Abstract
Multimaterial lightweight design requires new materials new joining processes and new joining concepts Intensive research and development activities on the part of all market players in some cases also in joint projects is driving technology development forward For the welding technology specialists from Fronius the focus is on high process speeds easy parameterisation minimised thermal input and excellent gapbridging abilityLegislation that explicitly mandates lower CO2emissions from motorised private vehicles is necessitating more and more lightweight construction concepts According to a recent study by Drucker Worldwide in collaboration with the European Aluminium Association EAA between 1990 and 2012 the amount of aluminium going into the average car almost tripled from 50 to 140 kg This is forecast to increase to 160 kg or even as much as 180 kg per car by 2020 As well as the lightweight material aluminium everlarger quantities of highstrength
