Analysis of welding processes

Quality assurance and ways of working



The Boliden Rönnskär Smelter produces metals, mainly copper. The Rönnskär Smelter is located in Skelleftehamn, Västerbotten Sweden. At the site a lot of welding repairs and rebuilds are performed. In some applications there are high demands of welding quality to be able to fulfill laws and regulations. Current situation regarding welding quality assurance is that some of the quality assurance conditions are met, others are not.


We would like to develop a better strategy for level of welding quality assurance based on which types of welding activities to do on our own and which activities we with advantage will let contractors perform.



The project would consist of:

• Understanding of welding quality assurance

• Gather information regarding current state regarding documentation, welder certification, material certification, storage of material, controls/testing, welding equipment, procedures WPQR, instructions WPS.

• Investigate which needs or demands Rönnskärs have of welding quality assurance.

• Analysis of gap and development of a proposal to reach the future state


Part of the thesis work needs to be performed at site to be able to gather information in a good way.


Thesis complexity ~15 credits.



An analysis of current state and proposal of future state regarding welding quality assurance process.

If possible also recommendations about activities needed to reach the future state.
