What is the difference between AWS and ISO?

1. ISO uses a dashed line, whereas AWS doesn’t use any dashed line. 2. The other side weld is represented on dotted line in ISO 2553 while there is no dashed line, hence weld symbol placed above the reference line in AWS welding symbol represents weld on other side.

R: In case of Groove Weld or Butt Joint,this is the dimension for the Root Opening.

  • A: In case of groove Weld,this represents the Included Groove Angle.
  • F: This is where the method of obtaining required contour is indicated.
  • —: The horizontal line between F and A is the place of the contour symbol of the finished weld.

    Joint Design – provides information on the type of joint,dimensions and tolerances.

  • Base Metal – material number,subgroup (if any),thickness range that can be welded and the diameter if using tubular components.
  • Filler Metal – specification of the filler metal,F- and A- numbers.

    • How to read welding symbols?

  • Types of Welds. In the center of the reference line,you will see lines or a geometric shape that indicates what type of weld is required.
