Drafting Welding Standards

[Rami_T]

What dictates the style of welding symbols used on a drawing? Consider both AWS A2.4, and ISO 2553; do you use the standard associated with the type of title block being used. In other words if you are drawing on a ISO title block do you automatically use the ISO 2553 for the welding symbols? Or do you go with the notes on the drawing, in other words if you say "All welding to be in accordance with ..... AWS D1.1 Latest revision" than we use the AWS A2.4 symbology regardless of the title block being used?

Rami_T,

Use whatever standard your title block claims you are using.

My second pass at this would be that you should call up and use whatever the Machinery's Handbook says. Write a note stating that your weld symbols are to be interpreted as per whatever standard the Handbook call up. You appear to be in Virginia USA. Your welding shop almost certainly has a Machinery's Handbook.

The audiences of the drawing.

Where is the welding happening? What symbols are they used to seeing?

@Rami T:

2014 version of ISO 2553 allows for "System B" - that is using ANSI-style symbology.

So use symbols you are accustomed to.
