How do you size a bevel weld?
The size of weld will be shown to the left of the groove symbol in parenthesis. If there is no number in parenthesis then the size of the weld should not be less than the groove depth. Welding symbol showing both groove depth and weld size.
What is the meaning of flare bevel weld?
Flare bevel groove weld Commonly used to join a round or curved piece to a flat piece. When a backing bar is used to achieve complete joint penetration, its symbol is placed across the reference line from the basic weld symbol.
How thick should a weld be?

| Base metal thickness (T)a | Minimum size of fillet weldb | |
|---|---|---|
| in | mm | in |
| 1/4 < T < 1/2 | 6 < T < 12 | 3/16 |
| 1/2 < T < 3/4 | 12 < T < 20 | 1/4 |
| ¾ < T | 20 < T | 5/16 |
What is a CJP weld?
The Complete Joint Penetration (CJP) groove weld is a groove weld that extends completely through the thickness of components joined. The primary purpose for the use of the CJP groove welds is to transmit the full load-carrying capacity of the structural components they join.
Which size electrode is not one of the most commonly used?
Which size electrode is not one of the most commonly used? 1/4in. Which electrode is a deep penetrating electrode?
How do I calculate what size weld I need?
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
What is CJP and PJP welding?
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.
What is groove weld size?
Often associated with a groove weld is going to be the weld size. This weld size is the depth of penetration you will be getting when applying the weld. When a weld is applied we should be melting into the root of the part so our weld should be larger in dimension than the preparation of the joint.
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 groove weld?
Square Groove. A weld groove formed by the combination of a butting member having a square edge shape and a planar surface of a companion member.
What is the symbol for Weld?
A basic weld symbol consists of three parts namely; Arrow Line: Arrow indicates the position of the joint. The arrow points to one side of the joint. This is called the ARROW SIDE and the side other than the arrow side is called the OTHER SIDE.
