A method and apparatus for supplying an inert gas under extreme pressure to a weldable air bag canister having a gas-charging opening in one end wall, and weld sealing the opening. The canister, and a composite welding head and weld ball supplying assembly, having a lower nose with a seal surrounding a ball dispensing opening therein, are relatively moved axially to seal off the opening in the canister end wall. Then, prior to pressurizing the assembly, an individual ball is presupplied through a passageway seal system to a ball delivery member inboard of the seals which axe provided in the welding head and weld ball supplying assembly. Thereafter, the composite assembly is charged with gas under a heavy pressure measured in thousands of pounds per square inch, and a raiseable and lowerable welding electrode, carried by the assembly axially in alignment with the ball receiving chamber and ball dispensing opening, delivers welding current to melt collapse the ball to seal the opening. Finally, the electrode is moved back to retreated position and the assembly is depressurized.
