Upon completion of this course, the student should have developed the skills necessary to weld 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 on a single v-groove weld butt joint on 2” schedule 80 carbon steel pipe in the 6G position using the gas tungsten arc welding process. The joint must be completed using the “cup walking” method and pass a written test. Prerequisite testing charge is $150.00.
Course Objective: To be able to produce quality single v-groove welds on 2” diameter schedule 80 stainless steel pipe and square groove welds on schedule 10 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 pipe using the gas tungsten arc welding process. The students will develop the necessary skills to produce quality single v-groove welds on 2” diameter schedule 80 stainless steel pipe in the 6G position with purge and produce single pass complete joint penetration welds on schedule 10 stainless steel pipe in the 6G position. The student will also have the opportunity to develop skills in welding dissimilar metals (stainless steel to carbon steel) and learn 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 test on a single v-groove stainless steel pipe joint welded in the 6G position, a visual test on a stainless steel to carbon steel single v-groove pipe joint welded in the 6G position and a visual test on a schedule 10 stainless steel pipe joint welding in the 6G position.
