They are widely used in short-distance transport, but to operate them, it is necessary to have appropriate qualifications - mobile platforms are lifting devices designed for lifting materials and people. They are used primarily during construction and assembly works carried out at heights, both inside and outside buildings. All mobile platforms are subject to supervisionRead more "
Appropriate preparation is needed to conduct welding work - only a properly trained and authorized person is able to find a job as a welder. The Ordinance of the Minister of Economy of 27 April 2000 on occupational health and safety during welding works (Journal of Laws No. 40, item 470) indicates that welding works should beRead more "
Welded joints are formed by local melting and solidification of elements with the addition of a binder. Depending on the method and the joint, different types of welds are distinguished. We present their list. Types of welds: butt welds - occur in butt joints and angular joints, they are formed between the wall of a given element, which forms its thickness, and the other element, they can also includeRead more "
MIG / MAG welding (Metal Inert Gas / Metal Active Gas) is one of the most commonly used methods of welding materials. It uses consumable electrodes shielded by inert gases for the MIG 131 method or active for the MAG 135 method. The inert shielding gases used in this method are primarily helium or argon, whileRead more "
Various methods are used to connect metal and other elements by welding. Below we present the most popular and less used. 311-G gas welding - one of the most commonly used welding methods, which involves the use of acetylene. The materials are joined at a temperature of 3,100 degrees Celsius. Gas welding is most often used duringRead more "
Welding consists in local melting and solidification of materials. Welded joints are mainly related to joining metals, mainly steel, but also plastics. During welding, an additional welding filler is used, which melts with the base material and fills the weld. Currently, various welding methods are used - the most popular ones are gas welding and weldingRead more "
Welding machines are devices used in the process of welding together elements made of metal or plastic. To operate them, it is necessary to have the appropriate welding qualifications, therefore people who want to work as a welding machine operator must take part in the appropriate course. Welding qualifications are granted in the following categories: butt welding with a heating elementRead more "
One of the most popular welding methods is resistance electric welding, which is also referred to as resistance welding. This process involves joining metal elements together on the basis of their natural properties - electrical resistance. Two elements can connect with each other because heat is released in the metal under the influence of current, as well as the pressure of the electrodes,Read more "
Welding is one of the basic technologies used to permanently join elements together, in particular parts of devices and structures made of metals or plastics. Glass-to-metal welding is also used. The welding process consists in heating the surfaces in contact with each other in such a way that they can obtain a plastic state, otherwiseRead more "
