Maybe the Brian's lathe problems in another thread are down to China working to German quality standards then Alan.

My own collet chuck problems are similar – didn't realise that the aspect that is wrong matters or maybe just couldn't be bothered.

Japan was a touch different. All exports were checked to meet certain standards and they managed to produce goods with all round acceptable performance at much lower cost than the west. Many bits had a "quality" sticker on them – reassuring if nothing else. Factually they were generally inferior products to what the west produced but at 1/2 or under the price and able do what ever it was meant to do, well that sort of thing always wins in the end. They also most definitely dumped to gain market share. They also propped up the USD for a long time. China's foreign reserves seem to be falling rapidly but it's hard to find out how many USD they actually have. At one point getting rid of them would have cause the USA a lot of problems.

Taiwan deserves some comparisons with China too. The same thing will probably happen to China eventually but given rather a lot of them and communism – rule by technocrats – it could be a very very long time coming. Possibly never.

Africa, The Chinese are already investing heavily, cash and political capital.

I must admit I don't visit the site that often and have n't read Brian's thread , but as John S's trip to China a few months back made clear , China gives you the choice. You can buy cheaply and get reasonable quality at staggeringly low prices, or you can pay something nearer western prices and get top quality.

I must admit I do have some admiration for the Chinese based on a lot of history. Despite being the biggest boy in the class for centuries they have seldom bullied , the Tibetan "invasion" being their only transgression in some eyes .although there is little historical doubt the Tibetans were for most of history seen as a province of China paying homage to Beijing. The Chinese I presume did not subscribe to the view that anything had changed this.

Remember also they signed a deal to lease us Hong Kong for 100 years and honoured the deal fully , even though they could have walked in at any time. I don't think Margaret Thatcher would have done a Falklands had they done so. Do you ? You would think that any nation with our record in China would keep very quiet about human rights and moral superiority .

As for their track record for hard work and technology contributions its been going on since before the Ming dynasty. Anyway this is n't metal , but neither is making cracks about the Chinese.

No, they've been investing in Africa for 20 years, we'll have to wait our turn (it's MOD 4)

Two or three (maybe more)years ago, the NZ Railways had a large number of rolling stock built in China(cheapest tender), they could have been built in their own (NZR) workshops, on arrival in NZ they were inspected, and found unfit for service, they were taken from Auckland(port of arrival) to the workshops in Dunedin, the welds ground out and redone, I think the total cost far exceeded the cost of building them in NZ. No doubt if a higher price had been accepted from the Chinese, the waggons would have been OK. Over 100 waggons I think. Similar(not welding) problems with some locomotives.

Well, getting back to the original topic…why is everyone so negative about the idea of a welding simulator? Simulators in other fields have been shown to aid in training..the airline industry for one. I saved a lot of balsa wood learning to fly radio controlled planes by using a simulator. That is not to say that I did not sacrifice any real planes in the learning process, but I am sure that the simulator helped a lot. Sure, it is not the same as the real thing, but it does not have to be to be useful, it just has to be good enough to help get you on the right track. You can use up a lot of materials learning to weld, so anything that can reduce the cost has to help.

The real future is with high end kit which will change the current and/or voltage, wire speed and gas flow to compensate for operator error so that basic welding will really be no more difficult than slowly moving the torch along the joint. The best welds are already made by robots…

Neil,

[Not that it matters] … That is roughly the scenario I had in mind when I made my first response; and I was even pondering the possibility of working [very?] remotely.

But; this forum being what it is, I was [it appears] accused of making anti-Chinese comments.

[nigel jones 5Participant @nigeljones5]

I didnt read it as anti chineese. And if it was, well we still live in a vaguely free country, for now at least.

[Neil WyattModerator @neilwyatt]

Elsewhere you will notice the curious background to the comments that fired all this up.

Hopefully things will calm down a bit now and we can address the matters in hand.
