A weld symbol is a representation of a cross section of a given weld. A welding symbol is a composite containing a weld symbol, reference line, and arrow. Additional information can be included in supplementary symbols, and dimensions.
When a flanged corner joint is specified, the other side of the edge weld symbol is often a groove weld symbol. This indicates that a groove weld is required on the opposite side of the joint to ensure proper joint strength and integrity. The combination of both weld types helps to achieve a robust connection in the assembly.
To find the root opening on a groove weld symbol one must measure the depth of filling for plug & slot weld. Rhianna Berriman

FP on a weld symbol stands for "Fillet weld all around." This means that a fillet weld is required to be made on all sides of the joint where the symbol is placed. The weld size, length, and other specifications should be indicated next to or below the FP symbol on the welding symbol to provide further guidance to the welder. It is important to follow the welding symbol precisely to ensure the weld meets the required specifications and standards.
The welding symbol provides essential information about the weld, including the type of weld (e.g., fillet, groove), the size of the weld, the length of the weld, the welding process to be used, and any specific requirements for the weld, such as the finish or pre-weld treatments. It may also indicate the position of the weld and any additional details regarding the joint preparation. This standardized communication ensures consistency and clarity in welding operations.
When the depth of filling is less than the thickness (less than complete), it is specified inside the plug weld symbol!!!
A weld symbol is the shape drawn on a Print to tell the welder: how to prepare a welding joint, what process can be used to weld (mig, tig, arc, etc) what filler rod to use, how wide and long the weld should be, how to deal with the weld after your done (grind flush, brush clean, or nothing) and a million other things.... Its a tool that design engineers use to communicate what the weld needs to be to meet their design specifications.
The name you mentioned isn't of a person who ever existed.
A weld symbol serves as a standardized communication tool in engineering and fabrication drawings, conveying specific instructions for welding operations. It indicates the type of weld, its size, length, and other relevant details, ensuring that fabricators and welders understand the requirements. This symbol helps maintain consistency and accuracy in the welding process, facilitating proper joint preparation and execution for structural integrity.
The center-to-end dimension of a standard long radius 90-degree elbow (often referred to as a "long radius weld 90") is typically 1.5 times the nominal pipe diameter. For example, if the nominal pipe diameter is 2 inches, the center-to-end dimension would be 3 inches. This measurement is critical for ensuring proper fit and alignment in piping systems.
A TCU4a weld is a Corner Jount (TC), Unlimited Thickness Full Joint Penetration (U), Single Bevel Groove (4), and (a) is the welding process.
