All you Need to Know About TIG welding

Tungsten inert gas welding (TIG) also referred to as gas tungsten arc welding is a metal joining process where welding heat is generated by an electric arc formed between the workpiece and a tungsten electrode. The electrode used is non-consumable, meaning that it does not melt during the welding process. There is also no filler material required in a majority of cases, but a welding rod may be used if necessary. TIG equipment among the favorites of Cromweld.com are usually used to weld aluminum alloys. There are various additional pieces of equipment needed for TIG welding. The main ones include a power source, TIG torch, and shielding gas supply system.

Power Source

A power source is needed to enable the welding process. The source needs to supply power with high current, both direct and alternating current. Direct current is mostly used for mild steel, stainless steel, titanium, copper, and nickel alloy, among others. For magnesium, aluminum, and aluminum alloy, alternating current is used. The power source usually consists of electronic controls, a rectifier circuit, and a transformer. Proper arc generation requires a voltage of between 10 and 35 volts at a current of 50 to 300 amperes.

TIG Torch

The main parts of a TIG torch include tungsten electrode, nozzle, and collets. Air or water is used to cool the torch. The tungsten electrode is held in place by a collet. The diameter of collets varies depending on the width of the tungsten electrode. The nozzle helps to direct the flow of the shielded gases and the arc to the welding zone. With a small cross-section, the nozzle enables a high intense arc to be produced. The nozzle also needs to be replaced regularly as the spark produced causes it to wear out.

Shielding Gas Supply System

The shielding gas usually used is argon, though other inert gases may also be used. The shielding gas is used to ensure that the weld does not oxidize by ensuring that oxygen or other gases do not get into the welding zone. The inert gas that is used is selected based on the metal that is to be welded. A supply system is used to regulate the inert gas flow that goes to the welded zone.welding arc

Working

First, the power of high current and low voltage is supplied to the tungsten electrode, usually connected to the negative terminal. The current provided then forms a spark between the electrode and workpiece. Heat is produced from the arc, which then melts the base metals and forms a joint. An inert gas is passed through a regulating valve and a pressure valve into the welding zone to shield the weld from oxygen and other gases.

Factors To Consider When Buying A Light Bulb

It is a universal fact that light is very important in our daily lives. That is why if there is a blackout for few ours, your moods will take different directions.

For you to find the right bulb for your home, there are some of the factors that you need to consider. Here are some of those factors.

Watts and lumen

jhgfewqwedrftThis should be the first thing that you should always look at before buying a bulb. Watts measure that amount of energy that is required to light the bulb. On the other hand, the lumen is a term that is used to describe the amount of the light that is produced by the bulb. When you go the shop make sure that you buy a bulb that has the lowest watts and the same time high lumens. Such bulbs are of high quality, and they have many benefits one of it being that they do not consume lots of energy. This, therefore, means that you will be able to save a lot of cash when it comes to paying of the electricity bills. Also, the quality of the light produced by this kind of bulbs is impressive.

Color rendering index

Another important factor that you should also put into consideration is the color index of the bulb. When you hear about the color index, it is a word that is used to describe how light source makes the color of the object to appear to the human hear. The color rendering index ranges from zero to hundred. So here the higher the scale, the better. CRI is a feature that most people seem to ignore. However, if you want a perfect illumination of you home, then you need to make sure that you put this factor into consideration.

Voltage

fghhgfdsYou also need to look at the voltage of the bulb that you want to buy. This is what will give you the maximum efficient that you will desire as long as the lighting of your home is concerned. It is recommended that whenever you go to buy a bulb, ensure that the voltage on the bulb matches the supplied voltage of your fixture. You also need to understand that low voltage draws lots of currents and also high voltage reduces the life of the battery.
