Module 7: Gas Tungsten Arc Welding
In this virtual lecture, Michael will discuss Module 7: Gas Tungsten Arc welding also known as Tig welding. This video corresponds with Module 7 in your textbook. Michael will discuss the safety precautions that go along with the GTAW welding process, machine setup, shielding gas, components, and consumables necessary for GTAW. We will be covering the AWS electrode classification for the nonconsumable tungsten electrode as well as the AWS filler metal classification. Michael will also discuss the operator variables that will help you lay a nice weld bead in the joint by using the correct amperage settings, pre and post flow shielding gas, arc length, work angle, travel angle, and travel speed.
Module 8: Thermal Cutting Processes Powerpoint
In this virtual lecture, Michael will discuss Module 8: Thermal Cutting Processes which will cover Oxygen Gas Cutting, Plasma Arc Cutting, and Air Carbon Arc Cutting. This video corresponds with Module 8 in your textbook. Michael will discuss the safety precautions and capabilities that go along with the various cutting processes as well as machine setup, cylinder handling, torch assembly, and consumables needed for each cutting process.
Module 8: Thermal Cutting Processes Machine Setup/Demonstration
In this video Michael will go through the setup of Oxy Gas Cutting and Plasma Arc Cutting. He will demonstrate the setup, operation, and breakdown of the Oxy Gas Cutting torch. Oxy Gas Cutting equipment is some of the most dangerous equipment found in the shop. We will talk about the step-by-step process as well as the safety precautions needed for operating an Oxy Gas Cutting torch. Michael will also discuss the setup, operation, and breakdown of the Plasma Arc Cutting machine including the torch assembly, amperage settings, work angle, travel angle, and travel speed.
Module 9: Welding Inspection and Testing
In this virtual lecture, Michael will discuss Module 9: Welding Inspection and Testing. This video corresponds with Module 9 in your textbook. Michael will discuss the weld joints, positions, parts of fillet and groove welds and how welds are measured and nondestructive and destructively tested. We will also discuss the cause and effect of weld discontinuities which are also referred to as weld defects. Understanding the weld defects and what causes them, you will understand how to visually inspect the weld and adjust the operator variables, machine settings, work angle, travel angle, and travel speed to produce a high quality weld with no defects.
