They are now suing both Signal and the recruiters, who are also being sued by Signal which claims that they misled the company as well as the workers.Just west of Pascagoula, in Gulfport, a group of Brazilian welders and pipe fitters have made similar allegations against another marine-fabrication firm.
The metal's detrimental effects on human health may be subtle but widespread, contributing to diseases known by other names.For the past ten years Brad Racette, a neurologist at Washington University in St Louis, Missouri, has been tracking those effects, paying special attention to welders, since they are exposed to more manganese than most people.
Ron Foster, the logistics manager at Mtwara's port, says his company looked for 25 locals to train as welders but found only two who were suitable.
Crossrail (a link through London), the 2012 Olympic games, an enormous housing development in London's Thames Gateway and the dismantling of old nuclear reactors will all absorb welders, joiners, engineers and raw materials, pushing up costs and leaving less for new nuclear plants.The biggest problem, though, is a shortage of qualified scientists, engineers and technicians.

Between January and April this year, according to Mr Richwine just 30 welders took the course; the company was looking to hire 70.Similar tales could be told of the experiences of Brevini, an Italian maker of wind turbine parts, and Magna, a new car-parts maker.
This has helped some displaced workers find new jobs as welders, for example, or dental assistants.
Interestingly, says Dr Racette, the miners are on average exposed to less manganese than welders are in the United States.The number of brains autopsied is still too small to provide convincing evidence that manganese causes PD.
The results are not always happy ones.Signal International, a marine-fabrication firm, brought around 500 welders and pipe fitters from India most of them from the southern state of Kerala, many of whom had laboured in various Arab Gulf states to work in its shipyards in Pascagoula and Orange, Texas.
So specialised, in fact, that Bob Richwine, the head welding teacher at the college, said he had never heard of them, and so difficult that only experienced welders could attempt them.
Many of the region's industrial and building firms complain that it is hard to find competent welders.
