Course Description

TIG Welding and Safety

In this class the students will be introduced to TIG welding and safety procedures. This class will include learning to strike an arc and run beads in flat vertical and overhead positions. They will also learn how to safely set up the tig torch and the proper procedures for grinding their tungsten. They will learn the proper polarity and current settings to weld metal in each position using various joints they have prepared themselves. They will learn the importance of good penetration of the weld joint, how to properly manipulate the weld pool. They will also learn how to properly position themselves and the weld material.

Assessment methods: The instructor will visually inspect welders during the training course and will work with each student individually during each welding session to help them improve their welding techniques. Demonstration of proper techniques will be given to each student.

Course Length

Day One - Introduction of instructor. Safety presentation, knowledge of welding, effects of current, filler rod types, and arc length. Basic welding in flat metal using 3/32” 316L filler rods. Students will learn to properly set up tig torch and will cut all of their practice specimens themselves. After instructor approval students will learn how to set up a “open root” joint and practice the joint in the flat position.

Day Two - Discussion of filler rod manipulation, positioning of the welder and plate. Finalizing of 316 L in flat and vertical position.

Day Three - Discussion of material covered and any problems or questions from students. Begin welding with 3/32” 316L rods in the flat and vertical position.

Day Four - Students will take an open root welding test in plate or pipe.

Materials, Resources

Company will provide:

• Safety equipment; safety glasses, welding helmets, welding gloves, ear plugs and any other required PPE for welding at company’s facility.
• DC welding machines (one for each student) with tig torch attached and equipped with 3/32” tungsten and various cup sizes.
• 4” grinders to clean and bevel welding material, wire hand brushes, course files.
• 4 - 4” x ¼” x 20’ stainless steel flat bar. This will be cut into 7” sections by students for practice sections.
• 1- 20 ‘piece of stainless steel pipe of the most common size used at the plant.
• 2 – 4” x 3/8” x 20’ Stainless Steel flat bar to be used for testing.
• 1 – ¼” x 1.5” x 20’ Stainless Steel flat bar to be used for test backing strip.
• 316 L x 3/32” diameter filler rods rods.
• Welding Machines for each participant and welding area for training.
• Individual welding area should be sectioned off by welding curtains and have a minimum of 2’x2’ steel table top approximately 36” high for welding. (steel grating makes an ideal top for welding and cutting) Each table will need to have a bar or rod that the students will attach vertically to the table for overhead practice. (rod should be long enough to allow attachment of practice piece slightly above head height)
• Each welding station should have a five-gallon bucket of water for cooling purposes.

Maximum class size

8 students (If 10 welding stations are available, we can accommodate 10 students.)
