Welding Symbols

1st: continuous fillet weld (all around? seems like it...), 2nd: continuous bevel butt weld, all around

both: minimum distance from the surface of the part to the bottom of the penetration= 10, to be executed as per given standard

All features are already covered by Pontifex

However you must get yourself familiarised with the symbols in case you are in the business.

The following links are just guidelines, but you should study more on the aspect that too since the above two symbols were one of the most common ones.

Also remember there are a bit of difefrence between ISO and AWS representations (the AWS if I am not wrong shows the welding details above line as the welding on other side where as for ISO it is on this side ) _{but about this I am not very sure confirm this aspect}.

Sir,

I saw the pdf file but i cant understand what is the difference between V groove and

bevel groove type.Can you explain with images

I am giving you some links, However it is advisable to go through some welding technology books. learning here a subject like welding will be only superficial.

Please note again all this do not cover even 1% of the welding I know and may be 0.001% of welding knowledge.

Questions:

#1 - Under what standard are these weld symbols captured? It should be specified on the drawing or in the document from which these weld symbols come from.

#2 - Does the drawing or document list any specific weld symbology or references other than the standard?

#3 - Does the view that the 2nd symbol is pointing at show a bevel preparation?

#4 - Do you have a copy of ISO 5817?

Top is a symbol for a fillet weld the bottom is a symbol for a single bevel groove weld. the circle stands for all the way around the joint. the C ISO 5817 is a special designation probably referring to a certain welding specification or type of electrode. I am not totally sure but the bold line on the bottom stands for a backing strap. The 10 and S10 are not familiar to me if I could see the rest of the drawing or had more info about the piece I could probably figure it out.

it is (ISO 5817) not C ISO 5817 rather EN ISO 5817

and ISO 5817 is Fusion-welded joints in steel, nickel, titanium and their alloys (beam welding excluded) — Quality levels for imperfections"

It ahould have the acceptance levels associated with it too.

S is for deep penetration welds and S10 is the depth of penetration (not the preparation)

It is common in butt welds to proceed a partial weld i.e. not to complete the whole groove (it is not a mandatory to proceed a full penetration for a groove weld, which depends on your calculations), and in this case the size or strength for certain welds must be indicated on the welding symbol, SE.

Where, S means depth of bevel, size or strength for certain weld, and E means groove weld size.

I never Work with ISO 5817 Symbols, I alway Work with AWS Symbols, could you please tell me what mean this one

Que significa a7 y luego simbolo de fillet y luego del simbolo de fillet 50(100) que significa esto
