In the absence of ready-made electrodes, they can be made independently. Recommendations for self-manufacturing of electrodes are given in the literature.

To do this, you must have a soft low-carbon wire with a diameter of 2 to 6 mm. First, it must be straightened and cut into pieces 300-400 mm long. After that, a protective coating is prepared in the bank or simply a coating of the one shown in Table. 18.6 composition.

How to make welding electrodes

The specified amount of coating is enough for 100-200 electrodes.

The cut pieces of wire are immersed in the coating so that one end remains uncoated with the coating by approximately 20 mm (for clamping into the electrode holder).

Then the coated electrodes must be dried at a temperature of 20-30 ° C, after which they can be used for welding both on alternating and direct current.

Homemade electrodes can only be considered as a temporary alternative to industrially produced electrodes. Of course, these electrodes cannot be used for welding critical structures.

Air trap for insects 01.05.2024

Agriculture is one of the key sectors of the economy, and pest control is an integral part of this process. A team of scientists from the Indian Council of Agricultural Research-Central Potato Research Institute (ICAR-CPRI), Shimla, has come up with an innovative solution to this problem - a wind-powered insect air trap. This device addresses the shortcomings of traditional pest control methods by providing real-time insect population data. The trap is powered entirely by wind energy, making it an environmentally friendly solution that requires no power. Its unique design allows monitoring of both harmful and beneficial insects, providing a complete overview of the population in any agricultural area. “By assessing target pests at the right time, we can take necessary measures to control both pests and diseases,” says Kapil ... >>

The threat of space debris to the Earth's magnetic field 01.05.2024

More and more often we hear about an increase in the amount of space debris surrounding our planet. However, it is not only active satellites and spacecraft that contribute to this problem, but also debris from old missions. The growing number of satellites launched by companies like SpaceX creates not only opportunities for the development of the Internet, but also serious threats to space security. Experts are now turning their attention to the potential implications for the Earth's magnetic field. Dr. Jonathan McDowell of the Harvard-Smithsonian Center for Astrophysics emphasizes that companies are rapidly deploying satellite constellations, and the number of satellites could grow to 100 in the next decade. The rapid development of these cosmic armadas of satellites can lead to contamination of the Earth's plasma environment with dangerous debris and a threat to the stability of the magnetosphere. Metal debris from used rockets can disrupt the ionosphere and magnetosphere. Both of these systems play a key role in protecting the atmosphere and maintaining ... >>

Solidification of bulk substances 30.04.2024

There are quite a few mysteries in the world of science, and one of them is the strange behavior of bulk materials. They may behave like a solid but suddenly turn into a flowing liquid. This phenomenon has attracted the attention of many researchers, and we may finally be getting closer to solving this mystery. Imagine sand in an hourglass. It usually flows freely, but in some cases its particles begin to get stuck, turning from a liquid to a solid. This transition has important implications for many areas, from drug production to construction. Researchers from the USA have attempted to describe this phenomenon and come closer to understanding it. In the study, the scientists conducted simulations in the laboratory using data from bags of polystyrene beads. They found that the vibrations within these sets had specific frequencies, meaning that only certain types of vibrations could travel through the material. Received ... >>

Vodka from water and air 08.11.2019

New York Air Co. developed a recipe for vodka, consisting only of water and air. No grains, no yeast, just electricity.

The company turns carbon from air into pure ethanol by electrically splitting water into hydrogen and oxygen. The carbon, oxygen and hydrogen atoms then recombine to form "environmentally friendly" ethanol.

"The process is similar to photosynthesis, but more efficient," explains Air Co. CTO. Stafford Sheehan.

The technology of the Americans simplifies the production of vodka and at the same time cleans the air, taking carbon from the external environment. The company calculated that one bottle of vodka purifies the air like seven large trees. In other words, each bottle removes half a kilo of carbon dioxide, writes CNBC.

Air Co.'s air recycling machine takes up little space and is powered by solar energy. The only by-product in production is oxygen. Unlike other vodka companies, Air Co. no need for giant fields for grain.

The only negative for consumers may be the price - $ 65 per bottle. At first, it will be sold only in some bars and restaurants in New York, and in 2020 it will reach retailers. CNBC representatives tried Air Co. - they say, vodka is like vodka. The taste is indistinguishable from the usual.

However, on one Air Co. will not stop. The company is going to produce perfumes and cleaning products for the home, adding to them ethanol produced using electricity.
