Summary:

Overall this article goes through the main topics when getting started on Gas Tungsten Arc Welding. From what is required such as shielding gas to how to get set up machine wise.

Reflection:

The article firstly provides a brief overall description of what it is such as how using shielding gas protects the weld pool. The following topic is what type of power source is necessary depending of what welding application will be done. For example aluminum will require alternating current but other metals will work with direct current. The reader is then provided with what type of non consumable electrodes will be needed and how to prepare them. Lastly shielding gas is also a very key part because without such welding process wouldn’t be possible. Many different mixtures are listed with each having information of what their main purpose would be.

Summary:

This article provides a very detailed history about how it all began. It also provides the reader with the necessary information to understand how this welding process developed over the years.

Reflection:

The article quickly provides the year GTAW was firstly introduced by the creator known as Russell Meredith. It goes on to state that the main reason for this new welding process is because before it many metals couldn’t be welded with other methods. To this day GTAW is widely used to join different metals together and the full control a welder have over it allows for many projects to be done as desired.

This article comes directly from Miller a well known company within the welding community. They make welders and provide other necessary equipment. Being able to read tips directly from them will be far more beneficial as they know everything. The articles goes into details such as angles to use and other small details.

Reflection:

I have personally used this article and put these techniques into practice. On of the main issues for starting welders is the angle they do when traveling. The articles provided images to better understand how certain angles can make a big difference. They also provide tips such as getting as comfortable as possible and doing dry runs to see if you will actually reach the end of the weld or if you will need to re position yourself.

Summary:

In this article it clearly states both the good and bad of GTAW. This is important so people can have a clear understanding if this is something they would want to use for their applications or not.

Reflection:

This articles provides the main benefits such as high quality and clean welds achievable with such processes. Although it states that the disadvantages would be the high cost to operate these welding machines. It also takes quite a while to become fully familiar with GTAW. Overall the article allows us to understand that there is always a cost for a highly beneficial welding process.

Summary:

Aerospace plays a big role in our daily lives but it can only be achieved when these manufacturing companies select GTAW to build airplanes. The article explains why GTAW is selected over other processes and how they benefit from it.

Reflection:

The main idea in this article is that high quality welds is the most important requirement in aerospace. When manufacturing airplanes people have to follow a certain code in order for everything to come out correct. For that reason they detail how the ability to weld different metals together is highly beneficial in the aerospace industry.

Summary:

In this article basic information such as different weld joints created when two metals are put together are described. A brief description of how a weld joint is used is also provided.

Reflection:

Once again this is one of the articles that provides lots of knowledges for upcoming welders. Knowing how and why a weld joint will be used is highly beneficial to gain the proper experience. Knowing how each joint also has its own different combinations can be confusing at first but it is highly important in order to apply it at a job site.

This article talks about the future of GTAW in robotics. Within the articles people make the statement that having a robot do GTAW isn’t the brightest idea someone can have.

Reflection:

This article is very important because many people have a fear that robots could possibly take their jobs. Although that isn’t the case for GTAW welding process because it doesn’t seem to be as effective as a human welder. As stated in other articles GTAW requires lots of skill and experience. If a robot makes a mistake when doing production welding then they wouldn’t notice. For that reason the article explains and provides examples as to why GTAW is one of the welding processes not being picked to be used by a robot.

Safety is a key aspect of welding for that reason this article states the dangers and how to prevent them in job site. From what shade of darkness to gas related risk are all important considerations when GTAW.

Reflection:

This article should be read by everyone interested in welding in order to be properly informed of all dangers. Picking out the correct darkness level is highly important in order to protect your eyes. As stated in the article, the higher the welding amps the higher your level of darkness should go. Another key risk mentioned is not having proper ventilation. Whether at school or at a job site proper ventilation should always be applied in order to protect yourself and others from welding fumes.
