Introduction

MIG (Metal Inert Gas Welding) or Inert Gas Welding. In the process the electrodes are melted and mixed with molten parent metal to form a weld pool. Thus, the electrode must be supplied constant current throughout the welding process is carried out.
For a continuous supply of electrodes, the electrodes are made in the form of wire to be extended out from the nozzle welder automatically at a specified speed. Protective gas is supplied through the nozzle weld as is done in TIG welding. This process can be done automatically or fully automatically. However, the
MIG equipment more complicated because the process requires continuous huluran uniform electrode. Gas Metal Arc Welding or Gas Metal Arc Welding (GMAW) is also known as Inert Gas Metal Arc Welding or Metal Arc Welding (MIG) MIG Welding is widely used in industry because it is easy to maneuver and can weld various types of metal and various metal thickness. MIG welding is widely used in manufacturing industry, automotive industry including aeronautics industry. other than carbon steel, MIG welding can also be used to weld aluminum and stainless steel (stainless steel). MIG welding electrodes supplied in different wire loop with the other electrode welding rod or rods supplied.

The basic principle of MIG welding

In MIG welding, an electric arc is formed when the wire electrode in contact with the base metal. Arc produces heat that will melt the base metal and the electrode tip. San molten base metal electrode mixed form and mixed molten pool when welding cold to produce moldings. Electrode wire without coating supplied continuously (in the form of a loop) through the wire feed unit. Supply of inert gas shield arc and molten pool from atmospheric air.

Objective

* In order to improve the quality or skill in welding.

* The real way to know how to weld with inert gas welding and accurate

* Knowing how to weld properly.

* In order to familiarize themselves in welding while making industry training and preparation for the job when due.

Safety precautions

* Wearing protective clothing while in the workshop as hand protector, shoes security, face shield or the like.

* Use good equipment only.

* Make sure knows how to operate a machine before using it and if they do not know how to handle it, do not try to use it.

* When operating the machine, no need to wear decorative devices such as watches.

* Ensure that all the steps followed when operating the machine use machine.

* No kidding when operating machinery.

* Ensure adequate ventilation systems.

* Ensure adequate lighting system.

* Must know the main switch (main switch) workshop event of an accident such as electric shock, turn off the switch on

Safety clothing Clothing | Function | faceguard | -Protect your face and eyes | gloves | -Protect hands from welding splashes | safety shoes | -protect the feet from injury-for example if there is a light metal that fell hit the legs, feet will not suffer injury | shirt workshop | -protect against welding splashes |

Shooters work Equipment | Function | MIG machine | - Provides current to perform welding work | MIG shooter | -remove wire electrode to perform welding | string elektrod | -supplying electrodes and metal smelting | Berus iron | -clean metal surface to look smoother | clamp | -to hold metal plates | Oil | - Refrigerate and protect nozzle shooter |

Procedure Run moldings 1. Clean the place to be in welded with steel brush.

2. Connect the grounding cable on the welding table or metal to be welded.

3. Place the workpiece on the table and set the appropriate flow and pressure plate and adjust the current in MIG machine.

4. Perform MIG welding by pressing the trigger shooter from end to end with an angle and the distance from the object to complete the job right.

5. MIG welding machine switch off and close the gas pressure upon completion of welding run moldings and cool the workpiece.

6. Clean the surface of the workpiece by using a tool such as a brush cleaner wire to get the updates.

Discussion

In the completion of both projects, I need the right techniques and the right to produce a neat project and the right to what is required. In addition, for this project I also need to comply with safety measures to avoid unwanted accidents such as burns and so on. Among the security measures I need to follow is, I must wear safety equipment such as aprons, eye protection tools, gloves and so on. I also must ensure that the voltage and current used are suitable for welding work done. In addition, listen to the advice of lecturers is also important because without my lecturer would not be able to complete this project successfully.
Proper technique can produce the required project is also included in what I have to obey. If I ignore this rule, the projects I produce will be flawed. For example, when you want to weld, the two metals must be cleaned and clamped that during the welding process do not move the workpiece. Weld nails need to be done to fix the position of the metal plate before welding is done completely for a solid connection and easy to carry out the welding process.
Finally, when everything is over I have to follow the discipline is to store and organize return the equipment used in the set. Not easy to make this simple project if we do not learn his techniques right and we must always practice so that we can produce a quality project.

Conclusion

In conclusion, for the completion of this project MIG welding requires proper techniques and extensive experience. The use of tools also need the right techniques to get the best and quality projects. I also get exposure to the MIG works for preparation in industrial training and later working life.
Many tools are available that are not quite perfect as iron brush, eye brush is worn out and the iron can not be used with care. Equipment bay less than the number of students who produced the project and this will be produced on time to the project. There are many students who joked during the welding process to do, this will endanger students because the probability of undesirable things are great. Students with exposure on how to use MIG machine and this will affect the quality of the work done.
Monitoring lecturer needed by students due to students not familiar again using welding equipment. This is very important and also to avoid unwanted accidents because students do not know the ins and outs of welding equipment condition. MIG welding with a little too much to train me to be more careful and follow the rules set forth in my daily life.
