WLD 135 Pipe Welding 2
Credit Hours:  3
Effective Term: Fall 2016
SUN#: None
AGEC: None
Credit Breakdown: 2 Lectures, 3 Labs
Times for Credit: 1
Grading Option: A/F Only

Description: This course focuses on SMAW and GMAW pipe welding in the 5G and 6G positions. Students will practice pipe fabrication exercises using various piping system components. GTAW pipe welding techniques and principles will be introduced. Emphasis will be placed on proper use and care of tools and equipment along with worksite safety issues. Special attention to performance standards required on critical pressure piping and cross-country pipeline welding will be stressed. Prerequisites: WLD125.

Prerequisites: WLD 125

Corequisites: None

Recommendations: Students should have completed WLD 125 or have the comparable skill sets to be successful in this course.

Measurable Student Learning Outcomes
1. (Application Level) Explain and demonstrate safe working habits and procedures 100% of the time within a lab setting related to the pipe welding trades.
2. (Application Level) Explain and demonstrate the operation of a DC welding machine a minimum of 100% of the lab time.
3. (Application Level) Explain and demonstrate the operation of a GMAW machine a minimum of 100% of the lab time.
4. (Analysis Level) Recognize and select the proper welding rod or GMAW wire for the alloy of the pipe being welded per the welding procedure used.
5. (Analysis Level) Setup the welding machine with proper polarity, amperage, and wire feed speed to complete welding procedure.
6. (Synthesis Level) Perform welded pipe connections in the 5G and 6G positions with an emphasis on proper techniques to produce x-ray quality welds.
7. (Analysis Level) Examine root pass for 100% penetration.
8. (Evaluation Level) Examine, detect and explain the cause of weld defects: inclusion, porosity, penetration and undercut, under fill and burn through in a given pipe weld. Explain and demonstrate measures to correct weld defects.
9. (Application Level) Explain and demonstrate pipe fabrication skills with attention to detailed measurements, proper joint fit up and close tolerances.
10. (Application Level) Explain and demonstrate proper set up and operation of GTAW machine per pipe welding procedures using DC lift arc settings.
