A NEW METHOD FOR THE NON-DESTRUCTIVE TESTING OF SPOT WELDS,

Abstract

The spot-welding technique, a process employed in almost all phases of metal processing, is being used for load-bearing and highly-stressed building components at an increasing rate. Since it became possible to join components up to 25 mm thick by means of spot-welding, this technique is also being employed in steel construction. In this application faultless spot-welds are mandatory. Similar conditions prevail also in the field of aircraft and vehicle manufacture, where the joints are subjected predominantly to dynamic stresses. The problem of economical quality control is an especially important one in the field of aircraft manufacture, where the requirements imposed on the quality of the welds in the components are high. A method for the testing of spot-welds which is based on the penetration of the item to be tested by ultrasonic radiation is described.
