1. Determining the Influence of the Type of Shielding Gas during Additive Manufacturing of an Aluminum Alloy by Monitoring the Process Qualitatively and Analyzing Process Byproducts Quantitatively
Master-uppsats, KTH/MaterialvetenskapSammanfattning : This thesis analyzes the influence of process gases on the formation and the characteristics of process byproducts that emerge during additive manufacturing of an aluminum alloy belonging to the 2000 series. In order to address the influence, four pure gases, argon, nitrogen, helium, and carbon dioxide, were used as a shielding gas on the same parameter sets. LÄS MER
2. Researching and Developing Universal Gas Purging Solutions
Master-uppsats, KTH/Maskinkonstruktion (Avd.)Sammanfattning : In the welding of more sensitive metals such as stainless steel, titanium and some specific nickel alloys, the presence and application of a protective gas is essential. Without the use of a nonreactive shielding gas, defects occur in or adjacent to the weld joint, which vary from light discoloration of the weld bead to the direct onset and propagation of cracks.

3. Studie om ekonomisk lönsamhet och miljömässig påverkan av olika lösningar för skyddsgas
Uppsats för yrkesexamina på grundnivå, Karlstads universitet/Institutionen för ingenjörs- och kemivetenskaperSammanfattning : Most people agree that the Earth's climate is changing and that it's anthropogenic actions that are the cause of it. The year 2015 was a historic milestone for the Earth's future climate. A climate agreement was signed by several heads of government worldwide. LÄS MER
4. Undersökning av svetsegenskaper för svetsning med rörtråd kontra homogen tråd
Master-uppsats, Avdelningen för maskin- och materialteknikSammanfattning : Welding is a common method for joining of metal or plastic construction parts. This report describes several different weld methods in general terms. The report focuses on the GMAW method, specifically MAG welding. A case study has also been performed for the company Wenmec.

5. Plasmaskärning: Metod, användning & utvecklingsmöjligheter
Kandidat-uppsats, KTH/Industriell produktionSammanfattning : Plasmaskärning är en form utav skärande bearbetning i metall med hjälp av en plasmastråle som smälter ett skärsnitt i arbetsstycket. Plasmastrålen bildas genom att en elektrisk båge mellan elektroden i verktyget och arbetsstycket värmer upp en skärgas till ett plasmatillstånd. LÄS MER
