PPT-THE SCIENCE OF SOLVENT WELDING

Presented by Lou Mihamou Director International Sales WeldOn Adhesives Inc Solvent Welding as Science Welding is a scientific process Solvent welding is a form of welding that uses chemicals rather than heat to produce a bond. 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. . INTRODUCTION.  . Robot Welding . is a process of joining different materials. . The . large bulk of materials that are welded are metals and their alloys although welding is also applied to the joining of other materials such as thermoplastics. History of Welding. Welding was used in the construction of the iron pillar in Delhi India, erected about 310 AD and weighing 5.4 metric tons. . History of welding. Welding, was transformed during the 19th century. In 1802, Russian scientist Vasily Petrov discovered the electric arc and subsequently proposed its possible practical applications, including welding.. SOURCE. www.agednet.com. AE240 Arc Welding Safety. Heat for arc welding is obtained by electricity. Electric current flows from a transformer connected to lines from a power plant. Other sources for electricity for welding are electric motors and gas engines driving special generators. . 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 . Plasma Arc Welding. Solid State Welding . Radiant Energy Welding Process . Radiant Energy Beam focuses an energy beam on the work-piece. The heat is generated only when the energy . beam . strikes the work-piece. Radiant Energy beam includes . nature OF WORK. - Welders. , cutters, . solderers. , and . brazers. held about 337,300 jobs in . 2010. -Welders will either work outdoors or in a confined space to contain sparks.. - They wear safety shoes, goggles, masks with protective lenses, and other equipment to protect from burns and falling objects. . Duties . Welders join or sever metals in beams, girders, vessels, piping and other metal components, make metal parts used in construction and manufacturing plants, and weld parts, tools, machines and equipment.. Covered in Subpart H, but an integral part of welding, cutting and brazing. Compressed gases-hazards. compressed energy. flammable, asphyxiants, oxidizers. Gases are used for cutting, brazing and “shielding” the weld. T-Joint. T-Joint made by Arc welding. T-Joint made by MIG welding. T-Joint oxygen acetylene. Butt Joint. Butt Weld from Arc Welding. Butt welding using. Oxygen . A. cetylene . Butt Welding using . MIG Welding. ASTE 3030. Objectives. Define working drawing, print, orthographic projection, and mechanical drawing. Create a working drawing of your project. Differentiate and use different types of lines used on a drawing.
