Here are some more information for Welder Aluminium:
"Aluminum? What's that?" This is the first thing a British person would say when coming across this word. Then, they might say "Aha, you mean Aluminium; because as everyone British person knows aluminium is spelt with an i, and there's no such thing as aluminum."
Then again an American would look at the English spelling and make funny noises as well. Al-um-in-ium, they might say in inverted commas. "Are you trying to be funny or something? These Brits with their strange sense of humour."
And we'd both be wrong. (But we would never admit it.)
In 1812 a British scientist Davy proposed the name aluminum for the metal and only later agreed to change it to aluminium to conform with the typical "ium" ending of other elements. It is really only the British and the Americans who oppose each other so fiercely over aluminium or aluminum. And, of course, the Canadians agree with the Americans for a change.
Most other English speaking countries use the terms interchangeably. In fact for most of the nineteenth century Americans also used the word aluminium, but try going round the States these days going aluminium, aluminium. You won't get very far. But, of course the Americans put the emphasis on the second syllable, while the British put it on the third (correct me if I'm wrong), and that is another reason why the word sounds so wrong.
But then again if an American approached you in London and asked for the rowout (meaning route, pronounced "root" in England) to the Houses of Parliament you'd probably be stuck for words for a while as well.
You say aluminum, and I say aluminium.

Pontoons Are In Favour – Part Two
Have you ever seen that advertisement on television where a Tigger character from Winnie the Pooh comes shooting out of a boat in the background? Have a closer look next time and you will see they are on a pontoon. Pontoons have become a very popular means for a group of people to enjoy themselves on the water. Their style, use and outfitting have come a long way since the floating deck was first built in 1951.
This was made out of steel barrels welded together to form two cylindrical airtight pods placed side by side onto which a wooden deck was built. However a further development was to use aluminium for the floats instead of steel. There were several reasons for this. Aluminium resists corrosion, can be cast and extruded, is a good conductor of both electricity and heat and it is light. The result was a longer-lasting lighter structure.
Briefly, aluminium is the most abundant metal in the earth’s crust. It is found primarily in bauxite ore which exists in enormous reserves and, in places, is still in the process of being formed. This is happening in tropical countries like Brazil, Australia and West Africa. Gibbsite is one of the ores in bauxite. The gibbsite in the older bauxite deposits dries out, leaving behind boehmite and diaspore. It’s the means by which an older or newer deposit is defined. Being so plentiful and replaceable puts it in a remarkable position. It is environmentally friendly and can also be recycled indefinitely without damage to its structure.
By the way, there is a theory that cooking utensils made from aluminium, more specifically pots and pans, could damage your health. Possible problems were thought to include damage to the central nervous system, dementia, loss of memory, listlessness and severe trembling. There have been numerous medical conferences to discuss this theory but no definite conclusions have yet been reached.
Extracting aluminium from bauxite requires huge quantities of water, which accounts for the first plant being sited at Niagara Falls in 1901.
The first pontoon company, built by Mr. Weeres was ’sold on’ and apparently one of the deciding factors in its purchase by the new owner was the workforce. Welding aluminium is a precision skill, so a group of trained welders was a big plus. Building different sizes, and improving and expanding their outfitting resulted in the business moving into export markets, keeping in the forefront of its competitors. Customers now have a wide choice and boats are streamlined to suit the size of all purses.
Pontoons are used for a wide variety of purposes. Houseboats are built on pontoons. Helicopters use pontoons platforms as landing pads. Sea-planes use pontoon floats to land on water and it is now possible to buy a small helicopter kit which uses pontoon pods as its skids enabling it to land both on water or the ground - great for adventure enthusiasts.
Because pontoons have a shallow draft (they do not lie low in the water), damage from submerged items or running aground is less likely to occur. Therefore they are found as ferries at river crossings in out-of-the-way places, like Kazangula on the River Zambezi between Zimbabwe and Zambia. The load is usually not more than a truck and three or four cars, plus foot passengers.
Their low upkeep costs and their low comparative cost per sq footage make them less expensive to insure even if they have a 190 hp engine attached to drive them. This also means they make an attractive rental businesses.
Some individual fishing pontoons are of innovative and unusual design. They can be inflatable or otherwise and can be viewed at this site.

Is there any advantage between scratch and lift type tig welders?, eg welding aluminium?
I use a stick welder and mig but prefer the mig, unless welding thick (+5mm) steel, are the results with a tig any better than mig
OK so you want to know what the difference is between Scratch Type and Lift type tig welders?
Scratch type - are called scratch type as you must make the electrical circuit to enable the arc to start. The welder can only supply a running voltage to the tungsten electrode in the hand piece so once you scratch it, it starts. BUT there is a draw back to this - when preforming scratch starts when the arc starts there is a small amount of pollution that occurs as the surface of the material you are welding is vaporised, it's very small amount but it shortens the life of the electrode and in some cases when welding exotic alloys like Titanium and Inconel can cause dirt or debris inclusion in the start of the weld, as you can image these materials are used in areas where strenght is a requirement no one wants a dirty weld, it wouldn't pass inspection which would lead to part failure.
Lift Type: - A lift type TIG welder has a secondary circuit that supplies a very high frequency voltage to the tungsten electrode, you are able to hold the tip of the electrode about 2 mm away and upon depressing the foot switch the 'High Frequency Circuit' activates causing a small arc to jump from the tungsten electrode to the work (dependendant on polarity and workpiece material) this arc is only a few micro seconds in length and is controlled by the HF Circuit once trigged the welder then supplies the main welding voltage as a piggy back onto the HF circuit allowing you to weld at you preset amperage. The advantage? No contamination of the work piece or the elctrode, HF circuits can me used to do fancy things in TIG welders such as 'Crater Fill' where the main welding amperage is reduced then spiked to allow the filling of small holes or undercuts in welds.
The only draw back is really in price, getting a decent welder with an HF circuit usually means a lot of money but you get some other useful features such as water cooled nozzles for working all day!
Hope it helps, happy welding.
Roll up, roll up, for the dirtiest show in town
During the 1987 election, the Conservatives' campaign coordinator and Margaret Thatcher's favourite minister, Lord Young, conceived the idea of hiring an airship, painting a Tory logo on the side, and flying it over every town the Prime Minister was on her way to with "Maggie's Coming" in giant flashing letters underneath.
