A welding apparatus spot welds an upper sheet and a lower sheet together. A substantially semi-circular hole or notch is formed at an edge of the upper sheet at the desired location of spot welding. When the semi-circular hole or notch is formed, the process does not wrinkle or deform the upper sheet. A clamping cup of the welding apparatus surrounds the semi-circular hole or notch and contacts the upper surface of the upper sheet. A plasma arc torch heats the sheets, allowing entrapped vapors in a coating on the lower sheet to vent freely to the atmosphere. Filler wire is added and melted to fill the semi-circular hole or notch and to secure the overlapping sheets together.

A gas delivery and purging device for an additive manufacturing chamber includes at least one flexible gas tube having a gas inlet, a purging gas outlet, and a sidewall which defines a shape of the tube, and a source of purging gas operatively connected to the at least one flexible purging gas tube for selectively delivering the purging gas to the at least one flexible purging gas tube. The gas outlet includes pores defined in substantially an entire surface area of the sidewall such that the purging gas passes through the pores and is thereby released into the chamber and is suitable for delivering a large volume of purging gas in a laminar flow.
