AUTO CAD TOOL IN THE FIELD OF WELDING BY MIND Maryanto, ST

Welding is to connect two pieces of metal by the hot melt material added. Welding is one way to get a connection permanen.Las also widely used in the manufacture of machines or structures that were previously made ​​by casting or forging. Welding is one of the few mechanical process that adds material to the workpiece. Welding symbols on engineering drawings provide clear instructions for welding expert in doing welding. Location of components in the welding shall be clearly identified by means of welding symbols. CAD libraries can simplify the process of drawing. To simplify how the placement of a complete welding information, a system of symbols has been developed by AWS welding (American Welding Society), published in 1947 under the title, "Standard Welding Symbols". This symbol was taken over by the ANSI (American National Standards Institute) and is now published as ANSI / AWS A.1.1 - 1989

Welding symbols picture for the location of elements of the standard welding A special diagram welding is an image pair consisting of a number of components that are combined together as one unit. Welding on the working drawings are not drawn, but it is shown by clear and complete welding symbols. Given the size of the component to provide the amount of information that will be used. Connections as indicated in shape before welding.
