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.

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.
