Bentley


Bentley was founded in 1919, and in addition to being known for its ultra high-end automobiles, also produced rotary engines during World War I. It was purchased by Rolls-Royce in 1931, and the two brands co-existed together until 1998 when they were purchased by the Volkswagen Group. BMW, however, retained the rights to the Rolls-Royce name, and the two brands were eventually split apart in January 2003

Launches next spring, Ford


Ford Racing has announced plans to offer a new lineup of 2.0-liter four-cylinder crate engines.

The first naturally-aspirated engine will be launched next spring and it will feature direct injection and twin independent variable valve timing. Performance specifications haven't been finalized, but Ford expects the engine to produce 160 (119 kW / 162 PS) to 175 hp (131 kW / 177 PS) and 145 to 155 lb-ft (196 to 210 Nm) of torque.

Later on, the engine lineup will be expanded to include EcoBoost (turbocharged) variants.

Mitsubishi Concept PX-MiEV II is the 2013


Mitsubishi is serious about its electrification efforts, it has to offer more than the pint-sized all-electric i in the States. That's where the Concept PX-MiEV II comes in.

What you're looking at is the plug-in hybrid version of the 2013 Mitsubishi Outlander, something Mitsubishi confirms is set to go on sale sometime in 2012.

A traditional 2.0-liter four-cylinder engine is mounted up front, but each rear axle has an electric motor that's fed power by a lithium-ion battery pack spanning the floor. Mitsubishi claims the MX-MiEV II can run up to 31 miles on electric power alone, and if you mash the gas the system switches to parallel hybrid mode by engaging the engine. All told, you should be able to make it up to 500 miles on a single tank, but if you're commute is less than 15 miles, you could go gas-free for months.

Volkswagen began building buzz for the 2012 Beetle long before we caught a glimpse of the first spy shots. The company's executives were throwing phrases like "fun to drive," "masculine" and "Porsche-derived styling" toward the would-be Beetle successor as far back as the 2010 Paris Motor Show. In this business, you either learn to read through hyperbole or choke to death on it, so it goes without saying that our hackles were quivering with skepticism at the time. Volkswagen could hardly blame us.

We had been living with the Type 1C New Beetle for nearly 13 years at that point, and the vehicle had grown into a caricature of itself. Back in 1997, the plucky bubble design was fresh and innovative, but as other automakers began to cash in on the retro design movement, the half-circle Beetle grew very tired very quickly. As a driver, it was merely adequate when it first bowed, and time hadn't been particularly kind to the chassis. Volkswagen wasn't just asking us to stretch our imaginations to cope with the notion of a sporty-looking, engaging Beetle. They wanted us to snap them in two.

Then the 2012 Beetle debuted, and sure enough, the two-door rolled onto the scene with a more vertical windshield and a longer nose. Those two attributes alone are enough to put it more in line with original Beetle design, and, as a result, give the 2012 Beetle a portly Porsche 911 appearance. Car gods help us, we like it, but what about that whole "fun-to-drive" thing? To be fair, there's much more to the 2012 Beetle than a revised nose. The vehicle is significantly longer and wider than its predecessor while riding closer to the ground as well. That's thanks in part to the fact that the hatch now makes use of the same platform as its Golf and Jetta stable mates. All told, the Beetle is six inches longer and 3.3-inches wider than the 2010 model, and those dimensions do much to give the still-retroish hatch a more planted appearance. That doesn't mean that the designers at Volkswagen have excised the pluck from the three-door, though.

Toyota Aqua concepts hint at Prius C possibilities


Toyota unveiled a handful of production and concept Aqua models at the 2011 Tokyo Motor Show. As you may recall, the Aqua will serve as the Prius C here in the United States when it lands at the Detroit Auto Show in early 2012. The Yaris-sized hatchback will come equipped with a 1.5-liter Atkinson cycle four-cylinder engine and an electric motor, though Toyota hasn't said what we can expect in terms of total output. We do know that the vehicle's svelte curb weight and smaller engine will likely translate into Prius-besting fuel economy numbers, so buyers can look forward to over 50 mpg in the city.

The brightly-colored Aqua Kiriri Version and Aqua Piriri Version joined the production Aqua under the lights in Tokyo, giving the world a better idea of what the model could offer in terms of dealer modification. The little hatch looks sharp, and the fuel economy figures are enough to make anyone grin.

girl of mig welding show


sales promotion girls should be able to market a product and explain its superiority. for example on car products. spg could explain that the car was assembled using mig welding techniques are very powerful. Until no visible defects, iron builders feels light and soft, invisible even nickel alloy, that's greatness oxy laser welding machine in a perfect result. MIG welding is useful because can use to weld many different types of metals: carbon steel, stainless steel, aluminum, magnesium, copper, nickel, silicon bronze and other alloys.

She explained The primary advantage of MIG welding is that it allows metal to be welded much quicker than traditional welding "stick welding" techniques. This makes it ideal for welding softer metals such as aluminum. When MIG welding was first developed, the cost of the inert gas (i.e., argon) made the process too expensive for welding steel. However, over the years, the MIG welding process has evolved and semi inert gases such as carbon dioxide can now be used to provide the shielding function which makes MIG welding cost effective for welding steel.

 This is a basic guide on how to weld using a metal inert gas (MIG) welder. MIG welding is the awesome process of using electricity to melt and join pieces of metal together. MIG welding is sometimes referred to as the "hot glue gun" of the welding world and is generally regarded as one of the easiest type of welding to learn.

**This Instructable is not intended to be THE definitive guide on MIG welding, for that you might want to seek out a a more comprehensive guide from a professional. Think of this Instructable as a guide to get you started MIG welding. Welding is a skill that needs to be developed over time, with a piece of metal in front of you and with a welding gun/torch in your hands.
MIG welding was developed in the 1940's and 60 years later the general principle is still very much the same. MIG welding uses an arc of electricity to create a short circuit between a continuously fed anode (+ the wire-fed welding gun) and a cathode ( - the metal being welded).

The heat produced by the short circuit, along with a non-reactive (hence inert) gas locally melts the metal and allows them to mix together. Once the heat is removed, the metal begins to cool and solidify, and forms a new piece of fused metal.

A few years ago the full name - Metal Inert Gas (MIG) welding was changed to Gas Metal Arc Welding (GMAW) but if you call it that most people won't know what the heck your talking about - the name MIG welding has certainly stuck.

MIG welding is useful because you can use it to weld many different types of metals: carbon steel, stainless steel, aluminum, magnesium, copper, nickel, silicon bronze and other alloys.

Here are some advantages to MIG welding:

  • The ability to join a wide range of metals and thicknesses
  • All-position welding capability
  • A good weld bead
  • A minimum of weld splatter
  • Easy to learn
Here are some disadvantages of MIG welding:

  • MIG welding can only be used on thin to medium thick metals
  • The use of an inert gas makes this type of welding less portable than arc welding which requires no external source of shielding gas
  • Produces a somewhat sloppier and less controlled weld as compared to TIG (Tungsten Inert Gas Welding)

first.. you know about mig welding


MIG (Metal Inert Gas) welding, also sometimes called GMAW (gas metal arc welding), is a welding process that was originally developed back in the 1940's for welding aluminum and other non-ferrous metals. MIG welding is an automatic or semi automatic process in which a wire connected to a source of direct current acts as an electrode joins two pieces of metal, as it is continuously passed through a welding gun. A flow of an inert gas (originally Argon) is also passed through the welding gun at the same time as the wire electrode. This inert gas acts as a shield, keeping air borne contaminants away from the weld zone.

The primary advantage of MIG welding is that it allows metal to be welded much quicker than traditional welding "stick welding" techniques. This makes it ideal for welding softer metals such as aluminum. When MIG welding was first developed, the cost of the inert gas (i.e., argon) made the process too expensive for welding steel. However, over the years, the MIG welding process has evolved and semi inert gases such as carbon dioxide can now be used to provide the shielding function which makes MIG welding cost effective for welding steel.

MIG Welding

Gas Metal Arc Welding (GMAW) is frequently referred to as MIG welding. MIG welding is a commonly used high deposition rate welding process. Wire is continuously fed from a spool. MIG welding is therefore referred to as a semiautomatic welding process.

MIG Welding Benefits

* All position capability
* Higher deposition rates than SMAW
* Less operator skill required
* Long welds can be made without starts and stops
* Minimal post weld cleaning is required

MIG Welding Shielding Gas

The shielding gas, forms the arc plasma, stabilizes the arc on the metal being welded, shields the arc and molten weld pool, and allows smooth transfer of metal from the weld wire to the molten weld pool. There are three primary metal transfer modes:

* Spray transfer (MP3 Audio)
* Globular transfer (MP3 Audio)
* Short circuiting transfer (MP3 Audio)

The primary shielding gasses used are:

* Argon
* Argon - 1 to 5% Oxygen
* Argon - 3 to 25% CO2
* Argon/Helium

CO2 is also used in its pure form in some MIG welding processes. However, in some applications the presence of CO2 in the shielding gas may adversely affect the mechanical properties of the weld.

Common MIG Welding Concerns

We can help optimize your MIG welding process variables. Evaluate your current welding parameters and techniques. Help eliminate common welding problems and discontinuities such as those listed below:

Weld Discontinuities

* Undercutting
* Excessive melt-through
* Incomplete fusion
* Incomplete joint penetration
* Porosity
* Weld metal cracks
* Heat affected zone cracks


MIG Welding Problems

* Heavily oxidized weld deposit
* Irregular wire feed
* Burnback
* Porosity
