Intermittent welds or also called skip welds are weld seams with unwelded spaces in between. The following example shows a 1/4 inch fillet weld with a length of 3 placed on the arrow side.īack to menu ↑ Welding symbol for intermittent and staggered welds This symbol requires a 1/4 inch fillet weld with a length of 5 inch. If you would like to further specify the length and the width of a weld seam, you can do it the following way: back to menu ↑ Defining the length and width of a weld seam In the following image you can see an example of what it could look like when you use the weld-all-around symbol.īut in many cases, you don’t just want to weld around completely but define a specific length and width of a weld seam. If the weld symbol is on both, on the top and on the bottom side of the reference line, the weld seam must be placed on both sides.Ī circle around the intersection between the reference line and arrow line symbolizes to weld completely around something.If the weld symbol is on the top side, weld seam has to be placed on the other side.If the weld symbol is on the bottom side, the desired weld seam must be placed on the arrow side.
Overall, there are three different possible positions for a weld symbol in the welding symbol: The side at which the arrow is pointing at is called “ arrow side“. The position of the weld symbol clearly tells the welder where the weld seam should be. In the following image you can see examples of how welding symbols can be arranged, but there are even more combinations possible.īack to menu ↑ Difference between arrow side and other side There are multiple orientations of the arrow possible, however the reference line must be oriented horizontally. If you – for example – would like to create a not further specified T-joint you can define a fillet weld with the following welding symbol: Weld information for the “other side” is placed above the reference line. Weld information for the “arrow side” can be read below the reference line. back to menu ↑ How to draw a welding symbol?Ī welding symbol consists at least of a horizontal reference line, has an arrow line pointing to the joint area and can have a tail with additional information for the welding process.
In the following chart you can see the basic AWS weld symbols, groove symbols and also supplementary weld symbols.įor further reference you can also check the handout on AWS here.
The weld symbol is placed above the reference line of the welding symbol. The weld symbol gives you information of the type of weld and is usually a part of the welding symbol. The welding symbol consists at least of a horizontal reference line, has an arrow line pointing to the joint area and can have a tail with additional information for the welding process. The welding symbol describes the “whole thing”, while the weld symbol can be part of the welding symbol.
