  2. MIG welding: the basic procedures

    MIG welding is often used in everyday life, even by amateurs who work in their hobby shops and not only by commercial welders and industrial welders. That is why it seems that we should give some explanation on the basic MIG procedures and practices.

    It is always good to go on a welding school, welding community colleges or on a welding course for one week or several weeks, especially if pursuing a career in welding. If the MIG Welding is just a hobby, then a few basic tips will do. Yet, to be on a safe side, if you want to be a welder, it is better to visit a one week class for welding beginners and hobbyist.

    In general, like every commercial welder will let you know, the MIG welding is the easiest of all the welding processes that exist. In order to learn the basic procedures in welding, it will take just a few hours. Yet, if you want to be really good at MIG welding,

  3. Introduction to MIG Welding

    MIG welding is now quite a popular form of welding and many people now know and recognize the term. May be this is so because of the Monster House of Jesse James or the American Chopper and the rest of the cable TV shows that are referring to hot Filler Rods, Mig Welding Equipment, etc.

    This attention to the MIG Welding has resulted in many new MIG welders and commercial welders, but also in the enthusiasm of different people who decided to use mig welding practices in their shops and garages. In general, the MIG welding is not hard to learn and the materials are quite affordable to buy. That is why many people, of course including industrial welders and commercial welders, are now striking arcs and learning how to burn.

    There is something that we should say about the safety or rather about the lack of safety on many of these shows. The people who have decided to do some MIG Welding should know that grinding should always be done with eye protection. Besides that, the

  4. The MIG welder 115 volt field test

    Every commercial welder and each industrial welder is tested for MIG welding.  The test is known as the 115 volt field test. There is a special 115 MIG welding machine, which is a good option for the welder who wants to weld with shielding gas. This machine is welding with a 3/16"" thick tee joint with multiple passes, where the machine is plugged into a 10 amp 30 foot reel extension cord. This is not a very good practice as the commercial welder should not use a light duty extension cord with a MIG welder, but it can happen in reality.

    So, what happened? The result was a small 20 inches straight sputter after welding. The welding could be fine when it is used a self-shielded flux core Lincoln nr211. In other words, the tests proved that the commercial welder cannot predict how a MIG welding machine will behave and weld just by looking at it, without trying. The MIG AHp welder that has been used did

  5. All about TIG vs. MIG Welding

    Which welding should you opt for?

    Despite their almost similar names, TIG and MIG welding have some differences owing to factors such as welding precision, setup times, initial cost and utilization.

    TIG Welding

    TIG stands for Tungsten Inert Gas - a welding that joins reactive metals with the help of a non-consumable Tungsten electrode. It utilizes Argon, an inert gas, to produce a weld without air contaminants. Tungsten creates the arc between the electrode and metal. Optionally a filler may be used if required. 

    Pros of TIG Welding:

    Its cleaner and good for the environment. This is because it gives off the least spark smoke and fumes.

    It also results in more precise welds since TIG welding has less contamination.

    There's also no need to use filler materia as TIG welding can easily let one weld melt into the other. Its good for thin materials.

    Cons of TIG Welding:<

  6. Welding Rods and Their Classification

    TIG welders, Arc welders, MIG welders, and Stick welders who work with wires, know that when the wire is cut and is straightened, it is called a welding rod. That is a form of filler metal or filler wire which is used by the multiprocess welders in the process of brazing or welding that does not conduct the electrical current.

    As the Arc welders, TIG welders, Stick welders, and MIG welders are aware, when the wire is used in the electrical circuit, it is called a welded electrode and it is defined as part of the welding circuit and actually through the welding electrode is conducted the welding current. Usually the electrode is a welding wire, yet it can come in other forms as well.

    The multiprocess welders know of several systems that are applied for the classification of a certain welding wire, rod or electrode. In all those cases is used a prefix letter which indicates something. So, here it is how the welding wire classification goes: when the prefix is R it indicates

  7. Welding Processes and their Power Supply

    There are many welding processes that apply power supply and which are presented in this article. One of the most popular welding processes that commercial welders perform these days and which had great usage in the past decades is the arc spot welding. The advantage of this type of welding is the ability of the commercial welder to spot weld from one side of the work. Moreover, this is a very fast welding method for the production of multiple spot welds with a high degree of reproducibility.

    MIG welders know that the arc spot welding can be done by using gas shielded metal arc processes and tungsten inert gas. When the multiprocess welder performs tungsten spot welding, one uses the same power supply that is required when performing regular TIG welding process. In this case however, the commercial welder requires special spot welding gun and controls. During the TIG spot

  8. How to Weld Sheet Metal With MIG and TIG

    For ages, fabricators have had a hard time welding sheet metal in an efficient and cost-productive way. They have to look at many factors such as equipment-investment vs. burn-through, weld appearance, warping, heat affected zones and more.

    However, welding sheet metal can be very efficient if they adopt the proper techniques.

    During Process Selection

    You want to prevent warping, burn-through and excessive heat zones when you decide to weld metal. All this and ensuring that your welded metal contains adequate mechanical strength for the purpose it will serve. For this you need controlled processes such as short circuit transfer GMAW, pulsed GMAW, pulsed GTAW and GTAW.

    GMAW Electrode and Shielding Gas Selection

    For this process, you need wires with the smallest diameter as feasible. They require the minimum amount of heat to melt. This prevents burn-through to a larger

  9. MIG and TIG Guidelines for Aluminum Welding

    Reproduced courtesy of the Welding Design and Fabrication Magazine  

    These are guidelines for the selection of the right equipment for welding, applying the right technique, preparation of base materials and examining the weldments visually so as to ensure high-grade gas metal and also tungsten inert gas welding on any aluminum alloy.  Welding of aluminum alloys may prove to be quite challenging for even those experienced welding steels. Due to the lesser melting point and its greater thermal conductivity, aluminum alloys are easily prone for burn-through provided welders carry out specific procedures. Besides feeding the aluminum welding wires during the process of (GMAW) gas-metal-arc welding is a test since the wire has a lesser column strength, happens to be softer than steel and is prone to get entangled in the drive’s roll. In order to get over these difficult issues, operators would find that following the thumb rules and selection of equipment guidelines giv
