Layering A Weld: Why It’s So Important

Welding, as we know, is the use of heat to melt a base material and join it with another. The number of passes and the ideal positions for the torch in its own layer are made while going unto the next layer. When it comes to welding, being able to do multiple layers is sometimes required especially if the metal is very thick or if maximum ductility of steel is needed. This can be done through the process of compiling or putting a filler metal in consecutive passes until the joint is filled. Controlling a small puddle is easier while avoiding oxides, having an incomplete infusion, and inclusions with the metal. This method is more of having a buildup sequence. The welding torch is controlled by the Y-axis to keep the arc voltage or current constant during the welding process and at the same time cause the welding torch to oscillate along the X-axis in the slot.

In simple terms, layering a weld is when multiple weld passes form a layer by compiling them in until they are filled into the weld. So basically, it’s just compiling or building up new layers by depositing them on top of the previous layer. While doing this, you should keep in mind the importance of monitoring or checking the welding deformation for the previous layer.

Welding conforms with the specific type of materials or what does it need to achieve. Multi-layer welding can give benefits over fusion when it comes to those thick plates. It is used for great durability and can also be called for making structures or forging new things. It takes a long process of stacking which needs you to have a lot of patience and endurance. Time and effort are needed to understand the deformation. Multilayer welding is usually done during fabrication or under compressive loading which can make geometrical imperfection to buckling. In making a lot of layers you can strengthen the material’s grip making it more durable which can produce high-quality results. In order not to make it messy, a consistent examination must be made. It’s important to note that layering a weld is important because it is meant for materials that are quite difficult to join or those that need to be thoroughly secured. Being a welder, it is essential to make a precise decision and look through the details to avoid potential defects in the project. In doing so, having broad experience is needed.

How Do They Build Huge Cruise Ships? Welders Are Essential

Welding can be a lucrative career path for skilled workers who want to make huge paychecks. All it takes is finding the right industry where you can put your trade into good use. Although there are plenty of industries that need welding expertise, shipbuilding is probably one of the best career options for welders.

Welding processes are required in the successful construction of ships for commercial and military usage. Careful, expert welding is performed on joints that are designed to prevent water and oil leaks.  And while riveting is also an option in shipbuilding, welding is more cost-effective and requires fewer materials.  

Common Welding Methods in Shipbuilding

The most common welding methods used in the shipping industry are metal inert gas (MIG) and tungsten inert gas (TIG) welding. But how are they different?

The major difference between MIG and TIG welding lies in the use of the electric arc. On one hand, MIG welding ignites spark with the use of a feed wire that is moving through the welding gun in order to melt the electrode and the metal base together and create the weld. On the other hand, TIG makes use of long rods to directly join two metal pieces.

There are also striking differences when it comes to materials that can be welded using the two welding methods and the speed of the welding process. TIG welding is generally performed on thin sections while MIG is commonly used when welding thicker structural pieces. Additionally, TIG is often used when attention to detail is necessary while MIG is used when high production rate is required. 

Welding Jobs in the Shipbuilding Industry

There are various jobs in shipyards that will need your expertise in welding, such as structural welding, pipe welding, pipefitting, and shipfitting. The job descriptions for these positions may vary from one another but they share a common denominator- welding skills.

To land a welding job in the shipping industry, you have to possess the necessary skills and techniques required to undertake the complex and specialized nature of welding works in shipyards. To do this, you should undergo technical trainings on different welding methods, especially those that are commonly employed in shipbuilding.  You can find plenty of welding training programs online that will help you prepare for your application as a welder in a major shipyard for a chance to make comfortable income and enjoy a lucrative career in welding.

But they are not the things you should look for when buying an arc welding table. The thing you should focus on in this specific type of welding table is its foldability.

In addition, there are various different forms of welding, including gas, arc, and laser welding. Arc welding is a method in which electricity is utilized to melt any material that will be utilized. Gas welding, also known as oxy-fuel welding, is a type of welding that uses a high-temperature flame. Finally, laser welders use a high-energy beam to fuse materials together. It’s a costly system that demands expert administration and dexterity.

In this part, the main focus is the Arc Welding table, on its use, purpose, and key feature/attributes. The Cherokee Observer blog points out that arc welding table is created between a metal as a base and a wire that produce an electrical current that melts the materials and fuse them together. In addition, a direct or alternating current can be used, and consumable or non-consumable electrodes coated in flux can be used. Arc welding can reach temperatures of up to 6,500 degrees Fahrenheit.

The Cherokee Observer blog points out that the key feature that you should for when you want to buy an arc welding table is its foldability or the ability to change into various positions. As the welder may need assistance for its measurements and they need to change it to different forms, the arc welding table is the best table for those kinds of activities.

Lasers Are Used In Almost Every Industry Now – Including Welding

Many people are not entirely familiar with what lasers are and how they truly work. Lasers are popularly identified with those tiny red lights that children like to play with. But in reality, lasers are a lot more useful, especially in manufacturing industries.

The laser, which stands for Light Amplification by Stimulated Emission of Radiation, is an advanced tool commonly used by industrial entities for various reasons. It can be used for cutting through metals and other materials with high precision, marking codes, cleaning, measuring speed and range, and other purposes. In fact, there are so many industrial procedures that greatly benefit from laser technology.

Benefits of Lasers in Welding

One of the industrial processes that have great use for lasers is welding.  With the advent of the laser technology, welding processes have become is more effective and efficient as it allows for greater precision and control over the welded material and yields cleaner, smoother results.

  • Faster and more flexible manufacturing process

One of the most obvious contributions of laser technology in welding is that is makes the process faster and the dynamics more flexible. On one hand, meters of thin section materials can be easily welded in a couple of minutes with the use of a high-powered laser while on the other hand, it allows for the welding of thick section materials with only a single pass, making the process significantly easier and faster. And since laser is mostly automated, remotely manipulating the laser beams with multi-axis robotic delivery systems, it allows for a more flexible production.

  • High aspect ratio welding

With laser welding, it has become possible to undertake deeper and narrower welding processes that are otherwise impossible with other techniques. In fact, joint configuration is a viable procedure with the use of lasers.

  • Lesser thermal damage and material distortion

Because laser only emits limited, highly concentrated heat into the welded material, it results in lesser thermal damage and zones impacted. Because of this, there is only minimal distortion of properties in the parent material compared to when other welding techniques are used.

The laser technology has introduced more elaborate techniques to many industrial processes. In particular, lasers have allowed welding processes to become faster, smoother, and more flexible. If you are into welding works, it is highly advantageous to take up some training courses on laser welding techniques to make your resume more appealing to potential employers in the industrial sector.

The Difference Between Pipefitters And Welders

In some countries, degree holders make the big bucks. But in many others, skilled workers are paid much more. If you happen to be in one of those latter countries, you should know that pipefitters and welders top the list. These two skill trades are often thought to be the same, but they’re not. As a matter of fact, they differ in many ways.

How do pipefitters and welders differ from each other?

You can say that welders have wider functions compared to pipefitters as while they can also at times weld some pipes, they also deal with other types of work. Actually, a welder weld just about everything under the sun, though they need special accessories for those not so common materials.

A pipefitter on the other hand, might also have a skill in welding, but one can still do his job even if he does not know this craft. Yes, and that is mainly because a person in this skill primarily focus on tasks that are related to pipes like laying and threading.

Both skill trades though need to know if a bond is made during their tasks. They might use different processes, still their goal is to combine both materials together. Usually, a welder will fuse together metals while a pipefitter will use pipes.

These two skill trades are quite in demand these days. If you happen to be a pro in any of this, you can be assured that you will get a job. Especially these days where most companies are competing with each other, and thus they usually have so many projects to deal with, a welder and a pipefitter will always be needed.

That is right and this is why it is best to at least master any of these skills. If you can do both, then why not! But, if you think that you would rather be expert in one than just ordinary in both, that is also a good idea.

Yes, a welder and a pipefitter differ with each other in a lot of ways. They might have similarities, but they are not the same positions and while you are learning, in time you will fully understand why.
