What is the symbol for a groove weld?
Like the basic fillet weld symbol, the groove weld symbol consists of a reference line, an arrow line, the tail, Weld Procedure Specification (WPS) information, and the appropriate groove weld symbol. Groove weld symbols can be much more complex than fillet welds symbols.
What is the symbol of a groove weld size?
Determine the weld size. The size of the weld is the effective throat on a groove weld. This includes the depth of groove and the additional penetration into the root. The size of weld will be shown to the left of the groove symbol in parenthesis.
What are the 5 types of groove welds?
There are seven basic types of groove weld:
- Square groove weld.
- Single-V groove weld.
- Single-bevel groove weld.
- Single-U groove weld.
- Single-J groove weld.
- Flare-V weld.
- Flare-bevel weld.
What is the symbol for site weld around?
In the case of a circular joint, the weld all around symbol is not required. The weld all around symbol consists of a circle that is placed over the intersection where the end of the reference line meets the arrow. Examples of weld all around welds and welding symbols are shown in Figures 10-3 and 10-4.
What are welding symbols?
Welding Symbols | Basic and Supplementary Weld Symbols Types & Drawings
- Welding Symbols are a graphical way to convey information about a welding joint.
- Reference Line.
- Arrow.
- NOTE: Both S and E are always placed to the left of the weld symbol on the reference line irrespective of the arrow.
What is the basic weld symbol?
Each welding position has its own basic symbol, which is typically placed near the center of the reference line (and above or below it, depending on which side of the joint it’s on). The symbol is a small drawing that can usually be interpreted as a simplified cross-section of the weld.
What is the symbol for field welding?
A field weld is defined by the American Welding Society (AWS) as “[a] weld made at a location other than a shop or the place of initial construction.”1 The field weld symbol consists of a flag that is placed at the intersection where the end of the reference line meets the arrow (see Figure 10-5).
What do the symbols on groove welds mean?
Common supplementary symbols used with groove welds are the melt-thru and backing bar symbols. Both symbols indicate that complete joint penetration is to be made with a single-sided groove weld. In the case of melt-thru, the root is to be reinforced with weld metal on the back side of the joint.
What is the anatomy of a groove weld?
The anatomy of a typical groove weld is illustrated in Figure 3. Like the basic fillet weld symbol, the groove weld symbol consists of a reference line, an arrow line, the tail, Weld ProcedureSpecification (WPS) information, and the appropriate groove weld symbol. Groove weld symbols can be much more complex than fillet welds symbols.
What does t mean in welding symbols?
The effective throat, T is indicated in parenthesis in the weld symbol. This element is only shown when the weld is not to be full penetration and represents the desired penetration depth of the weld. Just like the fillet weld, the face of a groove weld can be required to be flat, convex, or concave.
What is a V groove in welding?
With V-groove welds, the edges of both pieces are chamfered, either singly or doubly, to create the groove. The weld symbol provides the angle of the V, as well as the separation at the root, if any (Fig. 3).
