Introduction
Welcome, future Plate and Pipe Welders! To earn your National Certificate II (NC II), you must prove you can do more than just strike an arc. You must be a master of safety, blueprints, and precision. In this WebQuest, you will step into the shoes of a candidate for a TESDA National Assessment. Your goal is to prepare a Pre-Welding Inspection Report that meets industry standards for carbon steel plates.
Task
Your primary task is to develop a Technical Welding Plan for a "Single V-Groove Butt Joint" in the 3G (Vertical) and 4G (Overhead) positions. This is a critical requirement for the unit "Weld Carbon Steel Plates and Pipes using SMAW." You must produce:
-
A Safety & Tools Checklist: Based on the common competency "Apply Safety Practices."
-
Joint Preparation Specs: Including root gap, root face, and bevel angle.
-
A Weld Defect Guide: Explaining how to identify and repair "Undercuts" and "Slag Inclusions" (aligned to the unit "Repair Welds").
Process
-
Step 1: The Drawing Board (Interpret Drawings and Sketches). Use the AWS (American Welding Society) standards to draw your joint.
-
Resource: TESDA SMAW NC II Training Regulations (See Section 2 for Competency Standards).
-
-
Step 2: Equipment Setup. Research how to correctly set up the welding machine (Amperage and Polarity) for E6011 (root) and E7018 (fill/cap) electrodes.
-
Step 3: Quality Control (Contribute to Quality System). Identify the "Visual Inspection" criteria used by TESDA Assessors. What makes a weld "Pass" or "Fail"?
-
Resource: Lincoln Electric Welding Guides (Search for "Weld Defects").
-
Evaluation
| Performance Criteria | Exemplary (NC II Ready) | Developing (Needs Practice) |
| Safety Compliance | Zero safety violations; all PPE correctly identified for SMAW. | Some PPE missed; general safety only. |
| Material Prep | Beveling and root gap meet exact AWS D1.1 standards. | Incorrect gap or bevel angle. |
| Defect Detection | Can accurately identify 5+ defects and their root causes. | Can only identify 2 defects; causes unclear. |
| Blueprints | Symbols used match TESDA "Interpret Drawings" unit. | Drawing is clear but lacks correct symbols. |
Conclusion
Congratulations! By completing this technical plan, you have mastered the theoretical requirements of the SMAW NC II Common and Core Competencies. In the welding shop, these plans save time, save money, and—most importantly—save lives.
