If you notice quality of MIG welders have come down as most of them are manufactured in Eastern Europe and China. If you buy cheap MIG welders you have to compromise on functionality. The major advantage of buying a slightly more expensive welder is that wire feed control automatically varies according to power. Wire speed knob does not require fiddling when you change power settings. If you buy one of these you will never regret. In addition, if you buy a slightly expensive welder you can get a good sized feed motor and a quality wire feed mechanism. If you buy an expensive MIG welder which will cost somewhere around £200 to £500 you can avail more benefits in the long run. Generally expensive welders have two controls –one for power and the other for wire speed. Another control is spot timer.

MIG WELDING – An overview:
Friday, August 20th, 2010MIG welding was originally developed in 1940 for welding aluminum and other metals. Main advantage of this welding is metal can be welded much faster than traditional welding techniques. It can weld softer metals like aluminum. When MIG welding was first developed, cost of inert gas made the process too expensive for welding steel. In addition, it also produces long continuous welds much faster than traditional welding methods. MIG welding produces a clean weld with very little splatter. MIG welding can be used with a wide variety of metals and alloys. This type of welding is commonly used in the automobile industry because of its ability to produce clean welds and it can weld metals quickly. People favor MIG welding as it is much faster and saves time. The operating cost is lower and it can adjust to limited electrode length and this allows for longer welds with fewer interruptions.
Different types of welding:
Thursday, August 19th, 2010Welding is nothing but a process of joining two metals. Welding can be done through gas flame, electric arc or laser.
MIG (Metal Inert Gas) welding is an automatic or semi automatic process where wire is connected to a source of direct current acts as an electrode joins two pieces of metal as it passes continuously through a welding gun. One major advantage is that metal can weld quickly than traditional welding. Other advantages are – since shielding gas protects the welding arc, MIG welding produces a clean weld with very little splatter. MIG welding can be used with a wide variety of metals and alloys.
Tungsten inert gas (TIG) welding is the process of blending together reactive metals such as magnesium and aluminum. TIG welding is commonly used for both high quality and manual welding. There are different types of joint used with TIG welding like butt joint, lap joint, corner joint and t-joint.
Advantages of Mig welders:
Monday, August 2nd, 2010Welding is known as the most difficult and unsafe job. There are many ways for welding metals. But welding should be done carefully otherwise these are harmful for the welders. The most popular welding is the mig welding. These are cost effective as well as consumes less time for welding metals. These welds are capable of welding all kind of metals. Mig welding is a process where electric charged is fed to the welding arc. There are few reason why mig welder are popular than other welders.
• These are very simple to perform even difficult task.
• This uses lesser time for welding any kind of metal than the other type of welding equipments.
• These are less expensive and can be afforded by any fabrication companies.
• These utilize any shielding gas for giving smooth finish.
• The speed of mig welder is faster than other welders. There is no need to change the rods and because of this it produces quality welding.
• These are also used for welding thin metals.
• The mig weld can be processed either manually or automatically.
MIG welding wire types
Monday, June 28th, 2010In metal fabrication and production, the MIG welder is commonly used owing to its versatility and efficiency. To control the amount of filler metal added to the weld puddle, the MIG welder uses welding wire fed from a spool. Diameter, alloy and type are used to categorize the MIG wire.
It is necessary that the alloy of the MIG wire must match the base metal being used. This would ensure that a strong weld would not crack or weaken when cooled. As a wide variety of alloys are available for MIG welders, welder would have the option to weld carbon steel, stainless steel and aluminum. A MIG welding wore would have the name of the alloy, diameter and type of the wire marked on a label. The label would be visible while attached to the welding machine as it is located on the side of the wire spool. Even though the wire type would be marked on the label, each manufacturer has a different way of making wire type. The two distinct type of MIG welding wire are the solid core and the flux core. Solid core MIG wire is a solid strand of the chosen alloy while the flux core MIG welding wire has a flux paste inner core would be surrounded by the filler metal.
What are mig welders utilized for?
Thursday, June 24th, 2010Welding a metal is a very tough work but due to advancement in technologies the work of welding has become very easy. One of the important welders used for welding is Mig welder. This welding is a semi automatic arc welding where continuous electrode and shielding gas is feed. This melts the metal faster than other welding equipment. This tends to melt the soft metal like aluminum easily. These are capable of welding all kinds of metal.
The work of this welding is much faster and it also saves times. The process of this weld is very neat and produces less splatter. These are capable and used by the farmers, construction field and the automobile area. The merit of this weld is they are inexpensive and long performance. The three property of this welding equipment are gas, voltage and speed of feed. All the three things are to be set properly other wise the welded metal won’t have good finish. The metals are welded in one time and it doesn’t need to change the rods.
Welding joints and its basic types
Wednesday, June 2nd, 2010When you are learning how to weld, you first need to study the types of welding joints there are. The main reason you have to learn these joints as if you are on a big job and you have to study the blueprints you will require to know the symbols and the name of the weld joint to be capable to situate the part that needs a weld on it.
The 5 weld joints are called Butt joint, Corner joint, Edge joint, Lap joint and Tee joint. The first one called Butt joint is a joint that is between two members lying around in the same plane. The second one named Corner joint has two members placed at right angles to each other in a form of an angle, generally 90 degrees. The third one named Edge joint is a joint between the ends of two or more parallel members. Fourth one is a Lap joint, which has two overlapping members to form the joint. Fifth one is the Tee joint; it looks just like it is called because it forms a “T”.
When you produce weld ments, it is essential to combine types with weld types to produce welds. And they will produce a name like, prepare welds, plug or slot welds, spot or projection welds, seam welds and the listing goes on and on.
Highlights On Mig Welding
Tuesday, May 25th, 2010Feed welding is the other popular name for Mig (Metal insert gas) welding. Other popular names for this weld technique in weld industry are like Gas Metal Arc Welding (GMAW or Metal Active Gas (MAG). It is one of the fastest and simplest techniques of weld.
The method of welding is semi-automatic or automatic. With the helping of welding gun wire electrode and a shielding gas is fed into it continuously. Apart from this Argon gas is also conceded in welding gun along with the wire electrode. This is done so as to achieve the desired results. This technique is mostly employed in high production and welding operations.
MIG welding operation can be carried on metals such as stainless steel, copper, carbon steel, and aluminum. All these metals can be weld in this process and moreover it can be performed in every position with the help of shielding gas, electrode, and welding conditions. This weld technique is popular in automobile industries. The gas which is fed in it acts as a shield agent protecting the weld zones from the contaminants of air borne. While performing this weld operation welder has to follow safety tips to protect him and others too.
What is MIG Welding and what are its Types
Thursday, May 13th, 2010MIG welding is expanded as Metal Inert Gas. This methodology of welding is popularly known as Gas Metal Arc Welding. The process involved in MIG welding is to make use of the aluminum alloy wire along with the blend of filler material and electrode. This process is carried on by the welder who is well averse about the facts of MIG welding and its types in it. This weld procedure is one of the simplest procedures.
Any person who is willing to learn this process of weld can learn it as it is very easy to handle the weld. Metal Inert Gas welding is also termed as semi-automatic weld as for the reason most of its welding procedure is carried on with the help of machine which is specifically designed for this purpose.
There are two procedures in MIG welding. They are:
- Weld by Conventional Metal Inert Gas – this weld technique is best suited to mold the materials whose thickness is above 4mm.
- Weld by Pulsed Metal Inert Gas – this weld technique is best suited to mold the thinner materials and this can be carried on in any position of weld.
Tips for Newbie MIG Welders
