All you have to do is mark out your centres and centre punch the outside corner and drill the hole, if it still trys to wander put a small drill through first it is that simple

I used a Harrison lathe at tafe when doing my apprenticeship, it was newer than that one square shaped headstock, it also was noisy to run but was a good lathe

Must be pumping some amps in, my arm would fall off going that fast.

Starrett are a great micrometer, but I would tend to stear clear of interchangable micrometers as they dont seem to be as accurate, seems to flex slightly.

Yeah, they may make you do a 6g weld test to get a job but you wont have to do one to get your pressure ticket

Mate to get your tig pressure ticket all you have to do is 2g and 5g and pass them welds to get your certificate 7. Also i cant see any pics?

Just no workshops around here doing the type of work where you need it

Yeah ive done 4 as well but havent done 10, no one uses it around here.

Well done mate. there some good looking welds

I done it at tafe.

TAFE would be the best place to go

Just start the arc and run over the otherside for a little bit before you start adding the filler

Just have a look at what tools the other fellas have that work there and after a while you will find tools that you need, they wont expect a first year apprentice to have all the tools you need. ...

Dont weave at all just try to go straight keeping the bead width the same as you go along the electrode should only be slightly back off 90 degrees. If the rod is sticking you may need to increase...

It is ok to use paper, paper is even used under workpieces on surface grinders to help protect the magnetic chuck, you just got to watch out if there is ink on part of it and not on the other it will...

Try not to add as much filler in that spot, should help

If you are a gun welder and can already weld pipes up perfectly it would be 2 days one day you would do the theory test and another day the practical test, if not most people go to tafe for 2 terms...

Are you talking about pressure welding cert 4 or a course where you get a cert 4 qualification

You can get a drill that size to drill a fair bit oversize easily if the cutting edges are different lengths.

I used 2.4 filler, when i got mine, try to fill it up till near flush then on your cap you can use little filler and go faster and it seems to get a better appearance more shiny looking than dull.

Use 2 runs on the cap will make it easier and help prevent the sag, you will get from gravity. You can use one pass like you have just makes it a bit harder, but from the pictures it looks good,...

Sometimes when you use the two centre method you will be out a bit so i tend to check the throw out with the dial indicator on the shaft.

Are you doing tour certificate 7? If you need any pointers just ask in here.

I find the harder you push the filler into the pool it will change it on the inside of the pipe, so if you push harder you get more reinforcement on the inside of the pipe.

Looks good the only thing i can see which you may have trouble with is the die. You may have some trouble with the pipe kinking on tighter bends as usually the pipe doesnt sit right down in the die...

Probably want to set it higher than 2 on the volt setting we have a 275 transmig and u set it on usually on 3 or 4 to weld 3mm plate so i reckon you will probably need it on atleast 4 on a 195.

There not that harder at all to cut usually When making the nut you will undercut at the start of the nut to the diameter that is needed to give you a guide on depth, just try and work out the...

Why didnt you just cut a slot in the round bar to suit the broach, would of been heaps faster, or dont you have a milling machine?

If the OD of the gear doesnt change and the tooth count changes the pitch is different or a different module gear there are formulas to work out gear dimension and it is always going to be a...

On something about that size as you say it is 32mm diameter i would be running about 1500 atleast for mild and atleast a 1000 on 4140 to get a good finish. With carbide it usually helps going faster...

With 4140 I can get a better finish than with you normal mild steel, you seem to be able to run it slower than mild to get a better finish, your inserts might be a grade not suited for it or...

You should be able to use your boring bar if it can only go in a 16 mm hole you just take your first cut big enough so that the side of the tool doesnt rub against the side you arent cutting, you...

I got that file off the site for you but it wont let me upload it as it is over the site limit so if you send me your email i will send it over. All I did to get it was when it wanted you to join you...

Here you go think it is the right one Fronius TPS Operating Instructions

Sorry if you got the wrong idea but i was talking about the fillet weld, I might of confused you when i said cap pass and thought i was talking about pipe.

Yeah thats the technique I have been using maybe im just not pausing long enough on the sides on me cap, all the other welds i seem to be able to do alright, It is alot easier to do vertical ups with...

Gday, Has anyone done the 8g welding certificate, I am having a bit of trouble with the vertical up fillet. When I run the root pass hot enough to get 100 percent peno the weld is to convex. When I...

CNC's use them as they are better for profiling but there not really designed for heavy roughing, where a square insert or triangle one is a bit more solid.

I have a rubber deadblow mallet but I also have a huckson with the nylon on one end and have a lead end on the other which i made by using a bit of pipe around the size of the usually nylon on the...

I have had a go at it and I found it very hard to see the weld pool, I just tried to keep a steady pass and the slag was real wide compared to the weld put down.

At work we use carbide for general turning and some milling but there is still alot of use for hss as we use it for thread turning and it comes in handy machining plastics etc as you can get a sharp...

Ive seen them welded with the tig they just used stainless filler and hammered it after welding then ground off flush.

Mate I wouldnt waste my money on one all them nuweld welders have real bad duty cycles.

I wouldnt buy one i think if i had a lathe with one on it i would get rid of it, seems like it would be more of a pain, not hard to remember to take the chuck key out.

Well if you cut a slot with a slot drill and cut one with an endmill, the slot drill always seems to be alot closer to size than an endmill.

If you have the modules that you have to complete in your Advanced Diploma of Engineering Technology would you be able to post them up as its something i wouldnt mind doing.

Gday, I aint having a go at you was just trying to show you what was needed to sit for the test, one thing I am wondering about is how you are getting the 340 hrs on 3E and 4 as you only do 80 hours...

Them Cigweld 175 transmigs are a pretty good machine as you can also use them for tig and stick welding and they are pretty good on steel up to about 6mm

Before they even let you try for a as1796 certificate you have to atleast done one of the things below.

Have a AS1796 certificate (1-9) and 40 hours of training using process or

Appropriate...

Before you even attempt doing 3E, 4, 6, 7, 8G, 8F & 9 you would want to do the modules like you do in the trade course, you have to be a very good welder to obtain them certificates.
