MIG welding, as most of us are aware, is a semi-automatic arc welding process in which a continuous, consumable wire electrode and a shielding gas are fed through a welding gun. At the end of the gun, there is a contact tip which passes electricity to the wire. Both the wire and shielding gas are activated to create the weld when the operator depresses the trigger of the gun.

Pros of MIG welding

MIG welding is quite popular as it is easy to learn and calls for no special skills. Even a first-time operator will be able to achieve a good weld with minimum practice. People favor MIG welding as it is a much faster than Stick welding and saves time. Thus operating cost of MIG welding is lower than Stick welding because of this saving of time. MIG adjusts to limited electrode length and this allows for longer welds with fewer interruptions.

Besides, there is also no waste of filler metals and generally speaking, thinner materials can be welded far more easily with MIG than Stick welding. One more reason people favor MIG welding is because MIG welding is a tidy process and does not require chipping slag as in Stick welding. MIG certainly makes for very convenient weld tacking and fitting of parts and there is very scant stub loss due to the continuous spool of filler metal.

MIG welding is versatile and capable for a variety of applications, including – trailer hitches, auto body repair and restoration, farm/ranch equipment, household projects, repairing wheel barrows, bicycles, etc. This type of welding demands less time when compared to other types of welding processes.

Cons of MIG welding
The initial cost of MIG set up is high in view of the regulators and shielding gas – though some MIG welding may be done with self-shielding flux core and without gas or a regulator.

It is indeed a fact that all types of material can be welded with a MIG machine. But, in the MIG process different materials require different wire and gases. For instance mild steel can be welded with either self-shielded wire or with CO2 or a CO2 mixed gas but aluminum material requires the use of Argon gas.

It is inadvisable to weld through dirty materials with MIG machines. It is said one should always weld on the cleanest possible material, so for best results scrape off paint, rust or other debris where the weld is being made.

There is no denying that MIG welding equipment is more complex, expensive and less portable and the welding gun is difficult to maneuver. Filler metal can become tangled within the wire feeder making the operator feel annoyed and also adding to downtime. The operator has to patiently keep leads and liners in straight position to allow for proper feeding of filler metal.

Summing up
When electrically charged wire is feeded into the welding arc then it is MIG welding. MIG is commonly preferred because the welding leads are very easy to perform. As a matter of fact, it is said that even robots can be utilized to get the mechanical job done. MIG welder is capable of working with almost all kids of metals, though aluminum and mild steel are the most popular ones.

Brazing process exudes fumes, emissions and radiations that may be harmful for the people involved in conducting and managing. The people working in this industry are exposed to gases and harmful radiations that are exuded by the brazing of the base metals and the filler metals. The emissions can affect the workers, physically because of the sparking in the process and can cause respiration problems as well. Physically the body parts – nails, hair, eyes, skin – exposed to these sparking fumes and gases might get affected. Brazing safety measures should be adopted to combat these hazards.

To ensure complete working safety for the brazing workers, safety equipments have been developed. These equipments must be worn by the workers while conducting brazing. They save not just from the hazardous side effects, but also make it comfortable.

Leather Body Suit

A leather body suit is designed for people who are involved in bonding techniques like soldering, welding and brazing. It saves the body parts from sparks and heat caused by brazing. It is a made of non-flammable and heat resistant material. A body suit must be worn over the normal daily wear clothes for complete body protection.

Gloves

Gloves are not included in the body suit. And should therefore be separately arranged for and worn. Gloves are very important as your hands are the amongst those parts of the body to the that are closest to the brazing area. Leather gloves are again heat and fire resistant, and a must safety equipment.

Shoes

Just like gloves, shoes should also be made out a similar material. Apart from being close to the sparks, feet are also exposed to distant sparks flying down or any hot substances on the floor. Special shoe coverings keep the feet safe.

Brazing Glasses

Blazing glasses are also available, made out of special material for protecting the eyes from the harmful radiations produced by the excessive heating.

Helmet

Heat, radiation and chemicals fill the air in the surroundings and cause harm to the facial skin and hair. Inhaling of these gases is also harmful for our respiration system. It is advisable that every worker should wear helmets for complete protection through the process.

As most of us are knowledgeable of, MIG welding machine is a semi-automatic arc welding work in which a perpetual, breakable conductor electrode and a defending gas are supplied by implementation of a welding gun. On the tip of the gun, there is a conjunction end which delivers electrical energy to the wire. Mutually, the shielding gas and the wire are set in movement to create the weld when the mechanic lowers the induction of the gun.

On the separate ability, there are advantages as well as disadvantages of MIG welding machines. Read on and discover from the succeeding areas of MIG welding.

Advantages of MIG welding machine

MIG welding is evenhandedly well-liked as it is individual to benefit noesis of and calls for no exceptional skillfulness. Even a first-timer operational will be competent to accomplished a high-quality weld with smallest quantity of use.

A lot of grouping holds MIG welding machines; it is an extraordinary time-saver. Hence, the working cost of MIG welding is decrease than Stick welding because of this circumscribe of indication. MIG regulates to several degree of electrode length and permits for long welds with lesser disruptions and intervals.

In addition, there is also no utilization of filler metals and thinner materials are welded with no hassle with MIG welding machines. It is also an orderly work and does not require chipping scum. This certainly makes for extremely eligible weld tacking and furnishings of parts and there is improbably slight scrape thrashing because of the incessant revolve of filler metal.

MIG welding is doubtless convertible and competent for a variety of claims, including – automobile body amend and improvement, trailer hitches, unit projects, farm/ranch equipment repairing machine barrows, bicycles, and others. This kind of welding insists not as more of lasting term when compared to advance sorts of welding procedures.

Disadvantage of MIG welding Machines

The origin outlay of service up a MIG welding machine is soaring considering the shielding gas and regulators though a few MIG welding may be finished with self-protecting compactness core and without controller or gas.

In the MIG process, various materials need various gases and wire. Plus, it is not advisable to weld through grimy materials with MIG machines.  MIG welding should constantly weld on the cleanest material.

MIG welding machines are also many multifarious, expensive and fewer moveables and the welding gun are solid to move. The filler metal can be knotted within the wire feeder making the functional appear roiled and also adding up to downtime. The operator has to uncomplainingly maintain liners and leads in a continuous line or position to hold for appropriate of filler metal.

MIG welding happens when an electrically charged wire is fed into the welding arc. MIG is ordinarily favorite for the conclude that the welding leads are often simple to carry out. In measure of fact, it is said that even robots can be used to accomplish the motorized job realized. MIG welder machine is competent of working with most of all kinds metals; even if mild brace and aluminum are the most in style ones.
