In this blog post, we will take a look at a new Laser Assisted Underwater Welding Equipment. do you know, What is laser-assisted underwater welding equipment and how does it work? Laser-assisted underwater welding is a process in which laser beams are used to heat the metal and create an arc that welds two pieces of metal together. The pros and cons of this technique will be discussed as well as how it compares to other methods such as traditional MIG welding or TIG welding.
Why the LAUW is discovered?
Laser-assisted underwater welding or LAUW has been used in the offshore oil and gas industries for decades. The technology can be applied to many different types of metals, but it’s most commonly used in joining pipelines, risers, and flowlines together.
It was developed because wet welds were susceptible to corrosion due to water exposure and laser welding eliminated this issue. the only byproduct is water vapor from cooling down parts after they’ve been welded together.
Benefits of using this type of technology for underwater welding:
This process uses lasers to weld together metal underwater with the same accuracy as traditional welding methods but without any need for an external air supply, which makes it much more efficient and practical than other underwater welding techniques.
Laser-assisted underwater welding is an environmentally friendly process with no fumes or gases emitted during the welder’s operation.
It’s also worth mentioning that this type of laser-assisted underwater welding can be applied to materials such as bronze, brass, copper, steel, and aluminum so there are many industrial applications of this breakthrough technology.
The introduction of laser-assisted underwater welding has paved the way for an increase in efficiency and productivity when it comes to industrial manufacturing processes, not only onshore but offshore too.
The benefits of using LAUW in this environment are numerous: it can be done in shallow waters without access to large vessels; These benefits make it an excellent choice for underwater welding projects around the world!
The laser light provides the necessary heat to allow the materials to fuse together easier than traditional methods of underwater welding, which can result in more efficient production time and less energy spent per hour. It also eliminates the need for helium because lasers produce their own gas-less environment so long as they are supplied with power.
Drawbacks to using this type of technology for underwater welding
LASER-assisted underwater welding is expensive.
The laser beam can be disrupted or changed by other external factors. which can cause the molten metal to solidify before it reaches the base material
Training for this process is time-consuming and requires a lot of dedication on the part of the person being trained.
It is very expensive; welding with lasers costs about $10,000 more than traditional methods.
When using lasers for welding, you need to use special equipment like helmets or protective eyewear which can cost up to $500 each time they are used.
Laser Assisted Underwater Welding Equipment
Laser assisted underwater welding process emerged as an advanced technique for those complex jobs needing underwater sheet metal welding.
The equipment has been broadly categorized as the following: heavy duty equipment and light weight portable equipment.
For a commercial diving company, it is more likely that they would use a portable system because of their mobility requirements. These systems are generally made of three parts, namely the laser beam projector, the power supply and the water jet flow nozzle. The laser beam projector will transmit a powerful infrared ray into the workplace once its trigger button is depressed by hand which directs to an area where water can be blown from a jet nozzle with high pressure creating enough force to break through any type of material by causing rapid heating of steel even in completely submerged conditions
