Tungsten inert gas TIG and metal inert gas MIG welding are the most popular gas-shielded arc-welding processes used in many industrial fields. However, improvements are needed to reduce spatter and improve weld metal toughness. Although pure argon shielding gas is desirable for weld metal toughness, MIG arcs are unstable in pure Ar to the extent that executing welding is difficult. This process has the possibility of becoming a new welding process giving high quality and efficiency.

MIG and TIG Welding

Welding is a process that has been essential to technology for many years now. From welding metal for the creation of towering skyscrapers to welding the smallest parts onto a circuit board, this process has made countless technological advances possible. However, there are many different types of welding processes used today, for different effects and needs. Arc welding is the oldest of these three welding processes. In addition, it can also be one of the most cost efficient methods. In this process, minimal materials and energy are used to complete the job, which makes it easier and faster to perform.

In every arc welding process, an electric arc is constituted between the electrode and the conductive base metals. This arc supplies necessary heat to fuse the faying surfaces of the base plates. There are several arc welding processes, namely, manual metal arc welding, gas metal arc welding, gas tungsten arc welding, flux core arc welding, submerged arc welding, etc. Each process has unique characteristics and offers several benefits compared to others. The gas metal arc welding GMAW process employs a consumable wire electrode to supply filler metal into the welding zone. This wire electrode is wrapped in a wire-pool and is continuously fed to the welding zone with the help of an automatic arrangement.

Depending on the part and production specifications, industry professionals employ different welding techniques to create the desired assemblies. The following blog post provides a comparison between the two, outlining what they entail, advantages and disadvantages, materials utilized, and typical industrial applications. Numerous techniques and technologies have been developed to optimize the welding process for different materials and products, including:. Despite similarities between the two processes, they remain distinct in their benefits and best use cases. It uses a non-consumable tungsten electrode to heat the metal and can be used with or without a filler.

Written with the support of specialists and including widescreen videos the tutorial fills in the gaps. Mig works on same principle of TIG or arc welding. Any dirt or debris must be brushed off before you start welding. Extensive Range of Welding Supplies. The best welders are quite fussy about surface preparation, and cleaning the base metal is a good habit to get into.

MIG, TIG, or Arc? How to Determine Which Kind of Welding Process to Use for the Job

It is always striking to see a near-perfect TIG weld on a finished product. A near-perfect TIG weld looks like a stack of dimes. The evenness and accuracy of the weld bead is an indicator of the skill level of the welder. Nevertheless, a near-perfect MIG weld on a consumer product such as a truck frame shows the efficiency and strength which can be achieved with MIG welding. The more you grasp the better you can choose the technology which best suits your application.

This is a basic guide on how to weld using a metal inert gas MIG welder. MIG welding is the awesome process of using electricity to melt and join pieces of metal together. MIG welding is sometimes referred to as the "hot glue gun" of the welding world and is generally regarded as one of the easiest type of welding to learn. Think of this Instructable as a guide to get you started MIG welding.

The output responses such as bead width, reinforcement, penetration, melted area, and convexity angles were evaluated. Macrographs were performed to measure the geometrical parameters of the weld bead. The results of these measurements were evaluated by a variance analysis. It was also noticed that the insertion of TIG current caused the tendency to greater wettability, penetration, melted area, width, and smaller reinforcements of weld beads. The search for improvements in productive capacity, resource utilization, product quality, reduction of production costs, among others is encouraging the research progress related to the improvement of welding processes.

Mechanical Engineering Related Differences

While MIG and TIG welding both form the weld using an electric arc, the techniques are quite different, and choosing the wrong one can lead to more than one headache. Read on for the reasons you may want to choose MIG welding vs. TIG welding. The difference between the two is the way the arc is used. MIG metal inert gas welding uses a feed wire that constantly moves through the gun to create the spark, then melts to form the weld. TIG tungsten inert gas welding uses long rods to fuse two metals directly together.

January 6, Robotic Manufacturing , Welding. Robotic technologies are being used more and more in manufacturing plants small and large, and even in project-based workshops. Robotic welding is a costly investment, but it also starts to improve the bottom line of your business performance from the first day you begin operating it. Two of the most common welding technologies used in factories across the U. Here are four key benefits for you to take advantage of when you use robotic welding.
