Shearing, water jet and plasma-cut processes were used to cut sheets, subsequently welded using ER5356 and ER4043 filler metals for TIG and MIG, respectively. Mechanical properties of the obtained sheets were assessed through tensile tests obtaining a relation between sheet preparation and welding tightness. Micro-hardness measures were performed to evaluate the effects of both welding and cutting processes on the micro-hardness of the alloy, highlighting that TIG welding gives rise to inhomogeneous micro-hardness behaviour. After tensile tests, surface fractures were observed employing scanning electron microscopy to highlight the relation between tensile properties and edge preparations. Fractures show severe oxidation in the water jet cut specimens, ductile fractures and gas porosities.<\/jats:p>","DOI":"10.3390\/ma15020412","type":"journal-article","created":{"date-parts":[[2022,1,7]],"date-time":"2022-01-07T01:14:02Z","timestamp":1641518042000},"page":"412","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":4,"title":["MIG and TIG Joining of AA1070 Aluminium Sheets with Different Surface Preparations"],"prefix":"10.3390","volume":"15","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-7610-5197","authenticated-orcid":false,"given":"Elisa","family":"Fracchia","sequence":"first","affiliation":[{"name":"Department of Management and Production Engineering (DIGEP), Polytechnic of Turin, Corso Duca degli Abruzzi 24, 10129 Torino, Italy"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-3462-3148","authenticated-orcid":false,"given":"Jana","family":"Bidulsk\u00e1","sequence":"additional","affiliation":[{"name":"EPMA PM R&D Centre, Faculty of Materials, Metallurgy and Recycling, Technical University of Kosice, Park Komenskeho 10, 040 01 Kosice, Slovakia"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-8716-7844","authenticated-orcid":false,"given":"R\u00f3bert","family":"Bidulsk\u00fd","sequence":"additional","affiliation":[{"name":"Asian Innovation Hub, Budulov 174, 045 01 Moldava nad Bodvou, Slovakia"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-9258-6939","authenticated-orcid":false,"given":"Marco","family":"Actis Grande","sequence":"additional","affiliation":[{"name":"Department of Applied Science and Technology (DISAT), Polytechnic of Turin, Viale T.
