MIG welding Tips

MIG welding stands for Metal Inert Gas Welding. It uses an electrode to produce an arc of electricity over the metal surface. The heat of the electrode melts the metal piece and makes it easier to weld. In order to protect the metal surface from contamination, a layer of an inert gas such is used to shield to metal surface.

Filler metal can also be used if the need arises. The electric supply for MIG welding is mostly of constant voltage, but now alternating current systems can also be used.

MIG welding was initially used for welding aluminum and other thinner metals, but now it is also used for welding steel, carbon steel, copper, nickel, bronze and many other metals.

It is a quick process, gives great results and can easily be used for welding objects that are placed in tight vicinity. Further advancements on this process have made it semi-automatic and research is being done to develop a full robotic welding process based onusing best MIG welder techniques.

MIG welding is an easy and simple process but there are some techniques that must be followed to get a good weld.

MIG Welding Tips

The most important part of any welding process is setting the welding machine. For TIG or other types of arc welding machine settings are not as important but MIG welding machine requires proper settings. You must know your machine well and read the manual before setting the machine.

MIG welding is the only kind of welding that is suitable for all kinds of positions but it really depends on the welder how he sets the welding object and be in a comfortable position to carry out the welding process. A comfortable welding position is the way to get a clean weld.

The length of welding electrode is also important. If the wire stick-out is too long, it will hinder the shielding gas from spreading equally over the metal surface. The flow of gas also needs to be regulated and it must be in balance with the stick out. Too much or too less gas, both will affect the welding process. It is generally advised to keep the length of stick out at 3/4th of an inch and find a good balance of gas flow with this length, according to the circumstances.

MIG Welding patterns are one of the most widely used feature of MIG welding. These patterns can help beginner welders to overcome the lack of skill and get a smooth and uniform weld. There are four welding patterns that are commonly used.

  1. Steady Motion: in this type of pattern you can choose to drag the weld smooth and steady without any sort of changes made to it throughout the line. Conserving this pattern would help you achieve a great weld without any perks or breaks in it.
  2. Whipping. In this pattern you will be moving the weld in a whipping pattern in a consistent way. Moving in the same direction in equal intervals can help you achieve this pattern.
  3. Circles: it can also be a great choice and would result into smooth and uniform weld on the metals.
  4. Weaves: this pattern is better to be used when you need to weld various kinds of metals and joints.

The steady motion welding pattern is most commonly used and is almost an automatic process. The welder must be accurate about machine settings, electrode angle and travel speed. The welder just has to set his position right and let the machine do the job.

Whipping is suitable for beginner welders and it helps them to learn to control the travel speed. Circles and weaves welding pattern works for all kinds of joints. Knowing these basic tips can make you feel easy to weld using MIG welder.

Conclusion

Though its not as simple as it looks still considering these tips to start as a newbie would definitely make you feel familiar with the process and you can work easily like a pro giving consistent welds for sure.
