JIT Mech is one of a few companys in Sweden that is working with aluminum welding on thick materials. The background to this bachelor thesis is the problems caused when welding thick aluminum compared to welding on thin aluminum. The work positions is tearing on the workers and because of that JIT Mech is interested in mechanizing the production.   The purpose of the bachelor thesis is to look at different weldingproducts that on different levels would mechanize the welding production. The purpose of the preliminary study is to gain a basis for furthering the efficiency of the aluminum welding process to increase profitability, as well as improving the working environment for staff working in hot and uncomfortable situations. To solve the task, an observation study of production, as well as the interview of welders and supplier of the products have been made. A theory is written to review how aluminum welding works and explain what is problematic with it.   The comparison of the products is made with the greatest importance to how much the work environment can be improved depending on the level of mechanical welding equipment. A brief description of the products has been made, then a more detailed description of how much the products would change and improve welding production and remove static and weary workpositions for the welders compared with the current situation. Advantages and disadvantages have been developed for the welding products that gives a picture of how much they would improve the production. The conclusion was made that Fronius Flextrack 45 Welding Carriage is the best option for JIT Mech to invest in, as it improves the working environment while being the most affordable.   At the beginning of the work, it was planned to evaluate more products what was then impolemented, but after the project it was limited to only three products to simply keep the work within the timeframe. An important part of the welding process is to keep the weld hot throughout the welding to avoid tension and cracks in the material. It is not included in the evaluation as it is difficult to change that process. It became clear that there is no product at the moment that would completely automate the aluminum welding, but mechanizing the welding is still a big improvement. To get acquainted with this work taught me a lot about the thought process of development and investment to improve production, and hopefully my opinions can be a tool for future investment for JIT Mech.
