Thanks to human language, we humans can reach the pinnacle of development that currently no other creature can contest. The weld symbols below are used in addition to the primary weld symbols as shown above. Note how both weld symbols are included on the symbol. The Z shaped symbol with a line through the center displaying the result of 7 in a mirror.
Arc Welding Hazards The symbols shown below are used throughout this manual to call attention to and identify possible hazards. When you see the symbol, watch out, and follow the related instructions to avoid the hazard. The safety information given below isFile Size: KB. Plug and Slot Weld. Plug and slot welds.

When welds are specified on engineering and fabrication drawings, a cryptic set of symbols is used as a sort of shorthand for describing the type of weld, its size and other processing and finishing information. Here we will introduce you to the common symbols and their meaning. The horizontal line — called the reference line — is the anchor to which all the other welding symbols are tied.
Types of Welds Numerous welds can be applied to the various types of joints Considerations when choosing joint geometry and weld types: accessibility to the joint for welding type of welding process being used suitability to the structural design cost of welding. With thicker materials joint accessibility must be provided for welding to ensure weld soundness and strength. Bevel- and J- groove welds are more difficult to weld than V- or U- groove welds Bevel welds are easier in horizontal. Welds in using J- and U-grooves can be used to minimize weld metal These welds are very useful in thicker sections. Groove Welds J-and double-J-groove welds J-groove are moredifficult to weld because of the one vertical side except in horizontal J-and U- are used when economic factors outweigh the cost of edge preparation. Groove Welds flare-bevel and flare-vgroove welds Flare -bevel and flare-v-groove welds are used in connection with flanged or rounded member.
Before welding begins, the welding inspector may be required to examine the weld joint configuration and fit. A Joint is the junction of members or edges of members that are to be joined or have been joined. Their names imply what the actual configuration looks like when viewed in cross section.
Welding symbols, when properly applied to drawings and, as importantly, when correctly interpreted, offer a potentially convenient way of controlling the welding of a particular joint. The need for consistency in both the application of welding symbols to engineering drawings, and the accurate interpretation by personnel directly involved in manufacturing or construction, led to the development of a standard for these activities.
Resembling some sort of hieroglyphics or old English runes, cryptic welding symbols would confuse any layperson looking at a drawing or blueprint. But no welder could do his job without knowing, at the very least, what the most common and important symbols indicate. Engineering and fabrication drawings feature welding symbols that describe the type of weld, its size and other pertinent information. The need for consistency in welding led to the development of a system for indicating welding requirements. Every welder should be familiar with the symbols, and they need to be to do their job. While memorizing all of the welding symbols in the AWS standard is nearly impossible, most welders become familiar with the ones they need fairly quickly.

Available options are determined by the weld symbol style and the associated drafting standard. The dimension specifying the leg size of a fillet weld is placed to the left of the fillet weld symbol, and on the same side of the reference line.
Without adequate welding symbols or proper interpretation, a weldment may not operate adequately or could fail in the field.
