How do you measure a bevel flare weld?
Measurement of a Flare Bevel or Flare Groove Weld require expertise inspection skills. Usually, measurements is done using the leg length of the flare groove. based on the joint geometry, a minimum leg length shall be specified.
What is flare bevel weld?
Flare bevel groove weld Commonly used to join a round or curved piece to a flat piece. As with the flare-V, the depth of the groove formed by the two curved surfaces and the intended depth of the weld itself are given to the left of the symbol, with the weld depth shown in parentheses.
What does CJP mean in welding?
Complete Joint Penetration
The Complete Joint Penetration (CJP) groove weld is a groove weld that extends completely through the thickness of components joined.
What is the difference between CJP and PJP?
Groove welds are considered to be either “complete joint penetration” (CJP) or “partial joint penetration” (PJP). A CJP weld completely fills the gap between the two pieces. PJP welds are used when it is not required to develop the full strength of the connected parts to transfer the load.
How is welding throat thickness calculated?
To calculate the throat size from a given leg size: Throat = Leg / √2. For approximate size use 1.41 for √2 .
What is effective throat thickness?
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.
How do you calculate CJP welding strength?
The strength of CJP groove welds is assumed the same as the base metal and is not checked….
- FnBM = 0.6 Fu – nominal strength of the base metal – AISC 360-16 – J4.
- A B M = A w e 2 A_{BM}=A_{we}\sqrt{2} ABM=Awe2 – cross-sectional area of the base metal.
What does PJP mean in welding?
Partial Joint Penetration
Penetration Groove Welds The Partial Joint Penetration (PJP) groove weld is a groove weld that does not extend completely through the thickness of components joined.
How do you specify a PJP weld?
When a CJP groove weld or a PJP groove weld is used, do not detail specific groove details and do not call out the symbol for a specific weld type (Example: a double-V-groove or square-groove). Instead, point the weld arrow to the joint location and call out CJP or PJP as shown in the following figures.
How do you calculate weld size?
The width of the weld cap, w, is given by W = 2(tan b x t) + g. The area of the excess weld metal is approximated by the formula (W x h)/2.
How do you measure weld size?
Calculate the weld size, s, at each node on the intersecting edge of the terminated part:
- SS or DS groove welds: s = t. w
- SS or DS 45 ° fillet welds: s = sqrt(2) × t. w
How do you choose weld size?
The size of a fillet weld should be calculated by the designer of the welded structure, based on the nature and magnitude of applied loads, on the material and on the design basis.
What is effective throat of Weld?
The effective throat of a fillet weld is a structural way to be able to understand how strong a fillet weld will be. Generally a fillet weld will have equal legs.
What is flare V groove weld?
Bevel Groove Welds. When two pieces of material butt up against each other,there isn’t room for a weld to penetrate sufficiently.
What is flare V Weld?
The flare bevel groove weld, commonly used to join a round or curved piece to a flat piece. As with the flare-V, the depth of the groove formed by the two curved surfaces and the intended depth of the weld itself are given to the left of the symbol, with the weld depth shown in parentheses.
What is square Weld?
square groove weld. [′skwer ¦grüv ‚weld] (metallurgy) A groove weld in which the joint edges are square.
