Here are some more information for Tungsten Electrode:
Professional welding actually involves expertise & experience. A fairly extensive-knowledge is required to become an expert. Many years of exposure & skill are necessary to master the art of welding. After understanding the basics, one can learn more complicated skills.
First and foremost, one has to take safety precautions. Otherwise, unforeseen circumstances may even prove to be fatal. Damage to the eyes is a possibility due to intense light beams that emerge from the course of action. As electricity is involved in certain cases of welding, death by electrocution is a possibility. Before starting welding, helmet has to be worn for protecting eyes, hair, head & face. Wearing protective gloves & clothing is a must.
Arc Welding:
Arc welding is the most common technique used. It is the first lesson for welding. Instead of using a gas torch, high voltage electricity is to be used. In arc welding, a spark/arc is able to melt a metal & form a weld. This process is accepted by many as it is more accurate & produces a cleaner & stronger weld. In the category of arc welding, seven different methods are there to choose from.
Shielded metal arc welding may be the most suitable if you have large welds or metal welding in not-so-normal angles & positions. In this method, the electricity passes through an electrode using which metals can be melted. MIG welding (Metal Inert Gas welding) will be useful in a welding project which requires more speed. In this method, rods need not be used. In its place, equipment has to be used that passes current through a metal tip that does not melt. A separate piece of continuous wire is to be fed to the tip which forms the weld. Tungsten inert gas welding is slightly similar to MIG welding. It is applicable in thin materials where high quality weld is required & where speed is not necessary. There are other methods also - namely Flux-Cored arc welding (FCAW), submerged arc welding (SAW), plasma welding etc.
Aluminum Welding:
Aluminum is the most difficult alloy. Initially, aluminum oxide should be cleaned from the surface. Heat treatable aluminum alloys receive their strength from a process called ageing. Notable decrease in tensile strength will happen when welding aluminum due to over-ageing. For all other information on aluminum welding processes, please visit the homepage or any of the links connected to this.
Aluminum alloys can be divided into 9 groups.
Designation Major Alloying Element
1xxx unalloyed (pure) >99% Al
2xxx Copper is the principle alloying element.
3xxx Manganese is the principle alloying element.
4xxx Silicon is the principle alloying element.
5xxx Magnesium is the principle alloying element.
6xxx Magnesium & Silicon are principle alloying elements.
7xxx Zinc is the principle alloying element.
8xxx other elements (including Tin, some Lithium compositions)
9xxx reserved for future use
Aluminum alloys are readily available in the market. We can get them in various product forms. The following are the factors affecting aluminum welding.
* Aluminum Oxide coating.
* Thermal Conductivity.
* Thermal Expansion Coefficient.
* Melting characteristics.
Other welding Methods:
There are some other methods - resistance welding, energy beam welding & solid state welding. All these methods are useful in industrial applications where large scale & specialized requirements are involved.
What we have dealt with so far are only basic concepts. These are the fist lessons or fundamental steps from which on can go further to acquire more knowledge about welding procedures. One has to remember only a couple of basic methods. One has to practice a lot before arriving at a standard of excellence. Certain processes will bring easy results & some may not. Sooner or later, one will reach a stage & style which will be most comfortable for future operations.

What does Carbide Stand for in Tungsten Carbide Ring?
What does the ‘carbide’ stand for in tungsten carbide ring? You have heard that tungsten rings are ‘unbreakable’ - that they are made from one of the hardest substances on earth. You may have heard that tungsten rings do not scratch, or that they keep a ‘like-new’ polish for their entire lifetime. Much of the fantastic stuff you hear about tungsten comes from the presence of the ‘carbide’. To understand how the metallurgy works to create such beautiful rings we will need to start at the beginning.
Tungsten is one of the hardest substances known to man, and amazingly made stronger when combined with carbide. When pure tungsten is mixed with a carbon alloy the resulting metal alloy rates between 8.5 and 9.5 on the MOHs hardness scale (only diamonds are harder at a rating of 10). The mixed tungsten and carbon alloy becomes known as tungsten carbide and is used in a huge variety of products and tools – x-ray tubes, light bulbs, welding electrodes, turbine blades, high speed tools, grinding tools, golf clubs and even bullets. All of these ‘practical’ items are the reason it took so long to get around to using it for tungsten carbide rings.
When jewelers began to try and work with tungsten carbide they quickly discovered that the process would be much more like cutting a diamond in the rough than the usual process of shaping metal. In fact, there are almost 30 steps between beginning and finishing a tungsten carbide ring. Working with metal this hard isn’t easy, but the end results justify the effort. Rings of unprecedented durability and beauty emerge from the rough metal. Polished tungsten has a very deep shine that will stay for life – tungsten rings never need refinishing.
A tungsten carbide ring will last a lifetime and beyond. With the addition of carbon alloy, amazingly, tungsten becomes even stronger and more durable. You have heard great things about tungsten, but to truly appreciate this quality metal you need to feel and see a ring for yourself. You will be impressed by the ring’s weight and feeling of liquid satin in the hand. You will be impressed as well by the deepness of the shine and how light plays across the highly polished surface. Soon you will be the one, showing off your new ring, and talking about the fantastic properties of tungsten carbide rings.

I am doing an electrolysis project and i am wondering if anyone knows y tungsten duznt work as an electrode?
Tungsten has a very high resistance. The speed of the electrolysis process is contingent on having a high current, and the resistance of tungsten kills this current. Think bout an incandescent lightbulb. Those have tungsten filaments, and the resistance is great enough to cause most of the energy to dissipate as light and heat.
I suggest using graphite rods from a 6V dry cell. Those have some resistance but less than tungsten and they are just as immune to corrosion.
New catalyst for hydrogen fuel cells resists CO contamination
(PhysOrg.com) -- Hydrogen fuel cell vehicles promise faster refueling and the ability to travel longer distances before refueling than battery-powered cars, but they are susceptible to poisoning by carbon monoxide (CO). Now, scientists in the US and Japan have created new nanoparticles catalysts that enable hydrogen fuel cells to resist CO poisoning.
