An experimental investigation into tube to tube-plate welding using the impactor method

A study has been carried out to explore the explosive welding of tubes to tube-plates, considering various metals and using a parallel set-up employing an impactor and high detonation-velocity explosive material. The parameters for the securing of an acceptable weld have been found experimentally and have been compared with equivalent theoretical values. The technique has been extended to the employment of simultaneous detonation at multiple locations and successful welds have been realised without appreciable distortion.
