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.

What is girth weld?
circumfrencial weld is sometimes referred to as Girth weld. its just another term.
Can you weld steel to steel?
Yes, you can weld steel to steel. You can use steel welding rod.
Why is it important to strike the arc only on the weld joint?
why is it important only to strike the arc in the weld joint
What is definition of the under run in filet weld?
A fillet weld in any single continuous weldmay underrun the nominal fillet weld size specified by2 mm [1/16 in] without correction, provided that theundersize portion of the weld does not exceed 10% of thelength of the weld. On the web-to-flange welds on girders,underrun shall be prohibited at the ends for a lengthequal to twice the width of the flange.
Is a flare groove weld considered a partial penetration weld?
Without knowing exactly which Code or industry this applies to, I'll give it a shot using AWS D1.1 standards. The standard flare-groove detail is P10 indicating that it is a PJP (partial joint penetration) weld. If a weld size is not indicated, it is assumed it is a full thickness weld and I believe this is where the confusion comes in. It's a partial penetration with full thickness and that's where the argument starts. This weld could be used as a full penetration weld (and held to that testing criteria) but the detailer must be specific about the intentions, particularly if it is used in a critical joint.
What is the difference between a weld symbol and a welding symbol?
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(n) weld symbol.?
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.
Where does the roots opening on a groove weld symbol?
To find the root opening on a groove weld symbol one must measure the depth of filling for plug & slot weld. Rhianna Berriman

What does c p on a weld symbol mean?
The "c p" on a weld symbol indicates "continuous weld." This notation specifies that the weld should be applied continuously along the joint, as opposed to being intermittent or spot-welded. It ensures a consistent and uniform application of the weld material for structural integrity.
What does FP on a weld symbol mean?
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.
What are five things the welding symbol will tell the welder about the weld that is to be made?
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.
What does PP on a weld symbol mean?
PP on a weld symbol stands for "Partial Penetration." It indicates that the weld does not fully penetrate through the thickness of the base materials being joined. This type of weld is often used when complete penetration is not necessary for the structural integrity of the joint or when it is impractical to achieve full penetration.
Is plug weld's depth of filling to the right or left of the welding symbol?
When the depth of filling is less than the thickness (less than complete), it is specified inside the plug weld symbol!!!
What is the purpose of a weld symbol?
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.
How do you read the weld dimension if the symbol a or z not mentioned?
If the weld dimension symbol "a" (length of the weld) or "z" (throat thickness) is not mentioned, you typically refer to the standard weld size specified in the welding procedure or code applicable to the project. The default dimensions may be implied based on the type of joint and the material being welded. Always consult relevant standards or specifications to ensure compliance with the required weld sizes and types. If in doubt, it's advisable to clarify with the design or engineering team.
What does TCU4a weld symbol mean?
A TCU4a weld is a Corner Jount (TC), Unlimited Thickness Full Joint Penetration (U), Single Bevel Groove (4), and (a) is the welding process.
