- 15. As the molten weld puddle solidifies, it forms a joint or connection between two pieces of base material B DB E A D
- 18. TAPPING METHOD
- 19. Procedure 1. Were your PPE, always observe safety.
- 20. Procedure 2. Set-up the welding machine 3. Turn on welding machine and Set power source for 70 to 120 amperes.
- 21. Procedure 4. Lay the plate in the flat position on the welding table. Make sure it is well- grounded. 5. Mount the electrode to the electrode holder by 45 degree
- 22. Procedure 6. Strike the arc, using scratching method. Move the electrode across the base metal at an angle you would like to use to strike.
- 23. 7. When the arc starts, Strike the arc by touching the plate, using tapping method.
- 24. Procedure 8. Built-up a short bead at the edge of workpiece metal to the base metal 9. Chip the slag and brush the beads and inspect if the bead properly built-up
- 25. Procedure 10. Practice this job until you can strike an arc freely, without sticking, and where desired. 11. Turn-off the welding machine.

Scoring Rubrics Weight Completion and Work consideration of the process of striking an arc Execution and Mastery of process of striking an arc Interest and Behavior during the properprocess of striking an arc 40% 40% 20% 5 OUTSTANDING: Completed the process of striking an arcwork with high level of performance / output as seen on the oral demonstration SKILLFUL: Demonstrates precise and skillful execution and mastery of process of striking an arc SOPHISTICATED: Demonstrates full interest and appropriate behavior towards the proper process of striking an arc 4 CREATIVE: Completed the process of striking an arc work with enough level of performance / output as seen on the oral demonstration COMPETENT:Demonstrates competent execution and mastery of process of striking an arc EXPRESSIVE Demonstrates a typical level interest and appropriate behavior towards the proper process of striking an arc 3 ARTFUL: Performs the process of striking an arcwork with satisfactory level but with potential performance / output as seen on oral demonstration PRACTITIONER: Demonstrates general level of execution and mastery of process of striking an arc REALISTIC: Demonstrates a general level of interest and appropriate behavior towards the process of striking an arc 2 FAIR: Performs the process of striking an arc work with limited level of performance / output as seen on the oral demonstration APPRENTICE: Demonstrates limited execution and mastery of proper process of striking an arc IMPROVING:Demonstrates inconsistent level of interest and acceptable behavior process of striking an arc 1 ASSOCIATE: Performs the process of striking an arc with low level performance / output as seen on the oral demonstration NOVICE: Demonstrates very low level of execution and mastery of proper process of striking an arc UNEXPRESSIVE: Demonstrates little or no interest and behaves inapproprirately towards the proper process of striking an arc
- 28. Analysis A. Why is there a need to know the proper process of striking an arc? B. How do you maintain the safety prior to perform proper process of striking an arc?
- 29. Generalization Striking the arc is a basic action throughout the entire welding operation. It will occur each time the welding operation is started. The most basic technique to all arc welding is to start and maintain an arc so that current is forced across the gap between the electrode tip and the base metal.
- 30. Valuing You should develop the skills of starting and maintaining an arc with a proper gap or arc length.
