The Weld Symbol function can be used to attach information about welding procedures and designs to your component.
Click the Weld Symbol 
so that the Weld Symbol dialog box opens.
The specific weld seam information is entered under Arrow Side and Other Side, but its meaning is relatively complex and not content of the lecture.
Otherwise, the PMI settings and placement work in a similar way to the functions of the previous chapters:
Under Associated Objects you can select one or more surfaces to which your weld seam information should refer. These will turn green when you click on the PMI.
Click on Specify Location to place your PMI. To do this, use the LMB to select any element of your component, hold it down and drag the tolerance frame vertically or horizontally to the position in the graphics window on which you want to place your PMI. The PMI is then placed down by repeatedly clicking the LMB. This should appear automatically in the level of the corresponding view. Otherwise you can select a desired layer under Orientation->Plane. If you have problems with the length of the arrow, you can reduce it under Style->Stub Length. Then confirm with OK.
