Introduction Introduction (LSI Quadrant I): SAY: “The joint welding procedure mentioned includes the materials, practices and detailed methods employed in the welding of a particular joint. In the industry of welding, there are many different types of materials joined together. Take a look around the room and let me know how many joints you see. If you could see through the walls, do you think you would see joints welded together? One of the essential types of welding if that done on joints.” You may wish to show various pictures of types of joints welded together. Outline Outline (LSI Quadrant II): Introduction Instructor Notes: The PowerPoint presentation Should be shown after Introduction List the objectives on the board. . Show the PowerPoint. I. Safety Terms i. Bevelii. Chamfer iii. Groove angel iv. Lack of fusion v. Land vi. Stag vii. Weld reinforcement viii. Lameliar tearing II. Weld Positions i. Flat ii. Overhead iii. Vertical iv.

Pass out and explain rubric. V. Preparing to weld i. Preparations ii. Guidelines iii. Safety iv. Set up equipment VI. Students practice joint welding with instructor guidance. VII. Independent practice. This is a sample rubric and the individual instructor may wish to emphasize other skills for higher points. Application Guided Practice (LSI Quadrant III): The teacher will demonstrate safety, set up, and weld. A student may or may not be used to demonstrate if they are advanced. Independent Practice (LSI Quadrant III): 1. Safety setup (students must be checked off on safety) 2. Equipment setup. 3. Students practice weld. Instructor goes around and checks for understanding and safety. Summary Review (LSI Quadrants I and IV): Check for mastery/understanding by orally reviewing the students on the information. Answer any questions the class may have. Ask individual students identify stages of the process. Evaluation Informal Assessment (LSI Quadrant III): Copyright © Texas Education Agency, 2012. All rights reserved. 4 Instructor should monitor student understanding throughout the lesson. If further explanation is needed on a given topic, instructor should elaborate or re-teach that portion of the lesson. Check for general mastery level of each student during review time. Formal Assessment (LSI Quadrant III, IV): Mastery of at least 70% on the rubric. Extension/Enrichment (LSI Quadrant IV): For those students who need remediation, a re-teach and review session will reinforce the topics of concern. The remediation will need to be tailored to the individual needs of the student. Copyright © Texas Education Agency, 2012.
