The most significant components and fittings of TIG welding

Friday, January 21st, 2011

Most of the TIG welding equipment consists of gas device with controller and many of the element present they are welding torch, power cable, tungsten, electrode, gas nozzle this are the different types of elements is present, and also welding power source, motionless gas cylinder this are the elements present in this process.

Most of the welding torch consists of cooled air or else water if the welding current is more than 150 amps the air or water gets cold.

The filler rod is mainly used for heavier welding metal and the metal must have similar chemical of metal piece. The filler rod comes in two ways they are either in straight fixed lengths or coils.

Distinction between TIG welding and MIG welding

In welding some of the techniques are used to join the metals deposited in one place without the help of equipments. TIG welding indicates gas tungsten arc welding. MIG welding indicates gas metal arc welding. This is the one of the differences between TIG welding And MIG welding.

Advantages of TIG and MIG welding

MIG welding is useful and it is gifted in small number of establishments and discontinues and it is useful for long time welding. The welds should be clean and clear involving for cleaning the MIG welding. TIG welding is useful and it is gifted with filler metals or else without filler metals. The MIG welding needs the filler metals otherwise there is no spray formed at the time of TIG welding.

Tig welding offers various benefits:

Thursday, January 6th, 2011

Even though TIG welding may not be suitable for all types of welding requirements but it has a number of benefits. There are number of tasks that entitle for code needs such as piping, nuclear work and high profile customer goods regularly want at least the prime bond in the pipe joint to be TIG for an efficient weld. For a number of things the entire passes on a multi-pass pipeline joint might have to be TIG, if high feature and system requirements insist it.

Often, TIG welder will be a superior quality fuse compare to a MIG welder and it is the broadly acknowledged fact in the welding technology. Let us see one example- Suppose a small assemblage inside a car engine is prepared of 3.2 mm aluminum. Even though MIG welding will surely do the work quickly but the engineers like to use TIG process because it is known for accuracy. At the time when you are choosing TIG welding machine, you have to know how much energy and sophistication are required for the job.

All about TIG Welding and its Fame:

Thursday, December 9th, 2010

Let us know little more about TIG welding and its popularity. It is a type of welding in which an arch is produced between a non-consumable tungsten electrode and the metal that is being welded. The arch generates the necessary heat to thaw the metal and the defending gas, fed via the torch stands as a shield by keeping, oxygen in the air, away from the dissolved weld pool and the hot tungsten.

Tungsten is utilized in favor of the electrode because of its high liquefying heat and excellent electrical characteristics. A detach space filler rod is fed inside the arch stream either manually or automatically, at the time when filling metal becomes compulsory. As there is no need of any flux, the bond joint is clean and free or canceled. Tig welding is an extremely perfect process that provides very clean bonds without any splatter and little amount of smoke.

It makes the work very attractive for vastly aesthetic applications, such as automotive, monument, experimental jet and various other home-hobbyist jobs. Normally, TIG welder is being utilized in applications that contain thin-gauge elements of stainless steel, chrome-moly tubing or illumination metals like aluminum and copper alloys.

About TIG welding:

Monday, November 8th, 2010

In TIG welding, tungsten electrode heats the metal that you are welding and gas protects the weld from airbone contaminants. If you notice TIG welding does clean welding on any type of metal. It is non-consumable tungsten. Shielding gas protects weld and also produces high quality, clean welds.

Benefits of TIG welding:

• TIG welding can be used to weld steel, stainless steel, nickel alloys, magnesium, copper and even gold etc. It can also weld wagons, bike frames, door handles, fenders and more.

• TIG can create clean welding. Since filler metal is added to the welding puddle, no spatter or sparks are produced.

• As argon protects the weld puddle, no flux is required or used in TIG welding. Also, finished weld will not have slag to remove between weld passes.

• TIG welding does not create smoke or fumes. Do remember to clean the base metal before welding.

• Because Argon can be used to TIG weld all metals and thicknesses you will require only one type of gas in your shop to handle all your welding projects.

• TIG welds can be made in all positions.

Benefits of TIG Welding:

Wednesday, October 27th, 2010

• TIG weld helps in welding thin metals such as aluminum. It is able to weld thin metals as it leaves no slag or flux after the welding process.

• It can weld any positions whether it is flat, horizontal, vertical or overhead. The main reason it can be welded in all positions is because it does not create sparks or slags.

• TIG Welding only uses one Argon gas for heating the welded material and electrode. Using TIG welders is safer as welder has to store only one type of gas in the workshop or trailers where welding is being done.

All about TIG welding:

Wednesday, October 20th, 2010

Tungsten Inert gas (TIG) is one type of arc welding. It is used for complex and stylistic welding on a variety of metals including copper and titanium. TIG welding uses a tungsten electrode to direct the welding arc onto the work piece. TIG welding requires the use of a shielding gas to push air away from the weld. Argon is used as a shielding gas for TIG welding. Because the electrode does not provide filler material like other arc-welding processes, a separate welding rod or wire rod or wire has to be used if filler material is needed to complete the weld. Push method is best for positioning the electrode. Electrode is held at a 10 to 15 degree angle from vertical and pointed towards the direction of the weld. The welder uses the electrode to create a small pool of molten metal and then pushes the metal forward with the electrode in a cyclic motion, adding filler material as needed.

KNOW THE BENEFITS OF TIG WELDING:

Thursday, October 14th, 2010

The process of TIG welding is like an arc welding process. The process of TIG weld is termed to be more complicated than other arc-welding processes in view of the fact that there is a close tolerance than that is actually required. The process would require a shielding gas so as to push the air away from the weld. Push techniques is considered to be best for positioning the electrodes.

Benefits from TIG welding

1. It offers superior quality of welds
2. The process of weld can be carried on with or without use of filler metal
3. There is a accurate control on welding variables (heat)
4. The weld is free from spatter
5. TIG welder will observe low distortion.

Shielding gases used by TIG welder’s are

• Argon
• Argon/Helium
• Argon + Hydrogen

The main purpose of using shielding gas (typically inert gas like argon) is to shield the weld from corrosion and from other impurities.

The main purpose of adding up helium gas is to increase the level of heat input which in turn increases the speed of welding or the penetration of weld. Whereas the usage of hydrogen gas is to showcase the results of cleaner looking welds and it is also useful for increasing the input of heat.

A short summary on TIG welders:

Friday, October 1st, 2010

TIG welder uses a non-consumable tungsten electrode, which acts as a torch, and melts the metal. This can weld 2 thick pieces of metal together without using filler. It is mostly found in motorcycle shops and garages for welding frames of bikes and cars together.

Important points to remember:

• With the help of TIG welding you can make a clean weld and it also produces less smoke and fewer fumes for a healthier work environment. Different types of metals can be welded by using TIG welders than other electric arc welders.

• It can weld any new type of materials.

• Higher quality weld joints are possible in a full range of TIG welding positions.

• TIG welding was invented to build magnesium airframes for aircraft industry.

Tig welding- what you need to know:

Friday, September 17th, 2010

Tig welding which is also called as gas tungsten arc welding produce clean precise weld on any metals. Tig welding is used to weld stainless steel, copper alloys, magnesium and aluminum. Higher quality and stronger weld made this welding process a little comparative than other welding processes such as mig welding and arc welding. Tig welding is in practice from 1941 and it utilizes a non consumable electrode called tungsten electrode. Aerospace industry and automobile industry use this welding technology and it welds more metal than any other process.

There are several different types of joints are used with TIG welding and it includes butt joint, lap joint, corner joint and t-joint. The butt joint can be welded without the assistance of a filler rod and two pieces of metal are joined together. Aluminum is the metal that is associated most frequently with tig welding.
