Welding Symbol.. Intermittent weld..

Would you happen to know if the way the two triangles are placed on the reference line is important, telling by wich side (arrow or other side) to start the intermittence on?

Example:

On the left you would start the intermittence on the other side, then on the arrow side, etc..

On the right you would start the intermittence on the arrow side, then on the other side, etc..

Example of it matching:

The weld starts on the arrow side, as in the symbol..

:confused:

Thanks :)

I don't believe the orientation of the fillet symbol, i.e., the offset, has any relevance to which side of the joint the initial weld segment is deposited.

The intermittent fillet welding symbol is not intended to be used where precise location of weld segments is required. Instead, the normal way of interpreting the intent of the symbol is:

The minimum length of any segment is as indicated by the symbol.
The maximum unwelded space between adjacent weld segments (on one side) is equal to the pitch minus the weld length.

The initial weld segment does not have to be at the very end of the joint unless you have an in-house requirement to do so.

My comments are based on an interpretation I received from the committee responsible for welding symbols a few years back.

I hope this helps.

Thank you very much,
my teacher wasn't sure, so this would confirm it.
