun and speed, and recognize a quality cut. (TL)

Cut gauge steel.

Cut 6mm (1/4") steel.

Cut test coupons for electric arc, MIG, and oxy-acetylene assignments and projects.

Note: Autobody students are required to cut 16, 20, and 22 gauge metal.
