I'm also a beginner and the thing I found most difficult when learning tig was fillet welds. I'd suggest using thicker steel (2-3mm) to practise on as it's more forgiving, also get the hang of laying down beads and butt welds before moving on to fillets. I found using a smaller ceramic cup...

Dont take it that something is clean if your just giving it a quick wizz over with a flap disk, all abrasives do it, grinding wheels, soft pads etc etc, but some of the finer grit flap disks are very good at picking up paint and lacquers, then as the disk comes around and back in touch, smearing...

Does any body have any time welding Fecralloy and InCo 625 that has been thought a few 800c heat cycles. I have come in to a new job in the last 10 weeks and have seen some god awful welding from the lads Im working with I'm not saying there bad welders at all but the stuff is just nasty to...

im looking for some advice on welds please if you would be good enough, i had a few goes at tig with a parweld 162 now and the equipment is slowly starting to feel a bit more comfortable "just found out that the torch head can be bent to suit my grip which i think has helped " i started by using...

Your dead right Chris. You should never shorten a tungsten by snapping them as they will likely crack down the length and split during use. If you must shorten them then they are cut on an abrasive disc. Preferably a thin one that's gonna get through it quickly and not generate too much heat.

get hold of a cubitron flexible grinding wheel [green]eats tungsten like butter, be easy to make an enclosed guard with a guide for the pin chuck have you tried the oxy acetylene trick hold a 3.2 tungsten in the pin chuck full length vertical. wearing your welding helmet start heating the...

The cutting slot is already suitable for that purpose :)

What about drilling a hole to a certain depth somewhere on the tool to act as a setting gauge. Insert tungsten till it bottoms out, slide on pin vice and tighten, remove tungsten and pin vice and transfer it to the grinding hole.

Searching the internet for thoriated tungsten millisieverts will get a few relevant hits. I've only scanned through it but https://www.bghm.de/fileadmin/user_upload/Arbeitsschuetzer/Fachinformationen/Schweissen/BGI_746e.pdf has a few estimations of radiation exposure in it like For...

Below is a cut and paste from a google search, it is quite clear from article, particals produced by tungsten prepping operations, produce the highest risk to the tig welder and, those within vicinity of grinding operations. I have no idea how old article is, clearly the Danes are phasing/phased...

Multiply "a few per day" by a few decades, it all up to potential nasty ingestion. I'll look into they other types you mention, see if I can mooch some samples?

Anyone inclined could use a geiger counter to scare people about all sorts of things from Brazil nuts to flying abroad or moving to Cornwall. I don't care if thoriated tungeten is banned or not, i just really hate the stupid scare tactics used to market the alternatives. Especially given that...

Fair comment, but with inverter technology, many of the characteristics you mention are possible using safer, non radioactive tungstens. "Why change" from personal experience, not many companies have tungsten grinders with extract fitted. As mentioned in previous post, maybe if we all ceased...

What sort of turning are you planning on doing and how much? I just use the standard carbide inserts and they last well and keep things simple. If making special one offs I'd just use tool steel. I hardly use my grinder if I'm honest but good to have when needed.

I have a water stone wheel that spins at 90 RPM for sharpening knifes, chisels etc. I need a new general purpose one for using and abusing, however ive also been told that I need another one with some sort of "Green" wheel for grinding tungsten carbide lathe tooling that I will be making soon...

Just be aware of the speed compatibility.

I would like to ask the advice of you good people who have some experience of the above.I need to grind down welds in some inaccessible places and am looking to buy a die grinding bit which I hope to fit to my router (which unbolts from its springy frame/fence device).I would like to ask what...

@ Dazza, This afternoon whilst cleaning up the wooden work bench i was dismayed to find far too much carborundum dust off the coarse grinding wheel where I've been pointing up the tungsten electrodes using my battery drill , then I had a brain wave or a brain collapse ( You decide ) . I think...

If you use a single grinder that is used for all your metal grinding you risk embedding particles of other metals in your electrodes according the the Eastman video . I guess using a dedicated fine face grinding disk in a 4 " angle grinder could also give you good results so long as the thing is...

I don't have a bench grinder or cordless drill, up until now i've been using grinding bits in my bench drill with poor results.
