The weld-all-around symbol indicates that the weld continues completely around the perimeter of the joint. It simply means that you have to go around the entire joint. Name Finish Weld Symbol on Symbol base platform weld.

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. As a reference take a look at Figure 8 of AWS A242012 Standard Symbols for Welding Brazing and Nondestructive Examinations. I would argue the welding symbol isnt correct because you cant weld all around the clipped corners.

Now circumferential joints such as those formed by a pipe or rod are excluded from this requirement. Name Weld between points Weld on. Fillet and groove welding symbols Arrow connects welding symbol reference line to one side of the joint Joint illustrated as a single line Arrow of a symbol is directed to the line Arrow side of joint is the near side of the joint Plug slot spot seam resistance flash upset or projection symbols.

Name Fillet Resistance Spot Resistance Steam. Welds that cannot be made in the shop are identified as field welds. Weld entirely around This symbol circles the corner of the base platform to show that the section being pointed at needs welding the whole way around it like a circle.

Flag symbol Field weldMade on site. Contour These symbols designate the final weld end product contour. When this symbol is placed on a welding symbol welds are to continue all around the joint.

Weld all around It signals that the weld is to be made over the entire circumference. Depending upon exact design and stesses that could add or remove stress risers at the plate ends. In engineering drawings each weld is conventionally identified by an arrow which points to the joint to be welded.

The weld all around symbol indicates that you have to keep welding the joint all the way around. Lets say you are welding a piece of pipe onto a plate the weld will generally need to be run around the entire pipe to ensure proper fusion to the plate.

The all around symbol means you are also getting the two short welds at the ends. Its simply a circle. No flag symbol means it will be welded in the shop.

In this case the fillet weld symbol can be above or. Weld All Around Field Weld Symbols. Resistance Spot and Resistance Seam Welds.
