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. The task received from the company was to compare the mechanical properties of joints welded with the tube electrode called Nittetsu SM-3A and joints welded with the homogenous electrode called ESAB Aristorod 12.63. Both types of weld joint were welded with the MAG method with an Argon based shielding gas with 18% CO2.

Syftet med denna rapport är att visa hur en ökning av isolertjockleken i ett hus påverkar kostnader och energiåtgång för isoleringen i ett livscykelperspektiv, samt för husets bruksskede. I studien har en optimering av isoleringen på ett pågående byggprojekt i Växjö, kv Limnologen, utförts. Total energiåtgång för isoleringens livscykel har tagits fram från tidigare utförda livscykelanalyser (LCA). Husets värmebehov har beräknats mha information från ritningar och kontakter med personer i anknytning till kv Limnologen. En ekvation har utformats för att finna ett teoretiskt optimum för isolertjockleken med inriktning mot total energiåtgång, koldioxidutsläpp och ekonomi.

Swedish energy policy aims to increase the use of energy from renewable sources and this should be done in a safe, environmentally and sustainable manner. According to the Energy Agency the use bio-fuel increased by 73% between 1990 - 2006. Stands with high share of slash are often located on areas with high productivity which often are located on soils with poor bearing capacity. This will increase traffic on susceptible soil leading to increased ground damage. To reduce the risk of ground damage at slash-forwarding, ground protection is needed.

The long-term external financing of a corporation is satisfied through the bond market where issues of index-linked bonds, which are discussed in this thesis, is one alternative. (Finnerty&Emery 2001) An index- linked bond is a debt instrument where the investor is guaranteed the principal and premium amount in real terms. As the bonds cash flows are indexed to the inflation this implies that the issuer of an index-linked bond assumes an inflation risk. Purpose: The purpose of this thesis is to describe and examine corporate motives for choosing index-linked bonds as way of financing their business. Realization: Primary data was collected through interviews with corporate issuers of non-swapped index-linked bonds.

As demand for renewable energy is increasing rapidly, the market for biomass pellets is expected to continue to grow in the near future. Most of the new raw materials that are discussed for pellet production have one thing in common; the production costs will increase compared to using traditional raw materials such as sawdust and planer shavings. The aim of this thesis is to investigate to what degree increased use of new raw materials for pellet production will affect the general pellet prices in Sweden and to survey what plans Swedish pellet producers have concerning new raw materials. To investigate the raw material situation of the Swedish pellet producers an industry survey was performed. Literature studies were also made on previous research in the subject field. Calculations of the production costs for pellets were done for the raw materials sawdust, wet sawmill chips and energy wood respectively. New raw materials are already used by the large-scale pellet producers in Sweden.
