Argomento e obiettivi del testo
 It Works! è un corso di inglese tecnico per gli studenti dei corsi con indirizzo Elettronica, Elettrotecnica e Meccanica, con focus sulla Manutenzione e Assistenza Tecnica.
 
 I contenuti, veicolati attraverso testi di livelli di diversa complessità, vengono esplorati utilizzando le quattro abilità in modo omogeneo ed integrato. Il testo dà inoltre grande importanza alla pratica linguistica attraverso attività che agevolano la revisione e la ripetizione dei contenuti studiati, favorendone l'apprendimento e l'interiorizzazione.
 I brani offrono un assortimento di stili, registri e livelli di difficoltà, e sono tratti da fonti diverse ed autentiche: libri e manuali, riviste e quotidiani online e siti web, anche specialistici.
 
 Il testo si propone di:
 
 <ul><li>far acquisire le competenze necessarie per comprendere testi che presentano termini, espressioni, strutture sintattiche e modalità discorsive specifiche del linguaggio settoriale;
</li><li>migliorare le capacità di ricezione e produzione orale e scritta;
</li><li>consolidare abitudini grammaticali corrette;
</li><li>incoraggiare l'autonomia linguistica e la soluzione di problemi;
</li><li>stimolare l'interesse e la partecipazione attiva degli studenti, dando spazio alla loro esperienza personale e a problematiche di attualità.
</li></ul>La struttura
 It Works! è diviso in cinque Moduli, ognuno dei quali ripartito in un numero variabile di Unità.
 Ogni Unità è suddivisa in brevi Capitoli su due pagine – teoria ed esercizi – per favorire sia uno studio più parcellizzato, sia la scelta antologica da parte dell'insegnante.
 
 Brevi link (curiosità, ampliamenti, rimandi, attività o mini-approfondimenti) arricchiscono i brani per consentire una maggiore interattività. Il primo esercizio di ogni capitolo è sempre una mappa riepilogativa da completare che aiuta a focalizzarsi sulle key words e i contenuti chiavi del testo proposto.
 Un ricco apparato iconografico, infine, accompagna i brani di lettura, per ognuno dei quali è previsto un esauriente glossario.
 
 Ogni Unità si conclude con tre sezioni:
 
 <ul><li>Vocabulary and Praseology: attività di revisione e consolidamento del lessico;
</li><li>Case study: argomento di attualità corredato di esercizi mirati all'approfondimento e alla discussione;
</li><li>Mapping your Mind: mappa riepilogativa per rappresentare la rete di relazioni tra i vari argomenti delle unità e a fissare le key words.
</li></ul>Alla fine di ogni Modulo, il testo propone ulteriori attività:
 
 <ul><li>Real-Life skills: compiti di realtà reali e collaborativi, con un taglio di tipo pratico calato nella realtà;
</li><li>Clip: brevi filmati tratti da opere cinematografiche.
</li></ul>Contenuti digitali integrativi

SECTION 4 – MECHANICS

87 How many types of steel do you know of? It can weld a wide range of metals, including stainless steel, titanium, aluminium, and nickel alloys and enables high-quality welds with minimal distortion. Soldering is mainly used in electronics, but also in plumbing and metalworking. JOINING Joining methods are key technologies in many manufacturing industries: a large number of processes are used to assemble individual parts into a larger, more complex component or assembly. Joining processes include welding, brazing, soldering, and adhesive bonding.   Welding Welding is used to join metals or thermoplastics by using high heat to fuse parts together. There are different types of welding. The most common are:   Fusion welding, which can be:   Autogenous, when similar material combinations or materials belonging to the same family (e.g. two types of stainless steel ) are joined. The weld is made by melting the edges of the two workpieces and allowing them to fuse together; Fusion welding   Dissimilar, when materials with different alloys (e.g. carbon steel and stainless steel) are joined. The weld is obtained by adding extra material during the process through the melting of a filler rod or filler wire; ONLINE RESOURCES   Adhesives brazing: brasatura edge: margine, bordo soldering: saldatura tenera welding: saldatura 206 MECHANICS   Electric arc welding, which uses electricity to produce the intense heat necessary for welding. Some electric arc processes use a consumable welding electrode that melts and becomes part of the weld metal;   Laser beam welding, which is a process in which two metal pieces are joined together by the use of a laser: Laser beam welding the laser beam arc focuses on the cavity between the two metal pieces producing heat that melts the material and fills it. After cooling, a strong weld is formed between the two pieces.   Plasma welding is a method that produces a plasma arc between the electrode and the material. The resulting high heat concentration enables precise high-speed welding.   Brazing, soldering, and adhesive bonding   Brazing is a joining process in which two or more metal parts are bonded together by melting a filler metal that flows into the joint. The filler metal has a melting point above 450°C but below the melting point of the base metals.   Soldering is similar to brazing but uses a filler metal with a melting point below 450°C. It is primarily used for electronic connections and delicate components .   Adhesive bonding is a process where two metal surfaces are joined using a layer of adhesive material. This technique relies on the adhesive s ability to form strong chemical or physical bonds with the metal surfaces. Soldering

Inert Gas Welding Inert Gas Welding refers to welding processes that use inert gases as a shielding medium to protect the weld spot from atmospheric contamination. There are two types of gas welding:   MIG (Metal Inert Gas) is a process that uses a consumable wire electrode fed continuously through a welding gun. The arc melts the wire and base metal, creating the weld. An inert or semi-inert gas (like CO2 or a mix of argon and CO2) shields the weld from contamination, for this reason it is rarely used outdoors where the air is unstable because of wind. It can be used on Type Electrode Gas   Materials stainless steel, mild steel, aluminium, and plastic and it is suitable for thicker materials and highproduction environments. TIG (Tungsten Inert Gas) is a welding process that uses a non-consumable tungsten electrode to create the weld. The arc is protected by an inert gas, typically argon or helium, to prevent contamination. It requires a filler rod for thicker materials, but it can also weld without filler metal. It produces high-quality, precise welds and is used to weld copper, titanium, steel, aluminium, and even two different metals.
