Proper information on the welding process is necessary for those who wish to learn welding and also for those who wish to improvise their welding skills. Most often people are interested to begin a career in welding and some others would like to take their career to a new level. Basically welding is the process in which base metal parts are melted and joined using a filler material which has the same characteristics of the parent metal. Welding is conducted using different sources like gas flame, laser, electric beam etc.  There are different types of welders namely Arc welders, MIG welders, TIG welders and Gas welders. Among these types, TIG welding is considered as one of the most difficult type to learn and master.

TIG welding is considered as the most flexible type of welding as it can blend all conventional metals like Carbon and low alloy steels, stainless steel, nickel alloys, aluminum, magnesium, titanium, cobalt, and copper alloys. TIG welders otherwise known as the Tungsten Inert Gas Welders uses an arc which is created from non-consumable tungsten. The heat for the welding process is generated using electric current. This type of welding has many advantages like its high amperage allows welding of metals with great thickness. Other advantages include the concerns related to purity of metal and cleaning.

It is not at all an easy task to master TIG welding. Generally all the other welding methods allow the welder to simply manage with one hand. But this method requires intense attention and focus. The process involves great amount of concentration as the welders use both the hands to manage the welding area while adding the filler material to the surface. Moreover, it is highly equipment centric. For protecting the welding area from airborne contaminants, the welding uses inert gases such as argon. Due to this process, the welding would be clean and precise.

Right amount of precautions that are usually taken while performing any welding methods are always advised in TIG welding as it could be dangerous if performed carelessly. The welding brings in large intensity of light and if the eyes are directly exposed, it results in the burning of retina called as arc-eye. A face guard to shield the eye from direct exposure to intense levels of light is a must for all the welders. The whole body should be properly covered during welding as the exposed light carries UV radiation that is harmful to the skin.

TIG welding is usually used in the automobile and space craft industries since the finished materials and alloys created using the welding method are highly corrosion and cracking resistant even over a long period of time. Like all other types of welding, the TIG welding also becomes easier with practice. For a beginner, it is suggested that he must practice with scrap metal stock before attempting any real projects. This type of welding is highly sophisticated and is usually expensive than the other types as the beginners hesitate to buy the welding kit. However, the high price is worth as the product carries a number of benefits compared to any other.

Deciding to hire a contractor for pressure washing needs is a major decision. Pressure washing is not a universal cleaning method that will fix anything so careful consideration must be made when thinking about exactly what needs to be cleaned. Some common methods of pressure washing include water blasting, sand blasting, soda blasting and dry ice blasting. Dry Ice Blasting has become the most popular method of pressure washing because it is non abrasive, evaporates immediately, requires no secondary cleanup and is non-toxic.

However, even dry ice blasting can prove to be an inferior attempt to clean if the correct method is not chosen. Choosing the right dry ice blasting company is a task to be taken seriously because not every contractor will have the methods that you need to ensure the safety of your objects being cleaned.

The following items should be considered when choosing to hire a dry ice blasting company:

Credibility, equipment, products, methods and price.

The first suggestion is to ask about their certifications. If you are hiring a contractor to do your pressure washing, they should have appropriate contractors requirements for the state that they’re doing the work in. If the dry ice blasting company knows what they’re doing, they should know what requirements they need and be able to show them to you upon request. In having expertise of their trade, they should also have expertise in the products and services they offer.

Ask about what kind of dry ice they are using as well as the kinds of machines for each job. Continental Carbonic sells their dry ice by measuring it at the very last minute in order to maximize the volume of it. If your dry ice blasting company is buying an inferior product they will more than likely offer an inferior service. Also, what kinds of dry ice pellets are they using? If they are using anything larger than 1/8 inch sized pellets then they could be damaging your surface or reducing productivity (especially if you’re paying by the hour).

Dry Ice Pellets used on a high pressure blaster are excellent for removing grime, oils, mold, and weld slag. The process of blasting dry ice to these surfaces attacks the surface of the contaminant with the pellets through a hose at a high speed and breaks it apart while evaporating at the surface of the object.

However, dry ice pellet blasting is also not the universal method to cleaning surfaces. One method called Block Shaving grinds the dry ice into a finer grain like a flaky snow. This kind of blasting is ideal for thin surfaces to be cleaned and even glass. Although this method is much slower, it also is less impacting on the blast to surfaces which is good for more fragile objects being cleaned.

Most importantly, shop around- Don’t get ripped off by the first pressure washing company that you happen to come across. Consider the costs of what it would take to have a dry ice blasting contractor come and clean up your objects. If the objects being dry ice blasted are small and tough enough to withstand pressure washing, consider renting a dry ice blaster to do the work yourself. However, it might be recommended for much larger and delicate jobs to have a professional and experienced contractor take care of the work for you.

Understand the cleaning methods of the objects that you need cleaned need to be carefully considered in order to get the most of your money as well as the continued use of your equipment being cleaned.

The reason why I ask this question is because; I’m trying to broaden my scope of learning in welding. I do have an answer for myself but, I wouldn’t mind hearing some else’s information. Easy Ten Points.

Arc welding has given us a significant large major step up in the construction of metal parts. So, how precisely does it work?

The arc creates enough sustained high heat to melt the metal at the point of the arc allowing the metals to fuse. Electrodes come in 2 differing kinds. They are either consumable or non-consumable depending on if the electrode is really used up in the welding process or is able to be reused. These are just a few facts about arc welding.
The welding area is typically guarded by some form of inert gas. This is known as shielding. In the early days of arc welding, the shielding gases were oxygen and nitrogen. They tended to be crisp and porous and tended to fail. In the middle of the last century, research proved that hydrogen worked far better.

The welding industry is extraordinarily fond of the employment of initials in describing the various welding processes. MIG and TIG welding is a fine example. MIG welding means metal inactive gas welding and TIG welding is tungsten inert gas welding. Other common expressions are SAW for submerged arc welding and FCAW for flux-cored arc welding. The truth is that welding, although a particularly highly skilled craft, isn’t that hard to master. This is an important fact about arc welding because there is a dreadful deficit of qualified welders and the demand is growing every day. It was recently reported that the average age of the pro welder was a particularly high 54 years. It is easy to see that this rather old work force will be reaching retirement age in high numbers over the following a decade. This has led straight to the arc welding field being called one of the finest kept systems in the future work picture.
Due to the use of high voltage electric currents and unusually high temperatures, arc welding has traditionally been viewed as rather dangerous occupation. The risk from burns and electric shock was high in the past and the reputation was rather deserved. In fact, welding is now thought to be no more dangerous than crafts such as carpentry and plumbing.
