PPT-Chapter 3 Shielded Metal Arc Equipment, Setup, and Operation

Chapter 3 Shielded Metal Arc Equipment Setup and Operation OBJECTIVES After completing this chapter the student should be able to describe the process of shielded metal arc welding SMAW list and define the three units used to measure a welding current. Welding. Welding processes are conveniently divided into two classes: . fusion welding and solid state welding. . . During fusion welding a portion of the base materials to be joined is melted and mixed, often with the addition of a filler metal, forming a solid joint after subsequent solidification. . Shera Casseus. Purpose of Lab. The purpose of the Pigment/Paint lab is to create pigments for painting using transition metal compounds.. . Vocabulary . Pigments. - Used for coloring paints, ink, clothing and food. Pigments gets their color from transition metals.. Arc Measure. Arc Measure = the angle measure . Task 12.1. Visual Aid. http://www.mathopenref.com/arcangle.html. Central Angles & Arc Measures. Minor/Major Arcs. Minor Arcs = arcs that are less than 180°.. http://www.gooddirections.co.uk/mach/Mach%20Precision%20Engineering%20Images/Welding%20Metal%20Fabrication%20Home.jpg. Welding 1 . Ibook. Chapter 1 Introduction to gas welding. 1.1 Welding Processes. A Brief History of Welding. Late 19. th. Century. Scientists/engineers apply advances in electricity to heat and/or join metals (Le Chatelier, Joule, etc.). Early 20. th. Century. Prior to WWI welding was not trusted as a method to join two metals due to crack issues. Joining and Assembly. Joining . - . welding. , . brazing. , . soldering. , and adhesive bonding. These processes form a permanent joint between parts. Assembly - mechanical methods (usually) of fastening parts together. A Brief History of Welding. Late 19. th. Century. Scientists/engineers apply advances in electricity to heat and/or join metals (Le Chatelier, Joule, etc.). Early 20. th. Century.

SLO: . 1.2 describe . the organization of the nervous system according to structure, including:. 1.2.1 naming and locating basic components of the central nervous system, including grey and white matter. The pores can be sealed (closed-cell foam), or they can form an interconnected network (open-cell foam).. The defining characteristic of metal foams is a very high porosity: typically 75-95% of the volume consists of void spaces..
