Course Description

Develops a wide variety of pipe welding skills and fabrication skills, and serves as an introduction into the pipe welding and steam fitting industries. Explores industry requirements and procedures, necessary math and tool skills needed to begin in fields related to welding pipe. Prerequisite MFG 201. Audit available.

Course Outcomes

Upon successful completion of this course, students will be able to:
  1. Identify different types of pipe and their common uses.
  2. Describe and fabricate pipe joints for welding.
  3. Explore different types of welding techniques used in pipe welding.
  4. Identify different positions and their strategies used in pipe welding.
  5. Weld pipe with SMAW.
  6. Weld pipe with GMAW.

Suggested Outcome Assessment Strategies

Outcomes are assessed through a mixture of hands on and written assessments.  Priority is given to hands-on proficiency-based assessment in an environment that rewards demonstration of skill needed for success in industry.

  • Lecture and in-booth coaching and direct instruction.
  • Direct instruction in full class demonstration of skills.
  • Written exams.
  • Student proficiency through demonstration of learned strategies and skills in industry standard environment.
  • Mock AWS Testing procedure (destructive testing) or mock local industry supported on-site testing procedures.
  • Job readiness based on performance.
  • In class lab experiments and testing using the scientific process with written result reporting.

Course Activities and Design

The determination of teaching strategies used in the delivery of outcomes is generally left to the discretion of the instructor. Here are some strategies that you might consider when designing your course: lecture, small group/forum discussion, flipped classroom, dyads, oral presentation, role play, simulation scenarios, group projects, service learning projects, hands-on lab, peer review/workshops, cooperative learning (jigsaw, fishbowl), inquiry based instruction, differentiated instruction (learning centers), graphic organizers, etc.

Course Content

Outcome #1: Identify different types of pipe and their common uses.

  • Describe the difference between ERW and seamless wrought pipe.
  • Demonstrate knowledge of the appropriate applications and difference in applications for ERW and seamless pipe.
  • Understand pipe sizing (NPS) and schedules using ANSI/ASME B36.10M.

Outcome #2: Describe and fabricate pipe joints for welding.

  • Identify and fabricate different common pipe joints including open root and socket fitting joints.
  • Utilize different tacking procedures to prepare pipe welding joints.
  • Understand and demonstrate different joint root prep strategies.
  • Read a WPS and correct prepare a joint for welding.

Outcome #3: Explore different types of welding strategies and beads used in pipe welding.

  • Understand how and when to use uphill and downill welding strategies with SMAW and GMAW.
  • Practice uphill and downhill SMAW and GMAW strategies.
  • Describe different possible pass procedures for welding pipe, e.g. rotated vs. fixed, open vs. closed roots, weave vs. stringer beads.

Outcome #4: Identify different positions and their strategies used in pipe welding.

  • Identify and name commonly welded groove pipe positions.
  • Identify and name commonly welded fillet pipe positions.
  • Define strategies for welding pipe in different positions.
  • Explain why a strategy for welding pipe in a certain procedure is necessary.

Outcome #5: Weld pipe with SMAW.

  • Weld pipe uphill with SMAW.
  • Weld pipe downhill with SMAW.
  • Weld in positions 4F, 5F and 6F.
  • Weld in positions 2G, 5G, 6G.
  • Weld in positions 2G, 5G, 6G open root.
  • Take a mock AWS test in 1 of the above F positions and 2 of the above G positions.

Outcome #6: Weld pipe with GMAW.

  • Weld pipe uphill with SMAW.
  • Weld pipe downhill with SMAW.
  • Weld in positions 4F, 5F and 6F.
  • Weld in positions 2G, 5G, 6G.
  • Weld in positions 2G, 5G, 6G open root.
  • Take a mock AWS test in 1 of the above F positions and 2 of the above G positions.

Suggested Texts and Materials

Resources are available openly on the web, but largely the curriculum adaptation needs to be done based on the instructors existing skill set.  Since there are many ways to teach the content, the “teach what you know, and teach well what you do” is very appropriate for courses like this.

The following books are required:

  • Welding Skills 5th Edition B.J. Moniz
  • Welding Skills Workbook 5th Edition Jonathan F. Gosse
  • Print Reading for Welders 5th Edition Thomas E. Proctor, Jonathan F. Gosse

Department Notes

Safety glasses are required at all times in the manufacturing lab, and are provided for students. Students may also purchase their own safety glasses from a local supplier. Long pants and closed toed shoes are required in the welding lab at all times. Appropriate clothing must be worn to work in the lab (no synthetic materials, ect.). Safety requirements are covered prior to work in the lab.
