FWIW, although cute, many of the welds pictured would not pass a pressure welding examination.

Wow, I didn't know about the extra oxygen usage. Lucky I asked, thanks. I have got quite a bit of money invested in acet gear. Heaps of regs, countless cutting and gouging tips, hoses etc. Maybe I'll...

I have to admit after 20 years in the industry I don't know a lot about cutting and heating with LP gas instead of acetylene. One workshop I worked in was equipped with it and I used it maybe 2 or 3...

By the way I just re read your post and noticed you said that the root is also convex. You will almost never get a flat cap if your root is not flat. So use the same technique i.e. very fast in the...

I found that you have to go across the middle as fast as you can but still keeping the arc burning smoothly. In other words, not too fast or your weld will be a series of stop/starts. Sometimes a...

Yes I was also stoked when I opened up my Fronious and inside it looked more like a computer then a welding machine. Always wonder if I could finish whatever job I'm on if one of the LBT's (little...

I do quite a bit of structural fabrication for houses/buildings and I have to say NewLou is on the money. I weld most steel at around 30v with 1.2 wire. Not sure exactly how many amps that is but I...

BTW you must be old like me, its boc now:q

Yeah, Universal with 1.2 wire.

I'll be using a 400a machine so no probs there. Must be flux core? I've got some inner shield 232 is that ok or does it need to be low hydrogen flux core? I was thinking of actually MIG welding them,...

I need to weld some tooth adapters onto a small digger bucket. I would have thought the best bet is to stick it with Kobe LB52-18 (E4818), out of a rod oven, with 150c preheat on the bucket. But a...

Cotton work clothes regularly catch fire wire welding and oxy cutting. You get a knack of what it feels like when your clothes are on fire. You get a hot wind feeling running up your body, and you're...

lol

You can't hold an arc because the 240v machines generally don't have enough open circuit voltage for cellulose electrodes.

Graham are you sure you have your negatives and positives around the right way? I thought it was opposite.

RC the 18's as Graham said have a little iron powder and have fast freezing weld pool...

In the old days where the term came from, a first class welder was either trade qualified as a boilermaker/welder or held a pressure welding ticket or both. A 2nd class welder was not officially...

True that Glen. I can take my petrol powered 14" quick cut that weighs a ton and is like wrestling on ox when the full load is on the blade, but I can't use a 9":?

I have used King Gee work clothes for a long time now. In recent years I have found their durability has fallen somewhat. They seem more like a handyman or general work ware type of clothing and...

Most 7's are 9's with 7 inch guards on them. As people have said most places have banned 9's and soon that will start being reflected on workers comp and public liability policies. The extra inch all...

lol Adam. Yeah I did actually think of that, or even 'recessing' the genny down into the tray. Which would work well for the issue of weight distribution and rear vision. But then it pretty much...

Thanks for the info guys, sorry I haven't been back earlier. A little quiet again this week so back into it for a bit.

I can't get a photo at the moment cause its at a mates workshop. But its the...

Hello again guys. I need to build a trailer for a generator. I already have a basic chassis and draw bar on an axle. If I go with the conventional box trailer tub design it will be a 2100x1200 (7x4)...

Sounds like a pain. If you could set up something to keep the grinder straight and steady you should be ok. Can you put a grinder disc on a circ saw then onto a triton sort of table?

Surely you...

Brass can be welded with tig or oxy but its a pain in the you know what because the zinc like to burn and boil up. Silver solder is a much better option. And considering you're joining it to steel I...

Sheet on top of ply is hard to get flat and really hard to weld tabs to for jigs and what not. For a metal fab bench imo always go the heaviest you can afford. 8mm should be a good minumum with a...

G'day guys

Since the beginning of the year I’ve been working for myself as a fabricator/welder and I’ve been operating without any insurance cover at all. I need to get covered because of 1) its...

procureit, thanks for reviving the thread. I forgot to report back on my results and how I went about it. The suhner looked the goods but it’s on the expensive side for a 1 off. The one I looked at...

Fossil, I realised only how ambiguous my post was when I read over it. Yes indeed lots of info missing!

The boat is a 6m Haines so its glass, the top will span just over 2m. Length will be about...

Hey guys.
I need to make a hardtop arrangement for a boat. Wondering what size tube is best suited. I was thinking 40x3 round tube but I'm not sure if that's too heavy. If I could get away with say...

No doubt duragal is less fumy than hot dipped, but its still nasty to breath in the fumes. Especially in a closed shop with no fresh air circulation and welding all day. Anyone who has had the 'zinc...

I've welded more gal than I'd care to think of. I hate welding it without grinding for the fumes, the spatter, and the way it welds generally. But if there is heaps to do and its not structural (and...

Doesn't look too bad. Obviously a little unsteady line and travel speed. You'll get that with a little more practice. Get yourself comfy, sit down if you have too, try putting the electrode cable...

Most tafes try to cut expenses as much as they can and so they wont give machined bevels to guys that are just practicing their tecnique. They'll give oxy cut pipes until you have the welds good...

Can you put up a pic of your weld?

Practice running beads down a flat heavy plate first, then try joining together 5 or 6mm thick sections with a fillet weld. Joining together the bar as you...

Hey SWATIG. Are you using 80nb sch40? If so its going to be pretty hard to prepare with just a grinder, especially to be good enough for the No.7. Give it a go if you have to; a 125mm or 235mm...

Mainly only use EN for root runs so you don't burn away the plate/pipe edges, or thin gauge meterial as you said.

Turn buckle?

Nice work mate. Nice beakie mould too :D

I've heard that if a drum contained flammable liquid and you think its clean as a whistle, the seams can still contain some of the liquid. Then when you heat it with a grinder or oxy some of the fuel...

Looking good sleeping wood. Keep us posted on it. What rod did you end up using? I would have recommended a WIA 13S or Kobe 6013 if you can rotate the job around so all the welds are done in the flat...

Stu
Some decent welding there for your first hour. Generally on thin walled tube like that I've found you get the best strength be putting as mush heat as you can without burning through. Once you...

Thanks for all the replies.

I can see advantages in both methods of anchoring into the ground, in this case countersunk bolts into a socket would be best I think.
I will more than likely get...

Sounds good. So you just gotta make sure the threads match right? Any problems with dissimilar metals (s/s to zinc plated)?

Hello lads. I have been in the boiler making industry for about 18 years on and off. I’m back in again and this time working for myself. I look for jobs that I can do by myself and from home or...
