Hybrid_From_Hell Posted February 7, 2015 Share Posted February 7, 2015 For thos who might find this useful, print and pin up Seen loads of explanations on TIG Tungstens, most made me not much wiser still having Qs ...then I found this : TIG_TUNGSTENS.pdf TIG_TUNGSTENS.pdf Quote Link to comment Share on other sites More sharing options...
robertspark Posted February 7, 2015 Share Posted February 7, 2015 nice post, must be the Australian version ...upside down... Quote Link to comment Share on other sites More sharing options...
ejparrott Posted February 7, 2015 Share Posted February 7, 2015 You have to print it and pin it up 'cos it's upside down!Must remember to print one out ready for when I start Quote Link to comment Share on other sites More sharing options...

Team Idris Posted February 7, 2015 Share Posted February 7, 2015 I got some red ones free with my welder, so I popped them in a draw. I don't know how radioactive they are, but I'm sure grinding the tip down should be done witha proper tip sharpener! Quote Link to comment Share on other sites More sharing options...
robertspark Posted February 7, 2015 Share Posted February 7, 2015 UK Version.pdf Nige sorry... sarcasm, couldn't help it, needed a laugh... could have done the obvious and turned the monitor upside down... ...when I nod my head hit it!

robertspark Posted February 7, 2015 Share Posted February 7, 2015 I got some red ones free with my welder, so I popped them in a draw. I don't know how radioactive they are, but I'm sure grinding the tip down should be done witha proper tip sharpener! the quote I believe is "mildly radioactive".... i.e. don't breathe the dust in probably a better link than the general discussion one below: http://www.twi-global.com/technical-knowledge/faqs/health-and-safety-faqs/faq-the-use-of-thoriated-tungsten-electrodes/ http://www.gordonengland.co.uk/sef/Thread-Hazard-of-Thoriated-Tungsten-Dust-Arising-from-Re-grinding-of-Electrode Quote Link to comment Share on other sites More sharing options...

CwazyWabbit Posted February 7, 2015 Share Posted February 7, 2015 So that all translates to .... buy 2% lanthanated as they are good for everything and then that way you don't need a pile of different tungstens I got some red ones free with my welder, so I popped them in a draw. I don't know how radioactive they are, but I'm sure grinding the tip down should be done witha proper tip sharpener! I wouldn't worry about it too much, I assume you aren't welding everyday with them? As Robert said they are mildly radioactive and you have to inhale of injest the dust as alpha radiation can't penetrate the skin. The risk of cancer in TIG welders due to thoria exposure is very low, since the exposure times to individuals are invariably small. The Danish Welding Institute estimates that of 1200 full-time TIG welders, a cancer incidence of 0-3 may occur during a thirty year working life. While this figure is considered acceptable, the Danish Welding Institute has recommended that thoriated tungsten be phased out in Denmark since non-radioactive alternatives are available.

ejparrott Posted February 9, 2015 Share Posted February 9, 2015 Thanks Nige!I think we were using either blue or grey when I was doing my course Quote Link to comment Share on other sites More sharing options...
mickeyw Posted February 9, 2015 Share Posted February 9, 2015 Interesting. I have a box of thoriated electrodes from when I used to TIG at work, a long time ago. I find they make very good scribers these days Quote Link to comment Share on other sites More sharing options...
Lewis Posted February 9, 2015 Share Posted February 9, 2015 I'm using thoriated, I have 20 or so to get through whilst learning, once I've stopped dipping the electrode and sticking the filler to it quite as often I'll splash out on some blue multistrikes 1 Quote Link to comment Share on other sites More sharing options...
