The sometimes over looked disadvantages of TIG Welding are its low speed and deposition rate which utilizes hot or cold wire feed and high heat input efficiency. By using shielding gas, these problems can be overcome. The TIG weld zone is also difficult

Tungsten inert gas (TIG) welding is the process of blending together reactive metals such as magnesium and aluminum. The TIG welding method became popular and useful in the early 1940s and, as a result, has greatly propelled the use of aluminum for welding and structural processes. TIG welding is commonly used for both high quality and manual welding.

The temperature requirement for forge welding is upto 90 percent of the melting temperature of individual metals. Steel has a lower temperature requirement than iron. The metal may have a shining or wet finish at the welding temperature. Care must be taken to avoid overheating of the metal to the point

Welding is the process of joining pieces of metal or other parts by heating the surfaces to the point of melting using a blow torch, electric arc, or other means. This careers demand has skyrocketed in recent years. According to Tri-County Technical College, welding is ranked as one of the top ten fastest growing career fields in South Carolina by the US Department of Labor (“Welding Associate's Degree”). Welding is a very meticulous career, to be a welder you have to be focused, careful and you have to have an extensive knowledge of the field to be successful. Welding requires a variety of skill sets. If a person has a variety of skills and experience doors will open up for positions such as: shipbuilding, automotive repair, and construction.

Gas metal arc welding was originally made for weld materials such as aluminum, copper, brass, tin and lead. It was also used on steels, but shielding gases were highly expensive in the early 1900s limiting GMAW’s use on steel. It wasn’t till the mid 1900’s for GMAW to really take off. There were many different variations of arc-length, electrode size, and power supply units. Since the MIG welder is so versatile, there are many different types of things to make this piece of equipment.

To become a welder you need to know a lot , different rods, different types of welding to learn all this you need the right training , there are many technical schools and colleges where you can go to find out the basics of welding. there are many types of welding one of the biggest is stick welding there is also flux core, tig, mig. on the pipeline there is a lot of

If you want to be a welder, and actually have a career, you can go to a welding school and learn how to weld, or you can try to be a welders helper and just learn the trade. Welding can be a tough job if you don’t know what you are doing or you do not enjoy doing it. Welding is a fabrication or sculptural process that joins materials together (Modern Welding). This is the process that uses fuel gases and oxygen to make a molten pool of metal to fuse together two pieces of metal, called puddeling (oxy-fuel welding and cutting. Wikipedia). If you decide to weld as your profession, most welding school students have little trouble finding jobs and finding people certified to weld correctly (Welding.Wikipedia).

I watched Home Made Tig Welder. In the video he talks about how to turn an A/C stick welder into a crude tig welder using a buz box. The video was a bit confusing to me because i dont know much about tig. He does talk about how he sets his welder up with argon and how he connects his electrode holder onto his tig torch. He talks about scratch starting and how difficult it is to control the weld.

If you are welding in a position that is 45 degrees or steeper, you will be fighting gravity. The 7018 electrode was made specifically for this purpose. It is consider the perfect choice for vertical or overhead because of the low iron powder content. 7018 makes a weld puddle that almost instantly and won't drip off while working. If you need to overcome poor surface

In the process analysis of resistance spot welding on galvanized steel used in vehicle body manufacturing, the quality of spot weld is checked from the tensile strength and shear strength properties of the spot weld. The four important parameters in this analysis are:

Welding is a common practise in today’s society where it allows us to join, and construct metal objects that we can use for contraptions and devices in common places where people live, work and interact with others. There are many ways that somebody can “weld”, but we are specifically looking at the gas “Acetylene”, and how it is used, and needed today.

When the LB incident power increases, the absorption of heat by the aluminium plate also increases, this in turn increases the vaporization of volatile elements in LB welds. The reduction of magnesium plays an important role in reducing the yield stress of the welded joint as shown by Fig.2.1. Approximate reduction in annealed condition of the alloy is around 10 ~ 15 MPa. The base metal, which has been used in this study, is in strain-hardened condition and the reduction of yield stress might be more than 15

 Parametric Optimization of Gas metal arc welding process by PCA based Taguchi method on Austenitic Stainless Steel AISI 316L

FSW is a relatively new welding process for bonding metals in solid state and uses a non consumable tool for this purpose. It is a solid state process which means coalescence takes place much below the melting point of the metals.

Martensitic stainless steels have good mechanical strength and moderate corrosion resistant. Because of their excellent corrosion resistance and mechanical strength, martensitic stainless steels are used for manufacturing the steam turbine blades, heat exchangers, automotive components and structures, petrochemical & process piping. Properties of martensitic stainless steel can be changed by the heat treatment. Increasing productivity of any welding process while maintaining or even improving the weld quality has been the task of researchers in the field of development of welding processes. Over the years welding methods and techniques have developed to great extent [3]. Now it is feasible to weld starting from thin metal
