What is 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 a dotted line in ISO 2553 while there is no dashed line, hence weld symbol placed above the reference line in the AWS welding symbol represents the weld on other side.

What does Z and a mean in welding?

z = leg length. s = penetration throat thickness. For butt joints and welds, an S with a number to the left of a symbol refers to the depth of penetration as shown in Fig.

What does GF mean in welding symbol?

GF for GMAW or FCAW. S for SAW. Not any of the above=SMAW. U=Unlimited Thickness, Complete Joint Penetration. L=Limited Thickness, Complete Joint Penetration.

What is CJP weld symbol?

If the engineer intends to require a complete joint penetration (CJP) groove weld, the letters “CJP” are to be shown in the tail of the symbol. This is still a very simple rule, yet it permits some desirable options. It does not permit unconservative welds.

How many weld symbols are required?

The assembled “welding symbol” consists of the following eight elements or any of these elements as necessary: Reference line. Arrow. Basic weld symbols.

What are the 5 supplementary symbols?

What is PJP and CJP?
