Abstract (Swedish)
The importance of sustainable and effective energy usage is rapidly growing. SWEP International AB leads the manufacturing of brazed plate heat exchangers that offer effective heating and cooling applications used in various systems and industries. Stud bolts are manually welded onto the heat exchanger surface in their manufacturing process. A project to fully automate this process using an industrial robot has already begun at SWEP to increase the process productivity, quality, and
repeatability. The idea is to use a robot with an attached touch probe to measure points on the surface and sides of a heat exchanger in high precision to calculate a center reference point and account for any slight rotational offset. Then, the same robot... (More)

replace the manual bolt welding station with an automated robot cell solution. (Less)
