PROCEDURE AND DEVICE FOR JOINING SOLARADURA SONGS OF SHEET.

摘要

THE SHEETS (3.1, 3.2) OF SHEET TO BE WELDED, IN ACCORDANCE WITH THE INVENTION, ARE PREVIOUSLY HEATED TO THEIR PRELIMINARY WELDING, GENERATING A GRADIENT OF TEMPERATURE WITH THE SAME SPEED OF WELDING IN THE PROCEDURE USED FOR WELDING, BEING THIS SMALLEST GRADIENT REGARDING THE MATERIAL TO BE SOLDED. THEREFORE, THE WELDING SPEED CAN BE RAISED OR THE MATERIAL CAN BE WELDED IN SUCH MODE, WHICH WITH HIGH TEMPERATURE GRADIENTS WILL HAVE A WELDED WELDING QUALITY. PRIOR WARMING IS PERFORMED BY EXAMPLE BY EXCITATION WITH HIGH FREQUENCY OF THE MATERIAL TO BE SOLDED.
