What is the symbol for weld all around?

In the case of a circular joint, the weld all around symbol is not required. The weld all around symbol consists of a circle that is placed over the intersection where the end of the reference line meets the arrow. Examples of weld all around welds and welding symbols are shown in Figures 10-3 and 10-4.

What is the meaning of the welding symbol shown?

Welding symbols are used to communicate between the designer and the welder. The arrow and leader line point to the joint in question, while the weld symbol tells you what type of weld to do. If the weld symbol is below the reference line (such as in symbol 1), the weld should be made on the same side as the arrow.

Where are welding symbols used?

Weld symbols are used to indicate the welding processes used in metal joining operations, whether the weld is localized or “all around”, whether it is a shop or field weld, and the contour of welds.

What does the weld all around symbol mean?

The weld-all-around symbol indicates that the weld continues completely around the perimeter of the joint. As a reference, take a look at Figure 8 of AWS A2.4:2012, Standard Symbols for Welding, Brazing, and Nondestructive Examinations. Now, circumferential joints, such as those formed by a pipe or rod, are excluded from this requirement.

What does the welding symbol mean on a pipe?

Here is what the symbol is saying: This job is to be done in the field. Bevel the pipe 30 degrees. Weld all around it using a bevel groove weld. Do a .5 inch fillet weld and weld it all around. Complete it by grinding the weld down so that the welds contour is flush.

Where are the welding symbols on a blueprint?

Lets jump into the actual welding symbols found in todays blueprints. The flat reference line has an arrow pointing to the joint that needs to be welded. If the weld symbol is below the line, you must weld the side of the joint being pointed at. Additionally, if the weld symbol is above the line, the opposite side of the joint must be welded.

What does it mean to make a weld without a flag?

The structure of the welding symbol. A weld symbol without a flag indicates that the weld is to be made in the shop. In older drawings, a field weld may be denoted by a filled black circle at the junction between the arrow and the reference line.
