Types of Mig Welders

mig weldersThere are various types of welders  but there is one in particular which is used much more than others. One of the most used welders  is the MIG welder which unlike many other types is a wire feed welding machine. This is in contrast to welding methods that make use of a stick or electrode, and it is generally much more efficient for general purpose welding.

When looking for a MIG welder you will generally hear it called by a number of different names and sometimes it can be difficult to tell exactly what it is you are purchasing. That being the case, take this list into consideration when you are looking for a MIG welder, and remember that a MIG welder by any other name is still a MIG welder:

  • Metal Inert Gas (MIG)
  • Metal In Gas
  • Gasless Mig Welder
  • Wire Feed Welder
  • Mas Metal Arc Welding

Process Notes

Throughout the welding process the weld puddle will be shielded by a gas known as the Inert Gas or Active Gas. It is possible to use a wire without a shielding gas, and this process will be known as Gas-less wire Welding. Argon Gas is the most common type of shielding gas used in because it does not have any reaction to the MIG welding process and is therefore safe to use.

Gas-less MIG welders are normally only used by home users who operate outside on a regular basis. Note however that these can also be used on job sites and other outdoor locales. The benefit of using a gas-less MIG setup  is that one would not need to worry about wind blowing the shielding gas aside and creating a hazard during the welding process.

Uses

MIG Welders can be used for a number of different applications. For instance you will find that they are used in both the professional and personal circles for virtually any project. From professional vehicle plants to the garage where you are working with wrought iron, these types of welder have a home anywhere.

Power Requirements

Meeting power requirements for the purpose of a MIG welder is not difficult so long as your working area meets the standards.

Power Approximations:

Single Phase MIG Welder: 230-250 Volts

Three-Phase MIG Welder: 400-420 Volts

The power outlet for a MIG welder will need to be considerably bigger than your standard outlet. This of course is to handle the start up current, or that initial power surge as you activate the device. Note that industrial machines will create a larger power surge, and there is a strong chance that you have seen these outlets on several other devices around the house. The majority of standard house plugs will not have the amperage to handle a MIG welder which means you will need to seek out higher amperages. If you are not an experienced electrician it would be in your best interest to call on professional help.

 

MIG Welding Basics

MIG welding stands for metal inert gas welding. It was originally used to weld non-ferrous metals such as aluminum. It eventually was used on steel too. It is a quicker method of welding as compared to other methods of welding.

mig weldingSome of the advantages of MIG welding include the speed of the welding process. It has the ability to weld many metals and many thicknesses of metal. The biggest advantage to MIG welding is that it can be automated so that the human element can be removed all together. That’s why robotic mig welders are commonly found is on an assembly line in an automobile factory. As mig welding machines utilize a wire feed system this makes them ideal for robotic purposes as they can carry a great amount of filler rod or wire.

Mig welding utilizes a wire feed technique which feeds a wire electrode from your welding handgun to the weld. This wire electrode is available in numerous coil capacities or spools dependent upon the welder sizing, that may contain 100s and perhaps 1000s of feet/meters of wire. The actual wire feed includes a pair of drive wheels to the wire plus a continual speed electric motor to move the drive wheels. The majority of Welders contain numerous features enabling timed feeds together with adjustable speeds.

You need the right safety gear. This includes a face mask to protect your eyes and skin. You also need to have a heavy leather jacket. Keep the jacket fastened all the way up. You need to wear heavy cotton pants and close toed shoes. Heavy work boots are best. Make sure that you are welding in a well ventilated area, and that you have some kind of barrier between you and others, and you have a warning sign that advises people to avoid the area.

When you start welding you need to make sure that you have the valve on the machine for the shielding gas is open. Your welding machine needs to be on, and the grounding clamp either on the metal or on your welding table.  Make sure that your metal is clean and sharp edges are ground down. Clean edges make your welds better. You can bevel the edges to create a valley for the weld if you choose to, this is more important on thicker metals.

After you have done that and set your machine up, it’s time to start welding. You want to make a zig zag or concentric circles with the tip. It’s smart to practice before you start welding. Make sure the mig welding machine is at the right setting. If you are getting holes in your workpiece your setting is too high. Your settings are too low if your welds are being formed in spurts. You have the right settings when your bead is nice and smooth.

Welding Types and Processes

welding types An outline of welding types and processes commonly used in industry and manufacturing

Micro Welding, represents systems and also devices specifically designed for the purpose of carrying out, as it implies, micro welding  for very small, thin, and fragile components by making use of closely managed heat energy.

Laser welding, is certainly one of the leading approaches the metalworking industries, because focused energy from laser device produces a higher quality of weld. lazer welding may also be used for many additional applications  such as cutting, drilling, sealing, as well as scribing,  helping to make the process itself, multi purpose in nature.

Seam Welding works as a resistance welding procedure that creates a weld on the faying surface areas of overlapped components along an overall length of the joints. The weld can be created by overlapping weld nuggets, a consistent weld nugget or through forging the actual joints as it’s heated up to the welding temperatures by means of resistance to the flow of welding current.

Ultrasonic welding is often an industrial method in which high-frequency ultrasonic  oscillations are utilized to weld items together, usually plastics,  This specific form of welding is required to produce components and also parts  which are so tiny, complicated, or even far too fragile for any common welding methods. In ultrasonic welding, no other conecting techniques or glues required to bind materials with each other.

Hermetic welding is a welding procedure that doesn’t create a weld yet generates a seal. The primary point with hermetic welding will be to produce a complete leak-proof joint, which in turn cannot be offered via other standard welding process.

Projection welding can be described as flexible procedure designed for joining wire, sheet, machined & formed components in steel, for example  wire mesh, connection for mounting brackets, and so on for sheet metal construction, as well as welded nuts and bolts

Orbital welding apparatus has the capacity to produce premium quality, dependable welds regularly as fast as possible
A good orbital welding process is going to significantly outshine manually operated welders, numerous times paying for the cost of the orbital machines within the job.

Precision welding isn’t a specific welding procedure, but alternatively a collection of welding systems which opperate on a micro level to produce high quality welds . Precision welding is required on situations in which normally can be challenging to get in the regular approaches with welding. Almost all of the innovative styles of welding procedures drop within the class connected with precision welding.

Resistance welding consists of the creation of heat by means of transferring current through the resistance induced by the contact with the metal surfaces. Pools of molten metal are formed at the weld area as high current  is passed through the metal. Resistance welding comprises of the common welding types such as Arc, Mig and Tig welding
