Arc welding is a process for joining pieces of metal. In this process, the high temperature produced by an electric arc near the surface of the metal causes the metal in the pieces to be joined to melt, and upon cooling, to fuse together. This course discusses the most common types of arc welding including shielded metal arc welding, gas metal arc welding, and gas tungsten arc welding. This course also illustrates each type and describes the variables and equipment used in each type.

Learning Objectives

At the end of this course, you will be able to:

• Describe the basic components of the arc welding process
• List the three major types of arc welding
• Describe why shielding is important to arc welding
• Describe the electrode in shielded metal arc welding
• Describe the effect of polarity in shielded metal arc welding
• Describe the electrode in gas metal arc welding
• List what gases can be used in gas metal arc welding
• Describe the electrode in gas tungsten arc welding
• Describe the purpose of a high frequency unit in gas tungsten arc welding

Hot metal welding and cutting has been around for a long time, however, up until recently the applications were limited because generally the parts requiring welding had to be heated in a stationary fire or furnace. This course will briefly cover four of the major heat-based techniques for cutting or removing metal. This will include the principles and equipment used oxyacetylene cutting, air carbon arc cutting, plasma cutting, and laser cutting.

Learning Objectives

At the end of this course, you will be able to:

• Describe the principles of oxyacetylene cutting
• Identify the equipment used for oxyacetylene cutting
• Describe the principles of air carbon arc cutting
• Identify the equipment used for air carbon arc cutting
• Describe the principles of plasma cutting
• Describe the torch used for plasma cutting
• Describe a cutting laser
• Identify different types of laser cutting
• Describe major safety hazards associated with hot metal cutting

Oxyacetylene welding, also known as gas welding, is a process which relies on the combustion of oxygen and acetylene to produce a very hot flame. When these gases are mixed together in the correct proportions, a flame is produced with a temperature that is sufficient to melt steel. This course will cover the basics of oxyacetylene welding and some best practices that should be followed in order to be safe on the job. We will go over how oxygen and acetylene are used in gas welding, the equipment that makes up a gas welding rig, and the PPE required to maintain a safe welding environment.

Learning Objectives

At the end of this course, you will be able to:

• Describe the equipment which makes up a gas welding rig
• Describe why pure oxygen is used in gas welding
• Describe why acetylene is used in gas welding
• Describe what is unique about acetylene storage
• Describe the role of pressure regulators in welding
• Describe the difference between a backfire and a flashback
• List some factors leading to a safe welding environment
• List guidelines for safe compressed gas cylinder handling
• List the PPE required to safely perform gas welding
