WLD 114 - Fabrication/Welding 3

12 Credit(s)

Comprehensive skills necessary for the fabrication of metal products. This course builds and advances skills previously learned. Instruction and practice is given in calculating material costs, shop fabrication techniques, FCAW-S, gas tungsten arc welding, and SMAW. Safe overhead crane operation is also provided in this course.

Prerequisite: WLD 112  and WLD 113  or WLD 111  and WLD 121  and WLD 122  and WLD 143  and WLD 154  and WLD 242  and WLD 256  or instructor consent.
Learning Outcomes
Upon successful completion of this course the student should be able to:

1. Make bills of material from blueprints.

2. Extend material lists in standard form for quantity totaling.

3. Obtain material price quotes.

4. Prepare final estimates of material and labor for bid or purchase.

5. Initiate standard bidding procedures.

6. Utilize computer software to assist in estimating costs.

Shop Fabrication:

7. Layout, cut, drill/punch, fit, weld and align pipe flanges.

8. Layout, cut, fit, weld and finish various structural steel materials to specified standards.

9. Use various metal working machines to form steel materials to specified standards.

10. Develop jigs and fixtures for the purpose of fitting and welding structural metal products.

11. Plan sequencing and expediting procedures similar to those utilized by industry. 1

2. Perform oxy-fuel cutting and electric arc welding in a manner that demonstrates concern for the safety and welfare of themselves and others and property.

Shielded Metal Arc Welding:

13. Perform oxy-fuel cutting and electric arc welding in a manner that demonstrates concern for the safety and welfare of themselves and others and property.

14. Cut steel to product dimensions using manual, and semi-automatic oxy-fuel cutting torches.

15. Metallic arc weld, using E7018 electrodes, in the four standard welding positions, flat, horizontal, overhead, and vertical, on practice pieces and products.

16. Prepare materials, outline testing procedures, make welds, prepare and test metal coupons in conformance with procedures established by the American Welding Society.

Wire Drive Welding:

17. Make power source adjustments necessary to the effective operation of FCAW-SS, GMAW short arc, and spray transfer modes.

18. Identify the type, cause and solution to weld defects typically associated with wire drive processes.

19. Prepare materials, outline testing procedures, make welds, prepare test specimens, and execute testing consistent with standards established by the American Welding Society.

20. Demonstrate proficiency when welding with FCAW-SS, ferrous and GMAW, to a level equal to, or better than, welders who are industrially experienced in these processes.
