bs en 287 /BS EN ISO 9606 6g stick test

[chip]

morning all im a mig welder stuck in a sheet metal shop ive done a lot of heavier prior to this and have kept my hand in stick welding.
I want to go in for some coding in stick...getting a company to pay for this is out of the question so please..im not interested in wether you think I should not be paying for my own codes..its what im doing.
I mentioned the en 287/ and iso9606 6g to a pipe fitter I used to work for( I know the en 287 is to be fazed out) he said if I can get my asme9 he could put a lot of work my way.but my thinking is that would limit me and that the 287/9606 would not only cover me for pipe work but covers structural??
I have read it may be possible to pay a little extra and get dual coding.

Im in Leicester and the nearest place I know of for this coding is a test centre in Coventry.
ive read lots of info on tests ..test prices various codes etc but having never done one of these coding tests my my main questions are regarding the test perimeters.
so say for 6G is the pipe diameter and wall thickness to be determined by me or is there a standard in these tests
if its by me and I get a pass am I limited to working to that size and gauge pipe or material thickness?
with boiler pipe and structural steel in mind thanks.
theres very little info on the Coventry web page regarding the test itself just pricing coding etc.

is it not possible to edit posts

thanks mrfuzzy
some good info there, ive been welding in stick and mig for almost 20 years heavy to light so Im hopeing it wont take me too long to get upto scratch with this 6g before putting in for the test.
so reading in your link it suggests diameter.. code wise would be restricted to what ever pipe you passed on and further testing/coding is needed if you wish to weld larger pipe same goes for grade of steel.
the pipework I would have coming my way would be heating/boiler systems,its the structural steel work..plant etc I really want the code for.but will take the pipe if it comes.
it would be nice to know if anyone else has done this 6g stick and used a test centre.. were you permitted to take your own prepped test material rods etc.im guessing not? thanks

You will be coded for a specific material and specific filler.then its half the pipe diameter to double it.half the thickness i.e. schedule of the pipe to double it
so if you tig weld 6 inch carbon steel sched 80,you will be covered for 3 to 12 inch carbon pipe,schedule 40 to 160.if er70 filler is used then only that is what you will be covered for
you will pay for materials supplied to you,and prep work will be done by you and inspected.

depends on what industry you want to work for.
Oil and gas, petrochemical, as said, is mostly asme

structural is mostly EN 287 /EN ISO 9606

offshore is still different, mostly

see the mostly after each sentence, there are always exceptions.
The best way is to determine first where you want to work, check with them and see what sizes/thicknesses/materials they work with, and get coded according to these needs.

thanks dimitri structural is what im in it for mainly but id also like to do pipe when it arises, I might enquire about duel coding. trying to get my head around the all the info regarding what qualifies you for what pipe diameter wise in carbon steel and not be too limited.

You know your doing the right thing in your circumstances. I think most get the response you anticipated "don't pay for your own" is most who ask have no experience and think you can just pass a test and jump in both feet

 

[Dimitri De Spiegeleer]

for structural, you'll want to be coded according to EN ISO 9606-1.
Pipe can be both, this is mainly determined by the type of company.

see table 6 and 7 (EN ISO 9606-1) below, that's a good way to get started.

thanks kent and dimitri I appreciate your help but the tables are no help. ive no clue what the symbols mean,it really narks me how for years you get told thickness or gauge to be welded in tig mig or arc.the material..and weld specs.everyone understands...to me these weld tests charts and tables are over complicated ,

They are confusing because they are not in any context, don't fret just book assessment and then the required training the assessor thinks applicable then the test. Only take tests for the work that is actually on offer with contacts made though as its a use it or loose it thing

 

[Dimitri De Spiegeleer]

Tables are out of context, indeed, but they show that if you get coded by welding a tube of diameter 50mm and wall thickness 12mm, you're good for everything bigger than 25mm diameter and 3 mm wall thickness. Which is a rather extended validation.

 

[Kent]

They are if your not with the program already! Your average Tinbasher or Fabricator just wont get the meaning of them before they start with the program (out of context for the guy "at this stage" not the subject)

 

[Dimitri De Spiegeleer]

True, didn't really think of that, I tend to go too fast sometimes as I've been doing this for some time now.
Either way, I think the above suggestion is a good place to start, even better would be a 10 minute chat with a welding foreman or course responsible who actually knows his **** and who is willing to show you the 9606-1 standard, and how to interpret the various tables.

 

[Kent]

Better still talk with the likely work supplier contacts then the training provider. Welders weld you see most aint too big on forms, tables and spreadsheets. Filling in a time card correctly is often more challenging than actually doing the job

thanks lads for your time,im just pulling this up as I get conflicting info I was talking to a fellow welder today and touched on doing a schedule 80 2 inch test. he thinks it would only qualify you up to 2 or 3 times the diameter of the two inch test?? but you say your good for everything greater than 25mm..does that literally mean everything above that diameter?

 

[wheresmejumper]

2 inch schedule 160 i know qualifies you for about the maximum amount of setups possible from 1 test.
Im not too sure about what the maximum diameter is,but i know that plate in the 3g + 4g positions qualify you to weld pipe greater than 2 feet diameter

 

[Dimitri De Spiegeleer]

He's wrong.

 

[chip]

haha thanks dimitri edited to ask can the same be said for wall thickness greater than that of the test piece in this case 2 inch schedule 80 carbon steel?

 

[Dimitri De Spiegeleer]

2" sch80 is what, 5mm wall thickness?
That qualifies from 3 mm to about 10 mm (the double of the wall thickness).

 

[chip]

thanks again dimitri schedule 80 in two inch is 5.54mm wall so that would give me 11.08mm max.
which isn't much.but with that in mind would that 11.08 be the max allowance on anything structural I was to weld?
with the bs 287 coverring pipe and structural it seems a bit tight on the structural side.
when compared with the structural code below albeit 6 inch pipe but gives an unlimited wall thickness.
Although there are many Codes and Standards that govern the welding and testing of Pipe, the one most widely used and recommended at the school is the AWS D1.1 Structural Welding Code.
The test for SMAW is usually a 6 inch schedule 80 pipe with an open root, and is welded in the 6G position. This test qualifies the welder for welding fillets grooves and pipe in all positions. Also qualifies the welder for pipe sizes from 4 inches to unlimited and wall thickness from 3/16 inch to unlimited.
