Abstract
601,459. Electric welding. NELSON, T. April 27, 1945, No. 10677. [Class 83 (iv)] In welding studs to plates &c. a refractory ferrule is slidably fitted over the end of the stud and has vent slots in the end adjacent the plate to allow gases, set up during welding, to escape. The ferrule 4, Fig. 1, consists of a sleeve of refractory material such as porcelain having a bore 6 large enough to permit axial movement on the stud 2. An enlarged bore at one end forms a small chamber 7 around the stud and radial vent slots 18 are formed in this end. The stud is resiliently held by the jaws of a chuck 17 and a spring 12 is fitted over the jaws, its coils 13 engaging threads thereon at one end whilst close coils 9 lightly grip the neck 8 of the ferrule at the opposite end. In operation, the spring and ferrule are adjusted so that the ferrule is flush or “ inch proud of the end of the stud and the assembly is pressed against the work 3 ; as the stud is withdrawn to-create an arc, the spring ensures close contact of the ferrule and work. The hot gases escape through the vent slots, thus avoiding blow-out and spatter of hot metal, and producing even heat conditions. After completion of the weld, the remains of the ferrule may be left or removed by breaking with a hammer blow &c.
