Investigation over how different laser parameters affect the welding depth and formation of pores for laser welded copper hairpins (English)
Abstract [sv]

Detta examensarbete handlar om lasersvetsning av koppar-hairpins som används som statorlindning i elmotorer. Vid lasersvetsning kan olika parametrar väljas som lasereffekt, matningshastighet med mera. I arbetet har en litteraturstudie om hur svetsdjup och porbildning undersöks, ett svetsningsexperiment där laserparametrarna effekt och antal varv varierat samt en mikroskopsundersökning genomförts. Arbetet kom fram till att olika parametrar har olika påverkan på hairpinsens egenskaper och defekter, till exempel större svetsdjupet ger lägre resistans och porer som ofta uppstår påverkar hållfastheten. Utifrån experimentet och undersökningen visar arbetet att porer kan undersökas och svetsdjup kan mätas med mikroskop och mikroskopsbilder.

Abstract [en]

The thesis is about laser welding of copper hairpins used in electric motors as stator windings. There are different selectable laser parameters such as effect and feed rate when laser welding. A literature study on how welding depth and pore formation can be investigated, a welding experiment where the parameters effect and the welding path varied and a microscopic analysis was carried out. The thesis showed that different parameters affected the hairpin’s characteristics and defects, for example a greater welding depth gave a lower resistance and pores that often occur affect the strength of the weld. The experiment and the analysis proved that welding depth can be measured and pore formation can be investigated with a microscope and microscopic photographs.
