Unit Code: CFW335

Unit Name: The Fundamental Physics of Welding

Description: The purpose of this unit is to enable the development of knowledge, understanding and required for Welding scientific side which a fabrication or sculptural process that joins materials, usually metals or thermoplastics, by causing fusion, which is distinct from lower temperature metal-joining techniques such as brazing and soldering, which do not melt the base metal. In addition to melting the base metal, a filler material is often added to the joint to form a pool of molten material (the weld pool) that cools to form a joint that can be as strong, or even stronger, than the base material. Pressure may also be used in conjunction with heat, or by itself, to produce a weld Although less common, there are also solid state welding processes such as friction welding or shielded active gas welding in which metal does not melt.

Learning Target Outcomes: On successful completion of this course, the participant should be able to: 1. Explain the principles of acceleration due to gravity 2. Identify the action of forces on engineering material 3. Define the principles of work done by movement of force 4. Identify the principles of the force exerted by a fluid on the base of a container. 5. Explain the basics of friction and the effect of heat on metals 6. Identify the two stages of combustion in neutral flame
