CONTENTS Introduction Definitions Soldering Classification of solders Classification of fluxes Heat source in soldering Techniques of soldering. Chapter Overview. This chapter considers three joining processes that are similar to welding in certain respects: . Brazing, Soldering, and Adhesive Bonding. Advantages and Disadvantages of Each Process. 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. "Support . of. . teaching. . technical. . subjects. in . English. “. Tutorial. : . Engineering. technology.

S.R.Norr. , UMD. Definition: Soldering. A process in which two or more items (usually metal) are joined together by melting and putting a filler metal (. solder. ) into the joint, the filler metal having a lower melting point than the adjoining metal. The intent is to create a strong MECHANICAL joint. © 2014 Project Lead The Way, Inc.. Digital Electronics. Soldering & De-soldering. 2. This presentation will….

Remove flammable and combustibles if possible. Ensure that charged flammable gas lines and vessels not within 35’. Use . FM approved . BRAZING. Brazing is a joining process in which a filler metal is melted and distributed by capillary action between the faying surfaces of the metal parts being joined. No melting of the base metals occurs in brazing; only the filler melts. In brazing the filler metal (also called the brazing metal), has a melting temperature (.
