Structural Steel Profiles and Welding Symbols The purpose of this page is to introduce you to some other symbols and abbreviations that are quite common on engineering drawings. Structural steel profiles are not drawn in most cases, nor are welds drawn or sketched as shown on the next page. These are only a few of the total number of symbol and abbreviations available in each area,
A welding symbol has three parts: Reference line: this is the main part of the symbol and it's function is to carry or provide all the information on the weld to be made. Arrow: this is what is used to point the reference line to where you need to weld. Tail: This is used to provide additional but important data as wells as information needed to complete the weld.
Surface Roughness symbol in drawing Surface roughness symbol is given to convey manufacturing process related information only. Unless written specifically on the symbol, they do not carry the surface texture type (i.e. plated / milled / cold drawn). These symbols are given irrespective of material and its surface condition.

(1) The following welding symbols are used for light gage metal joints involving the flaring or flanging of the edges to be joined (fig. 3-59). These symbols have no arrow or other side significance. (2) Edge flange welds shall be shown by the edge flange weld symbol (A, fig. 3-59).
The symbol's perpendicular line is always drawn on the left side, regardless of the orientation of the weld itself. Common supplementary symbols used with groove welds are the melt-thru and backing bar symbols. Both symbols indicate that complete joint penetration is to be made with a single-sided groove weld. In the case of melt-thru, the root ...
In addition to contour symbols, finish symbols are used to indicate the method to use for forming the contour of the weld. 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.
