Metal Inert Gas (MIG) WeldingThe metal inert gas (MIG) welding is an electric arc welding process in which a continuous solid wire electrode is heated and fed into the weld pool from a welding gun. In case of MIG welding process, inert gas such as argon, helium, etc. is used as shielding gas to protect the weld pool from the atmospheric contamination.Tungsten Inert Gas (TIG) WeldingThe tungsten inert gas (TIG) welding is also an arc welding process in which the electric arc is struck between a non-consumable tungsten electrode and the workpiece. TIG welding is also known as Gas Tungsten ... Read More
The fourth industrial revolution is influencing every element of existence. New technologies emerge at a rapid pace. 5G networks and the Internet of Things (IoT) are two buzzwords in today's society that are becoming increasingly frequently used. You've probably seen them referenced on social media. So, what exactly is 5G? What is the Internet of Things (IoT)? What do these have in common, and what are their consequences? Let's take a closer look at 5G networks and IoT with Speranza today.What is the Internet of Things?The Internet of Things is a network of physical devices that are connected via the ... Read More
Fusion WeldingThe welding process that uses heat to join (or fuse) two or more materials by heating them to their melting point is known as fusion welding. The fusion welding process may or may not require the use of filler material for welding. Examples of the fusion welding are arc welding, gas welding, resistance welding, etc.Solid State WeldingThe welding process in which two workpieces are joined under a pressure providing an intimate contact between them and at a temperature essentially below the melting point of the base materials is known as solid state welding. The materials being joined without the ... Read More
When it comes to beefing up your online security, a virtual private network is your greatest friend. It also allows you to hide sensitive information like your IP address, location, and browsing history. You won't be frightened to use public Wi-Fi at airports or hotels after utilizing VPN encryption. The only information about you that will be exposed is that you are using a VPN. Advanced VPN may even disguise itself in some circumstances. VPN blocks, for example, are frequently deployed by the government to make users' life more difficult. As a result, this functionality can be quite valuable.Your complete ... Read More
The process of heating in which a high-frequency alternating electric field or radio waves or microwave electromagnetic radiation are used to heat the dielectric materials is known as dielectric heating.Applications of Dielectric HeatingSince the dielectric heating is an expensive method of heating, therefore, it is only used where other methods of heating are not possible. Some of the applications of the dielectric heating are described as follows −Plastic IndustryThe plastic is used for making many appliances. If the pre-heating of the plastic is uniform, then the molding of plastic becomes faster and fault free. This pre-heating of the plastic is ... Read More
Induction Heating FurnaceAn electrical furnace in which the heat is produced by induction heating of metal, is called the induction heating furnace. The induction heating furnaces have the capacities range from less than 1 kg to 100 tons and are used to melt various metals like iron, copper, aluminium, etc.Vertical Core Type Induction FurnaceThe schematic diagram of the vertical core type induction furnace is shown in the figure below.The vertical core type induction furnace is also known as Ajax-Wyatt Furnace.This furnace has a vertical crucible instead of a horizontal one (as in case direct core type induction furnace) for the ...

Coated ElectrodeA coated electrode is made of a metallic wire (called core wire) coated uniformly with flux material. While fluxing, the electrode about 20 mm of its length is left bare at one end for mounting it into the electrode holder. The flux material used for coating of the electrode is a bad conductor of electricity.Coated electrodes are used these days because the flux coated on the core wire is composed of special element which protects both the arc and the weld metal that passes through range of liquid action and solidification during welding.Advantages of Coated ElectrodesThe coated electrodes are ...

We've all had to use public WIFI at some point in our lives because staying connected at all times is a need for most of us, whether it's in a hotel, airport, or even a café. Maybe it's because our mobile data has run out, or maybe it's because we can't get a signal there. Public networks are always dangerous, considering weak security and high cybersecurity attacks.Why should public wifi be avoided?Data breaches and malware infections are two of the most severe risks of using public wifi. In the first case, hackers using public wifi can intercept data you send ... Read More
The primary website of the Tor Project has been put on a list of blocked sites by Russia's media watchdog. The Seattle-based NGO replied by requesting more funding for its operations in the world's most populous country. The Tor Project proposes the creation of an anonymity network based on Pentagon-funded internet traffic routing technologies.It allows concealing their online activities from prying eyes and visiting anonymous websites that are generally blocked in some areas. The initiative prides itself on being anti-censorship. A restriction on programs that give internet privacy is the latest incident in their long-running battle against free expression. They're ...

The term "hacker" brings to mind someone who is out to cause harm to people, websites, and enterprise information systems. According to popular belief, they want to mine company data and erase or alter client information. Those types of "bad guys" do exist - the cybersecurity industry refers to them as "Black Hats" - but they aren't the only hackers out there.Who is a White Hat Hacker?A white-hat hacker is a computer security expert who tests and assesses the security of protected systems and networks. White hat hackers improve security by reporting flaws before malevolent hackers (also known as black ... Read More
