PPT-Welding Sheet Metal

Flexible Manufacturing Copyright Texas Education Agency 2013 All rights reserved 1 Sheet Metal There are many types of sheet metals manufactured for various applications The sheet metal may be developed to bend stretch or to resist corrosion . 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. . 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. Welding Metallurgy. Study of Welding Metallurgy is important because the overall-mechanical properties of a . weldments . are . determined . by the properties of individual microstructure present in the weld deposit and the weld heat .

Understand and follow all warning labels found on equipment and with all consumables.. Explosion welding (EXW) is a solid-state welding process in which rapid coalescence of two metallic surfaces is caused by the energy of a detonated explosive. .. It is commonly used to bond two . dissimilar metals. . CONTENTS:. . Introduction. Definitions.
