Help with drawings

[John12345]

Could anybody pls help me with these symbols. Does it mean fillet weld one side but confused with the staggered lines, thank you.

The staggered lines mean that the end plate surface is 6mm inside the end of the side rails.

Plenty of stuff on the net - just make sure you get the UK standards.

But I would read that as a 6mm fillet, this side, 8 places - so on the outside of the four tabs poking through the end plate, at each end, nothing on the inside.

just checked - looks like its to standard BSI BS EN ISO 2553:2019, system A. the dashed line is described in table 5, and the example shown is "weld to be on same side as arrow". the x8 in the tail is 8 locations (2 per edge, 4 edges).

So the dashed line is superfluous.....

No - if it was missing it would mean weld both sides.

This is your example: top left.

so you have to make a a6 fillet weld.
and 8 times in the same position.
and now you have to see if what is written on the drawing is correct

That's probably one of the clearest ways of illustrating it that I've seen - where's it from?

I got away for a number of years when I first started with the note "fully weld as required" or "stitch weld as required" on drawings . . . our fabricators were very good - I learnt a lot.

This is from ISO 2553:2019(E).

You have to be careful with the American version AWS A2.4, it is different and has no broken lines.

My copy of standards are from a good while ago - the explanations take a bit of working out.

I've sat in American design offices, so I've had to make a good attempt with their standards too. Everything seemed to go together and stay together, so fingers crossed I got it right 20 odd years ago.

One of the CAD systems I've used tried to assist you in selecting the right symbols, but got the reference/dashed line swapped about.
