Title: Small diameter arc stud welding method
Inventor: ANDOU HIDEO
IPC: B23K9/20
Filed: 1979-04-17
Abstract: PURPOSE: To stabilize the result of welding, and reduce the weight of the equipment, by starting an arc with a stud of specified small diameter being pressed against the material being welded, and performing stud welding by unlocking the welding gun after sufficient fusion of stud and base metal.  
     CONSTITUTION: A stud 20 of pointed end 20' measuring 2W12ϕ in diameter is mounted in a welding gun 19 through a chuck 21, and the end 20' is pressed against the base metal 22, and an arc is started by passing a current through a DC welding machine 18 to melt the end 20'. The stud 20 is locked by a solenoid 23 built in the welding gun 19 to be held in specified position, while the arc continues. After the end 20' of the stud 20 and the base metal 22 are sufficiently melted, the welding gun 19 is unlocked to push the sutd 20 into the molten pool to perform welding. In this method, since the current and welding time, which are main factors for the result of welding, may be arbitrarily adjusted and determined, the result of welding may be stable. Besides, since to capacitor is used in the main circuit, the equipment becomes light in weight and low in price.

Abstract: PURPOSE:To effectively expell the inclusions in molten steel by mounting a slidable outer barrel to the immersion nozzle of the continuous casting machine and intermittently moving the outer barrel upward and downward thereby changing the directio of the molten steel flow from the spouting port. CONSTITUTION:When molten steel spouting ports 11a, 11b are provided zigzag to the outer barrel 11 of an immersion nozzle 4 and an outer barrel is moved upward and downward intermittently, the amount and direction of the molten steel flow being spouted changes periodically. When the outer barrel is lowered, the amount of spouting from the spouting port 11a becomes maximum and the amount of spouting from the spouting port 11b becomes minimum so that the plane-direction molten steel flow in the mold 3 becomes the direction of F1. When the outer barrel is raised, the opposite state is shown and therefore by periodically repeating such changes, the slags and air bubbles included in the molten steel may be effectively floated.
