Upon completion of this course, the student should have developed the skills necessary to weld carbon and stainless steel pipe in the 6G position for refineries, power generation facilities and other piping applications.
Prerequisites: The student must have completed the HIWT Gas Tungsten Arc Welding 2” Pipe course. If this course has not been completed, the following prerequisite tests are required:
Pass a visual and destructive test of a single v-groove weld butt joint on 2” schedule 80 pipe in the 5G position using gas tungsten arc welding process. The joint must be completed using the “cup walking” method, and pass a written test. Prerequisite testing charge is $50.00.
Course Objective: To be able to produce quality single v-groove welds on 2-inch diameter schedule 80 mild steel and stainless steel pipe in the 6G position.
Course Content: This course provides the student with a thorough understanding of the preparation, weldability and methods of welding stainless steel and mild steel pipe using the gas tungsten arc welding process. The students will develop the necessary skills to produce quality single v-groove welds on 2-inch diameter schedule 80 mild steel and stainless steel pipe in the 6G position with purge. The student will also have the opportunity to develop skills in welding dissimilar metals and different methods of applying root passes using the GTAW process.
Testing: To pass this course, the student is required to take one written test. The student must also pass visual and radiographic testing on a 6G mild steel pipe and a 6G stainless steel pipe in the 6G position.
