Identify different types of welds. 3 Square Butt Joint 4 Square Butt Joint Continued . Used to butt weld light sheet metal. 1/16 to 3/16 thick metal. 5 Beveled Butt Joint A closed weld is a type of joint in which the two pieces that will be joined are touching during the welding process. An open weld is the joint type where the two pieces have a small gap in between them during the welding process. Square butt joints The square groove is a butt welding joint with the two pieces being flat and parallel to each other.Selection of the type of sheet metal joint has an impact on product design, manufacturing cost, assembly process, joint reliability, and performance. The following factors affect the selection of the sheet metal joining process. Required joint type: permanent or temporary joint; Product application; Assembly process; Material type; Sheet thickness7 Corner Joints Used to join to pieces of metal that are approximately right angles to each other. Closed corner joint is used on light sheet metal were strength is not a required at the joint. Half open corner joint is used on heavier metal when welding can only be done on one side. Used when load is not severe.
spot on two pieces of metal (usually sheet metal) for a short period of time. Resistance to the flow of current through the metal at the spot causes heat, which melts the metal and makes a spot weld. Most frequently used to weld metal joints but sometimes used to weld sheet metal to small diameter rods or small flat bars. 19 Soldering
15. Types of welded joints • b) Butt joints: • formed by placing the plates edge to edge and welding them. • Grooves are sometimes cut (for thick plates) on the edges before welding. • According to the shape of the grooves, the butt joints may be of different types, e.g., Square butt joint Single V-butt joint, double V-butt joint Single U-butt joint, double U-butt joint .Workshop notes for sheet metal joints and opertions. - Free download as Powerpoint Presentation (.ppt), PDF File (.pdf), Text File (.txt) or view presentation slides online. Sheet Metal Joints Sheet Metal Operations Lap joint Seam joint Locked seam joint Hem joint Wired edge joint Cup or circular joint Flanged joint Angular joint Cap joint These types of welding joints form when the two metal pieces are placed end to end together in the same plane surface, it is known as butt joint welding. In welding, this is the most common type of joint. Usually, butt joint welding is used for the fabrication of structures, welding pipes, valves, fittings, and others.

Arc Welding – General Knowledge In Arc Welding the source of heat and the source of filler metal are the same: a consumable electrode or stick, that forms an electrically charged gap between its tip and the metal to be welded. Across this gap flows a plasma of vaporized metal at 7232 F to deposit itself on the molten surface of the work. Arc . Butt joint Corner joint Edge joint Lap joint T joint Types of Welded Joints Square Butt Joints • Used to butt weld light sheet metal. • 1/16 to 3/16 thick metal. Beveled Butt Joints • Used to butt weld heavier pieces of metal together. • 3/8 to ½ inch metal can welded using a single V or U joint. • ½ Inch metal and up can be welded .
14. Brazing • A process that uses a metal alloy that melts above 840 oF, but less than the melting point of the base metal. • Brazing relies on capillary action to draw the filler metal into the joint or to keep it in the joint. The capillary effect is a function of the ability of the liquid to wet a particular material.
