INERT GAS COVER SYSTEM FOR LASER WELDING WITH A BASE AND WALL HAVING AN OPENING

摘要

An apparatus for laser welding comprises a base (402), a wall (406), and an opening (414) in the wall. The base (402) has a first end (410), a second end (412), and a channel system (404). The channel system (404) is located closer to the first end (410) than the second end (412) of the base. The wall (406) extends from a side of the base (402) to partially enclose the channel system (404). The opening (414) in the wall (402) is located closer to the second end (412) than the first end (410). The shape of the wall (406) is capable of retaining a gas introduced through the channel system (404) in a welding location and causing the gas to move away from the channel system (404) and through the opening (414) in the wall (406).
