Dear Readers,
Wish You a Happy Engineer's Day-2016
During Construction at site, we are very often reading drawings and encountered the interpretation of welding symbol. Now let us discuss about welding symbols and special instructions.
Like other aspects of drafting, there’s a set of symbols for welding to simplify the communication between designer and builder (i.e. the site engineer / welder). This language may seem a little strange at first, so it's best to learn it one symbol at a time. These figures represent the core structure of every drafting specification for a weld to be performed. The welding symbol has an arrow, which points to the location on the drawing where a weld is required.
Welding Symbol having three lines. Out of three lines two is must and one is optional.
1. Reference Line (Required Element)
2. Arrow Line (Required Element)
3. Tail (Optional Element)
Below mentioned sketch shows the lines, for better understanding purpose we indicated in different color.
Arrow Line : One end of arrow line connects to reference line and another end (Arrow side) points to a joint, which clearly identify the proposal of joint or Location or Weld area
Tail : It is a optional line and it is used to indicate the supplementary information to be used for welding or cutting or finishing process. Note that this tail may omitted when reference is not used.
Some of the drawing mentioned N/S or F/S or NS or FS. It means Near Side or Far Side. Near side means, Welding should be done where the arrow is shown. Far side means, Welding should be done another side or Opposite side of the arrow is shown.
Some of the special instruction, Drawing representation and welding symbols are as follows.
All in one like Welding symbol, drawing representation and special instruction, are mentioned in below sketch. Click on picture to enlarge.

Below mentioned sketch shows the lines, for better understanding purpose we indicated in different color.
Reference Line : It is always Horizontal Line, One end connected with Arrow line and another end connected with Tail.
Arrow Line : One end of arrow line connects to reference line and another end (Arrow side) points to a joint, which clearly identify the proposal of joint or Location or Weld area
Tail : It is a optional line and it is used to indicate the supplementary information to be used for welding or cutting or finishing process. Note that this tail may omitted when reference is not used.
