NDT has nothing to do with cert 10 to AS1796.Welding inspection is not NDT.

Unless things have changed since I took cert 10 in the 80,s then you would need to start at NF17,general cert in welding studies,also probably do a 3E welding test,downhand fillet,vertical fillet , O/H butt and horizontal butt.

Probably need to do metallurgy as an accompanying course.You would need to have pressure vessel experience (AS1210 class1) for the pressure vessel ticket or you will only have a structural cert 10 (AS2214).

There are 4 modules,and you would need to buy or borrow code books,there will be questions on code interpretation.You will need to run welding procedures and do the heat input calculations etc,test welders to the procedures,make sure welds and repairs are carried out to procedure,record weld maps,rod batch numbers etc.Write reports,have mag particle and dye pen abilities,a working knowledge of UT and radiographic principles.

Electrical knowledge,safety,cannot parrallel welders here just in case they are connected in series and you kill somebody.They are shit hot on confined space procedures (AS2865).All in all a fair amount of work.

Hello Geordie

Are you still doing the inspection?

If you are can you give me any pointers on how to get into the game.

Who are you working for?

hi frank
cheers for that..ive started my self training on the mig doing vert ups...gonna have to practice a bit more..can't seem to pause on the sides and although its not a complete abortion, getting undercut on the edges and a big lump in the middle. Gonna find some welding practice books (any ideas) and keep on trying..Never ever, ever, ever again will I SLAG off a welder!! Only joking
cheers trev

hello geordie..where u from in the toon?
Served my time at vickers alot of years ago. Good to see some maggies on here mate

Oops sorry wrong thread

I said MAGGIES..NOT Makems!! :wink:

Hello Trev

Undercut? On the Vert up?

Your not pausing enough on the sides. What process are you using? If its stick, more pause. If it's mig then you need to use a "christmas tree weave".

Vickers? I worked in a few of the factories on the same ind est but never managed to get into Vickers.

hi keel..using mig and was trying to do the xmas tree weave but think i need to pass over the middle a bit quicker as i seem to get most of the weld bulging in the middle...more practice required..suppose im gonna have to kiss goodbye to dinner times for a while!!
Vickers was a good place to work but such a closed shop union wise if i put down more than an inch tack the welders were up in arms!! DEMARCATION!!

As the guy says you are not pausing at the edges,the u/cut is caused by a lack of metal there,it all flows into the middle giving you that bulge.The pause at the side gives the metal in the middle a chance to freeze.Once it has solidified then the pause fills the u/cut.the weld should then have a good smooth and flat profile


The machine may also be a problem,a CDT is the best to learn on,put it on GMAW,the arc length on 0 or minus 1.The GMAW mode sets the arc voltage for DIP (globular ) transfer,the metal freezes faster.Depending on thickness of metel set the amperage for 110 to 150.The amperage is variable by machine,some of them do not read true,check by using the last weld info option on the machine..

On a normal m/c then you need to get the voltage down using the two selectors,try a range of 1 and 9 up to 2 and 3.Learning with 0.9 wire will make it easier but 1.2 produces better faster welds.All m/cs are different so you are not tied to those settings.

Transition from DIP to spray transfer occurs around 22 volts,depending on the shielding gas,you need around 17-21 volts for positional welding and upwards from that for downhand .O/head butt is better with DIP but a fillet is better with spray, on around 23 volts.

A common error in o/head welding is the lumps and general shit appearance of the weld.People then think the juice is too high ,the pool is liquid too long.the opposite is the cause,the juice is too low.

Think of voltage as pressure in an arc.Hold up a garden hose to the sky on low pressure and see how the water dribbles out of the hose and goes wherever gravity takes it. Turn the tap on just a touch more (increase the pressure) and you get a good stream of water for a small distance that defies gravity,o/h welding is the same.That increase in juice gets the metal over the arc and into the plate ,rather than having zero control over it and gravity having control over it.

I come from Chopwell down the Derwent valley,served my time at Swans during the supertanker era,Esso Northumbria on.

Then left half way into HMS Illustrious,halfway up the hangar deck ,welding the O/head butt, the downhand on the butt was the landing deck.I was probably 10 metres back from the ski jump.

I work for myself,semi retired,sick of the game.Some of the small companies need an inspector/supervisor to witness tests,procedure qualification etc,so I go around them.I try to work for 4 days a week and have 12 weeks off a year.

To get into the game get your 1796 cert 10 and then get taken on as a leading hand /foreman and build up from there,it is not a good job.

I liked working night shift so no one was there,most of the blokes never caught on that I wanted so much work done and then they could sleep or drink coffee,do whatever they liked.I only chased threm once, then got rid of them,I didn't want my job to be made hard either.I hated it.

Hello Geordie

Chopwell? I've just gotten off the phone to a mate who lives near Chopwell.
Last time I was there I was doing an orientating competition in Chopwell woods. That is a big wood.

I know where your coming from about being a leading hand/foreman. It doesn't matter who you are you are between a rock and a hard place. That's why I would prefer to get straight into the inspection if possible.

Most places I've worked at since coming over have been small workshops that do not follow procedures etc, so I've not been exposed to all the paperwork that I need to learn. I'm currently working as a boilermaker/pipefitter for Weldtronics in Kwinana Nickol, monies good but again it is not helping with my plan to become an inspecter.

I think that when I get my 1796 (part 10) I will probably have to work away to gain the experience (Karratha or hopefully Bodington).

When I started the course I had hoped to finish up then head back to the North East and work on the new carriers in Swans as an inspecter. But unfortunetly Swans is no more.

Did I meet you at Specialised Welding?

Don't know,I worked at spec weld around 86 when they were doing vessels and spooling for the NW shelf first stage, after the domgas. One of the inspectors for woodside was there to witness some procedures I was welding and a repair procedure.

He heard the accent and we got talking,turned out his brother or brother in law or something like that was my timekeeping clerk when I worked at Swans,when it was denationalised he was part of the management team that bought it.I think they had orders off the govt for type 22 destroyers (Sheffield,Coventry etc) to keep them going,probably straight after Atlantic Conveyor.

Vosper thorneycroft are expecting modules from those new carriers I think,if I was younger I could fancy going back for a year or two to do some work on them.The thought of climbing round a carrier does not appeal at all now.They should be around the 300 metre long mark,the big tankers were around 1180 feet.Rainy day on the Tyne you couldn't see the pointy end from the bridge,the ship disappeared about two tanks aft of the f'csle.
