Process for evaluating weld joint comprises subjecting joint to ultrasonic testing using ultrasonic waves, registering time-dependent sound permeability changes in the waves and determining time at which melt forms in joint
Process for evaluating weld joint comprises subjecting joint to ultrasonic testing using ultrasonic waves, registering time-dependent sound permeability changes in the waves and determining time at which melt forms in joint
Process for evaluating a weld joint between two joining partners (1, 2) comprises: subjecting the joint to ultrasonic testing using longitudinal and transversal ultrasonic waves; registering time-dependent sound permeability changes in the longitudinal and transversal ultrasonic waves separately from one another; and determining a point in time at which a melt (11) forms in the area of the joint. Process for evaluating a weld joint formed during welding process between two joining partners (1, 2) comprises: subjecting the joint to ultrasonic testing using longitudinal and transversal ultrasonic waves, registering the time-dependent sound permeability changes in the longitudinal and transversal ultrasonic waves separately from one another, and determining a point in time at which a melt (11) forms in the area of the joint based on the ratio of the changes and using a basis for the evaluation of the weld joint.
