What is the effective throat of a groove weld?
Effective throat of a weld is the shortest distance from the joint root to its surface. The effective weld size of a PJP groove weld shall be the depth of bevel with or without a deduction of 3 mm (1/8 in.) (AASHTO/AWS D1.
What is the throat of a bevel weld?
The throat is the shortest distance from the root to the face of the weld. To measure this dimension in a regular mitre or flat faced fillet weld is relatively simple.
What is a flare bevel groove weld?
Flare bevel Groove Weld is type of a weld where a groove is formed between a joint member with a curved surface and another with a planar surface. So, for a flare bevel groove to take place, one joining member need to be a tubular shape.
Is a flare bevel weld a groove weld?
Welders typically employ a flare-bevel-groove weld when joining a round or curved piece to a flat piece.
How do you calculate the effective throat of a weld?
To get the throat size for an equal-leg fillet weld simply multiple the leg size (w) by the cosine of 45˚, which is 0.707. So a 0.330 leg would yield a 0.330 x 0.707 = 0.233” throat. This is why leg sizes are called out for fillet welds.
What is the effective throat thickness of a fillet weld?
Explanation: Effective throat thickness is the shortest distance from the root of fillet weld to face of diagrammatic weld(line joining the toes). The effective throat thickness should not be less than 3mm and it should not exceed 0.7t or 1t, where t is thickness of thinner plate of elements being welded.
What does effective throat mean in welding?
The minimum distance from the fillet weld face, minus any convexity, and the weld root.
What is effective throat?
Effective Throat – The minimum distance minus any reinforcement between the weld root and the face of a fillet weld. Actual Throat – The shortest distance between the weld root and the face of a fillet weld.
What is groove weld used for?
0 Standard Welding Terms and Definitions as “A weld in a weld groove on a workpiece surface, between workpiece edges, between workpiece surfaces, or between workpiece edges and surfaces.” A weld groove is defined as “A channel in the surface of a workpiece or an opening between two joint members providing space to …
How do you calculate effective throat thickness?
The effective throat thickness of a fillet weld is
- equal to the size of the weld.
- a function of the angle between the fusion sides.
- length of the hypotenuse of the triangle formed.
- 0.7 times the size of weld.
What is effective weld length?
Effective length is the length of a continuous full-size weld. Four times the size of weld. Fillet Weld. Effective length is taken as the overall length of the weld minus two times the size of the weld.
How do you calculate the effective throat of a fillet weld?
When the size of weld is 10 mm What is the value of throat thickness?
What is the effective throat thickness dimension of 10mm fillet weld made by shielded metal arc welding and submerged arc welding? effective throat thickness = 0.7a = 0.7×12.4 = 8.6mm.
What is groove weld?
What is single-bevel groove weld?
[′siŋ·gəl ¦bev·əl ′grüv ‚weld] (metallurgy) A groove weld in which one member has a joint edge beveled from one side.
What is the most important factor in a groove weld?
The most important factors include the size and type of weld, edge preparation, metal thickness, reinforcement members and distortion. Each of the above factors can affect and change the process of welding.
What is throat thickness of weld?
The throat of the weld is the distance from the center of the face to the root of the weld. Typically the depth of the throat should be at least as thick as the thickness of metal you are welding.
What is the effective throat thickness dimension?
How is welding throat thickness calculated?
The Throat thickness for the fillet weld formula is defined as the distance through the throat, as distinct from width or height is calculated using Throat thickness = 0.707*Thickness of plate. To calculate Throat thickness for the fillet weld, you need Thickness of plate (t).
What is groove welding and its types?
Groove Weld: Groove weld is defined as an opening between the two joint members which provides the space to contain the metal. Groove welds are the most used welds after the fillet weld. There are seven basic types of groove weld: Square groove weld. Single-V groove weld.
What is flare bevel groove weld?
Flare bevel Groove Weld is type of a weld where a groove is formed between a joint member with a curved surface and another with a planar surface. So, for a flare bevel groove to take place, one joining member need to be a tubular shape. For example, a weld formed between a pipe and plate placed horizontally to each other as shown in below figure.
What is the effective throat of a PJP groove weld?
The effective throat of a PJP groove weld or flare groove weld filled less than flush shall be as shown in Table J2.1 or Table J2.2, less the greatest perpendicular dimension measured from a line flush to the base metal surface to the weld surface.
Is it possible to measure the effective throat of a groove welder?
It can be shown that, ( α R O). This methodology is now formalized in the article “Measuring the Effective Throat of Groove Welds,” which appears in the February 2017 edition of the AWS Welding Journal. Thanks for contributing an answer to Engineering Stack Exchange!
Do I need a fillet for flare-bevel welds?
Occasionally I have to design T-connections between rectangular tube steel (HSS) members where I have a flare-bevel weld between the corner of the tube and the connecting flat member. If the weld stress is high enough, a reinforcing fillet may be required. Per AWS D1.1-2010, Section 22.214.171.124,
