Abstract Izrada zavara MIG postupkom (Metal Inert Gas) predstavlja ključnu tehniku u zavarivačkoj industriji zbog svoje svestranosti i učinkovitosti. Ovaj postupak koristi inertni plin, poput argona ili mješavine argona i CO2, za zaštitu zavarivačkog zrna od atmosferskih utjecaja, čime se osigurava visoka kvaliteta i čvrstoća zavara. Proces uključuje nekoliko ključnih koraka, uključujući pripremu materijala, postavljanje opreme i kontrolu parametara zavarivanja. Prvi korak u izradi zavara MIG postupkom je priprema materijala, koja uključuje čišćenje površina od hrđe, prljavštine i masnoće kako bi se omogućio dobar kontakt između elektroda i materijala. Nakon toga, odabir i podešavanje opreme, uključujući zavarivački aparat, elektroda i plinski sustav, bitni su za uspješno izvođenje zavarivanja. Postavljanje tehnike zavarivanja zahtijeva pravilno podešavanje napona, brzine dodavanja žice i temperature, uzimajući u obzir vrstu materijala i specifikacije projekta. Kontrola ovih parametara omogućava postizanje željenih rezultata, minimizirajući rizik od defekata kao što su pukotine i pore. Inspekcija i kontrola kvalitete zavara ključni su za osiguranje dugovječnosti i funkcionalnosti zavara. Korištenje metoda poput vizualne inspekcije, ultrazvuka i rendgenskog ispitivanja pomaže u identifikaciji i korekciji eventualnih nedostataka, čime se osigurava da zavar ispunjava sve tehničke i sigurnosne zahtjeve.
Abstract (english) The process of creating welds using the MIG (Metal Inert Gas) method is a fundamental technique in the welding industry due to its versatility and efficiency. This method employs an inert gas, such as argon or a mixture of argon and CO2, to protect the weld pool from atmospheric contamination, ensuring high quality and strength of the weld. The process involves several critical steps, including material preparation, equipment setup, and control of welding parameters. The first step in MIG welding is material preparation, which includes cleaning surfaces of rust, dirt, and grease to ensure good contact between the electrode and the material. Following this, selecting and configuring the equipment, including the welding machine, electrode, and gas system, is crucial for successful welding. Setting the welding technique requires proper adjustment of voltage, wire feed speed, and temperature, considering the type of material and project specifications. Controlling these parameters helps achieve the desired results while minimizing the risk of defects such as cracks and porosity. Inspection and quality control of the welds are essential to ensure the durability and functionality of the weld. Utilizing methods like visual inspection, ultrasonic testing, and X-ray examination helps identify and correct any potential defects, ensuring that the weld meets all technical and safety standards.
