Fronius and the Business Unit Perfect Welding have been developing welding technologies and system solutions for arc welding and resistance spot welding since 1950 and have pushed forward the rate of progress in the welding technology sector in leaps and bounds. Today we are the global technology leader in the arc welding technology segment. With our innovative developments we have made applications possible that others had written off as unachievable, such as the thermal joining of steel and aluminium. The range of products offered by the Business Unit Perfect Welding includes manual and automatic power sources and complete systems as well as the related services.
