The fillet weld symbol is a right triangle placed on the reference line with the perpendicular leg always on the left. The dimension specifying the leg size of a fillet weld is placed to the left of the fillet weld symbol, and on the same side of the reference line.
How do you read a fillet weld symbol?
- Below we see an example of a fillet weld symbol. Fillet weld symbols will ALWAYS have the vertical line of the symbol on the left. The length of the fillet weld, if it is not the entire length of the join, is displayed to right side of the symbol. Intermittent welds are called out using Length and Pitch.

How do you label welds?
The weld symbol distinguishes between the two sides of a joint by using the arrow and the spaces above and below the reference line. The side of the joint to which the arrow points is known (rather prosaically) as the arrow side, and its weld is made according to the instructions given below the reference line.
How do you indicate a weld on a drawing?
Any symbol that is used to show a joint or weld type feature on the other side of the arrow line is always placed on a dotted line. BS 499 and AWS require symbols to be placed above the reference line (which indicate the other side) or below the reference line (indicating the arrow side of the joint).
How do you indicate weld length?
The weld length is the linear distance of each weld segment. The length is shown in the welding symbol to the right of the weld symbol. The pitch is the center-to-center distance of each of the weld segments. It is shown to the right of the length on the welding symbol, with a dash between the two.
What are the 3 main components of a weld symbol?
The basic fillet weld symbol consists of a reference line, an arrow line, the tail, Weld Procedure Specification (WPS) information, and the fillet weld symbol including leg size. Some of the more common optional elements of a fillet weld symbol are shown in Figure 3.
What does G mean in welding symbol?
When a finish symbol is used, it shows the method of finish, not the degree of finish; for example, a C is used to indicate finish by chipping, an M means machining, and a G indicates grinding. When this symbol is placed on a welding symbol, welds are to continue all around the joint.
What are the 3 types of fillet joints?
Tee Joint, Lap Joint, and Corner Joint.
What is the symbol for a plug weld?
Plug welds are a round weld that is made inside of an existing hole most commonly in one piece of metal, welding that piece to another member. The plug weld symbol is a rectangle with a diameter symbol placed to the left of the symbol as well as the number associated with that diameter.
Where is fillet weld used?
The weld is triangular in shape and may have a concave, flat or convex surface depending on the welder’s technique. Welders use fillet welds when connecting flanges to pipes and welding cross sections of infrastructure, and when bolts are not strong enough and will wear off easily.
What are the basic weld symbols?
The skeleton of a welding symbol has an arrow, a leader line (attached to the arrow), a horizontal reference line, a tail, and a weld symbol (not to be confused with welding symbol, which refers to the whole thing. See symbol 1). Hold on, if you’re already lost, don’t panic. It’ll all start making sense soon.
What dimensions can be given for a plug weld?
Dimensions that may be applied to the plug weld symbol include size, depth of filling, included angle of countersink, number of welds and their spacing (pitch).
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.
How many different positions are there for welding plate?
The American Welding Society identifies four primary welding positions: Flat position. Horizontal position. Vertical position.
What is pitch of weld?
The pitch is the distance between centers of segments on one side of the joint. Intermittent fillet welds can be specified on both sides of a joint by placing a fillet weld symbol both below and above the reference line.
Which weld size is considered light?
A light-duty gun is typically considered one that provides from 100 to 300 amps of welding capacity. Like all guns, light-duty ones are rated according to their duty cycle, or the number of minutes in a 10-minute period that the gun can be operated at its full capacity without overheating.
