The Kaveri is an Indian river flowing through the states of Karnataka and Tamil Nadu. The Cauvery River rises in the Western Ghats and flows in eastwardly direction passing through the states of Karnataka, Tamil Nadu, Kerala and Pondicherry before it drains into Bay of Bengal.The total length of the river from source to its outfall into Bay of Bengal is about 800 km.The Cauvery basin extends over states of Tamil Nadu, Karnataka, Kerala and Union Territory of Puducherry draining an area of 81,155 Sq.km which is nearly 2.7% of the total geographical area of the country with a maximum length and width of about 560 km and 245 km.
Cauvery river is the largest river in tamil nadu occupying 765 km.The Kaveri is a sacred river to the people of South India and is worshipped as the Goddess Kaveriamma. The primary uses of the Kaveri is providing water for irrigation, water for household consumption and the generation of electricity.In February 2020, Tamil Nadu assembly passed bill to declare Cauvery Delta as Protected Agricultural Zone, includes Thanjavur, Thirvarur, Nagapattinam and five blocks in Cuddalore and Pudukottai. The bill fails to include Tiruchirappalli, Ariyalur and Karur which are geographically included in the Cauvery Delta.The cauvery river is the main source for the delta region for irrigation.It ends in the bay of Bengal.
On 22 June 2018, despite opposition from Karnataka, the Central government constituted the Cauvery Water Regulation Committee (CWRC) as per the provisions in the Kaveri Management Scheme laid down by the Supreme Court.
Acting on the Supreme Court’s direction, the Centre constituted a Cauvery Water Management Authority (CWMA) on 1 June 2018 to address the dispute over sharing of river water among Tamil Nadu, Karnataka, Kerala and Puducherry.The central government failed to adhere with the top court’s deadline of within six weeks of deliverance of judgement.

Metals are inorganic materials with high thermal and electrical conductivity. Metals can be rolled to form plates or sheets, or they can be cast or machined to form more complex shapes. Metals can be pure elements such as iron or chrome. Metals can also be alloys, or mixtures of two or more elements. For example, stainless steel contains both iron and chrome. Laser marking is a common application for metals. Laser cutting and engraving are also possible with sufficient laser power.
For almost any metals, fiber laser machines provide readable marks quickly and efficiently. They’re ideal for engraving all types of metal surfaces. Examples include aluminum, anodized aluminum, steel, stainless steel, magnesium, lead, and zinc.
Fiber laser machines are low maintenance, use no consumables, and create high-contrast marks. You can use them to permanently mark data matrix codes, QR codes, serial numbers, barcodes, logos, and more.
Laser engraving metals with barcodes, serial numbers, and logos are very popular marking applications on both CO2 and fiber laser systems.
Thanks to their long operational life, lack of required maintenance and relatively low cost, fiber lasers are an ideal choice for industrial marking applications. These types of lasers produce a high-contrast, permanent mark that does not affect part integrity.
When marking bare metal in a CO2 laser, a special spray (or paste) is used to treat the metal prior to engraving. The heat from the CO2 laser bonds the marking agent to the bare metal, resulting in a permanent mark. Fast and affordable, CO2 lasers can also mark other types of materials – such as woods, acrylics, natural stone, and more.The laser has been serving well for many years, particularly when it comes to laser engraving and laser marking metals. Not only soft metals, such as aluminum but steel or very hard alloys can also be marked accurately, legibly and quickly using a laser. With certain metals, such as steel alloys, it is even possible to implement corrosion-resistant markings without damaging the surface structure using annealing marking. Products made of metal are marked with lasers in a wide range of industries: The applications range from the marking of industrially produced series products for traceability to the personalization of promotional items with logos or names.
Laserbeschriftung Metall is useful for working with metals and is mostly used in the manufacturing and construction industry.
Main Processing Types
Cutting
Laser light irradiates a fixed point, usually with repetition to melt the material. The laser can easily melt through thin metals, fabrics, and leather. Because there is no contact, it does not cause a reaction with the item processed. Deformation and cracking is kept to a minimum. In addition, because it is possible to specify processing areas in extreme detail, it is possible to create localized holes or cuts in places where traditional cutting tools cannot fit.
Soldering
Laser irradiation is used to heat solder paste that then joins metals. This irradiation is highly localized allowing for extremely precise soldering compared to traditional methods. This precision also reduces the head effected zone on the parts.
Solder Barrier
Electronics continue to get smaller and thinner. As a result, connector terminals need solder barriers (nickel barriers) to stop the soldering from expanding. Conventionally, masking was used on locations where electroplating was not necessary. However, removing the mask material took time and effort. Surface layer removal using laser light is effective in these cases.
Welding
Laser welding irradiates two targets at the focal point and joins them together by melting and the soldifying the metal. It is possible to irradiate a pinpoint with high density energy and complete the process at high speeds. Material distortion due to heat is kept to a minimum. In the past, deformation occurred easily, but now even thin materials can be welded.
Suitable metals for laser marking and engraving:
Stainless Steel
Aluminum
Anodized aluminum
Hardened metals
Alloyed steels
High-speed steels
Titanium, titanium alloys
Carbides
Brass
Copper
Precious metals (e.g. silver, gold)
Coated metals
Manually Loaded Laser Marking Machines
Flex Workstation
The Flex is our simplest turnkey machine since it includes the least amount of automation, but it can be automated with minimal upgrade any time. It is ideal when a fast marking time isn’t a priority, or when part loading represents a minor portion of the total marking time.
Designed to minimize the impact of part loading on your cycle time, this machine uses a rotary table to allow multiple operations at the same time. The operator can load and unload parts, trigger table rotations, and start laser marking.
With challenging requirements, the key to prevent bottlenecks is to mark in hidden time. This machine achieves this using a rotary table. While a robot arm loads a part, another part is engraved at the same time.
Robots used for multiple operations can be leveraged by opting for an open-air design, where the robot moves parts between stations and hold them during marking. This design easily supports multiple parts and cavities.
With a flexible door machine design, markings can be positioned anywhere, and robot arms can load parts from any direction. These machines are perfect when the robot needs to perform other tasks during the marking operation.
Conveyor machines can account for all types of positioning variations that occur on conveyors. They can mark parts on the fly or while the conveyor is stopped for other processes like quality control, bundling, or weighting.
Ever wondered what will happen if all the dense forests and wildlife vanished from this world? The answer is simple. Everything will be destroyed which will be impossible to control. The heading of this article makes it very clear what this article is going to be. A meaningful quote by Anthony Douglas Williams where says, “Animals should not require our permission to live on Earth. Animals were given the right to be here long before we arrived.” This has so much value and importance because this is a very fact.
Over the years, humans have grown and are moving forward towards development, progression, industrialization, mechanization and so much more. However, during this process what we have also brought is climate change, an increase in natural disasters, deforestation, scarcity of daily requirements, and so many more problems. The things that we as living beings get from nature, people take it for undeniable grant and constantly misuse it and pollute it with toxicants whether it is air, water, or land. Imagine the time when you are taking a stroll on the beach and you let the cool seawater flow on your feet. Now, imagine the same thing with plastic, waste thrown everywhere would you be able to feel the same beauty and aura of the beautiful sea and land? Well, the answer is no. The way pollution and overconsumption by humans are in a high increase so much so that things are getting very bad not just for us but also for those living creatures who have no role to play in this devastation.
The threat of wildlife in the water
The seas, ponds, rivers, ocean everything is into pollution day by day. It has become a means of monetary value, and great economy when people are getting to see clear water and fish in it. This is the sad condition of our present times, which needs to change. Not just the water animals that we can see even animals that are deep down in the ocean are also in threatening condition by human activities. Human consumption and production are taking over nature drastically. Let us take some instances, crocodiles, and alligators, which were once common animals, are now in a threatening position because of human activities. Wondering how? Well, many companies make exotic leather out of crocodile and alligator skin. These leathers are in use for the most common accessory such as shoes. It is also commonly used for making handbags, belts, watchbands, wallets, briefcases, jackets, and furniture. Dolphins are supposedly smarter than humans are and are the most beautiful, loving, caring, amazing water mammal we can think of. We do not think twice when we are hurting this harmless mammal while making products such as coats, bags, jackets, waterproof boots and so many more products for human consumption and development. These are just some of the animals that I have put awareness out for their misuse and harm. Many more animals like fishes, sea lions, sharks, whales, corals, octopuses, crabs, squids, and pearls are constantly in use by humans for the production of not just exotic and expensive accessories and items but also for human food consumption. They are put into cultivation in various farms under extremely terrible conditions just for human consumption. I am not saying consumption of seafood is bad. However, I am only asking you to think about the need for expensive and exotic food that is manufactured every day just for the sake of high human consumption.
The threat of wildlife in the land
Words are less to speak about the extinction and pathetic condition of wildlife in the land. All animals in the land are slowly becoming extinct and endangered because of human activities. It is sad to know the kind of things people do for money. I do not even know where to start. Elephants that are considered the creators of the jungle and that hold respect and value among the animal kingdom itself are constantly killed for tusks that are in use for ornaments, and many other things. Lions the kings of the jungle are poached or are even killed just to show power among people. They are killed for their magnificent mane. Tigers, which were once on the brink of being extinct due to excessive killing and poaching, are now slowly regaining their population in the wild due to constant work of protection, awareness, funding, programs and so much more has brought about some change. It is time we start acting for the rest of the animals so that they do not go through the process again. Rhinoceros are strong well-built creatures that are in constant threat every day for their powerful horns and even their hooves. It is disheartening to see how the actions of some human beings have a grave negative consequence on other people and the ecology overall. There are many more animals I can name such as the cheetahs, leopards, jaguars, panthers, deer, snakes, and other animals that are constantly in danger for their natural gift of beauty. This is not fair for these animals because there is no fault of their yet they suffer the most
The threat of wildlife in the air
Everyone must be wondering how animal species that do not stay very close to us be in the danger. Let me give you an instance. When was the last time you saw sparrows in the city or even fireflies in the evening or colorful butterflies fluttering around early in the morning? All of this sounds like a dream or fantasy. The reason it does is that not all of the things that used to happen before happen anymore and there are several factors for it. Sparrows and common green parrots were captured and then sold as pet animals. Due to the horrible conditions, they were kept in many of these birds died. Crows that were once seen in huge numbers are in small numbers because of the increase of heat in the atmosphere and due to their black feather, they die of exhaustion and stroke. Ostriches, emus, and kiwis are birds that cannot fly are also endangered by humans and their activities. Peacocks, which are the national bird of India, are also not spared. They are killed for their beautiful feathers for human activity. These are just some of the commonly known birds that I have named. Many more birds are exotic and are rare species that have also come under the human radar that is very displeasing.
The reason I have named common wild animals that we might have seen and heard is so that people understand the importance of the problem and take some immediate action. This is necessary so that the animals that we see now do not end up just in pictures for our future generation. I am not saying that development, progress, or industrialization is wrong. However, it does become bad and questionable when other species and animals are endangered, threatened, abused, or at the close end of extinction. Many more animals that are exotic and birds need our attention. I will conclude with a thought-provoking quote that says, “This Earth is made for all beings, not just human beings.”
