What does this welding symbol mean?

Hi everyone

I have a (distant) client who sends me a plan with the characterization of a weld bead, but I don't understand the full meaning.

Sorry for the image quality.

So I understand that I weld on the periphery (the round at the break), that the outgrowth bead will have to be 7mm, but it's the 12 and its symbol that escapes me. Do you have that in a document?

FYI, it's an application of a tube going through a plate.

Thanks in advance

Hello

A small document is attached.

Kind regards.

I would say, Y-weld around the perimeter and spot welding in the corners. And taken up in reverse.

 

to be checked.

12 = Arc welding under powder flow

7 = other welding processes

welding with a half-tulip shaped weld prep with the top of the bead convex on one side of the plate and corner bead neither concave nor convex on the other side of the plate.

Could it fit with your case?

To clarify, the preparation should be something like this:

The tube is shown on the right, the plate on the left. I understood that the "finishing" cord (red) was 7mm, and that underneath there was a J-shaped chamfer (or other).

It is this part that blocks me, is the yellow chamfer defined by these symbols?

Which country does the plan come from? This could perhaps help identify whether the standard is ISO or not

The plan comes from India. However, I don't know if that's where it was drawn.

@frédéric, yes it would stick, now, this tulip chamfer, it has a shape defined just by this symbol and the 12?

Maybe the height of the heel, or the depth of the J?

Hello everyone,

Personally I would have said convex half-U welding but not logical with a tube going through a plate.

Kind regards

So for the record, if the plan is Indian, think that if the welder is in the middle of his career he already has an eye to burn 

I would translate as "soldered straight with a lot of amperage and a big cord"

 

Well ok you noticed that I know nothing about welding but I saw the Indians working at home.....

Hello

I think Frédéric answered your question well, if you want more information go to the Welder's Portal: http://www.soudeurs.com/site.html.

Good luck.
