Abstract
A gas lens assembly for an arc welding torch includes a lens body (24), a passage (30) through the lens body for receiving an electrode (48) therethrough and for permitting flow of an inert gas in the passage. A lens housing (32) is secured to the lens body. One or more openings in the forward end portion of the lens body enable the inert gas to flow from the passage into the housing. The gas lens assembly includes a flow control device (36) associated with the housing through which said inert gas is adapted to flow. The gas lens assembly includes a holder (34) for the flow control device releasably and removably attached to the lens housing whereby the flow control member may readily be replaced.
Claims
AMENDED CLAIMS
[received by the International Bureau on 21 October 1997 (21.10.97);
original claim 19 cancelled; original claims 16 and 20 amended; original claim 20 renumbered as claim 19; new claim 21 added;
remaining claims unchanged (2 pages)]
16. A gas lens assembly for an arc welding torαh comprising a lens body having a rearward end and a forward end, a passage through the lens body from its forward end to its rearward end for receiving an electrode therethrough and for permitting flow of an inert gas in a forward
direction in said passage, a lens housing secured to the lens body and defining a chamber around a forward end portion of the lens body, one or more openings in the forward end portion of the lens body enabling said inert gas to flow from said passage into said chamber, a flow control device in or adjacent said chamber through which said inert gas is adapted to flow in a forward direction, said flow control device comprising a plurality of parallel discs of porous metal having a combined
thickness and porosity for controlling the flow of inert gas therethrough so that the gas exits the plurality of discs as a laminar stream of gas moving in a forward direction, said laminar stream being adapted to blanket a weld puddle during a welding operation on a workpiece, and said plurality of discs comprising at least one disc formed from metal wire cloth and a perforated disc formed from nonwoven sheet metal, said discs being readily removable from the gas lens assembly for replacement.
17. A gas lens assembly as set forth in claim 16 wherein each disc of said plurality of discs is a thin porous metal disc.
18. A gas lens assembly as set forth in claim 17 wherein said plurality of discs comprises three discs, each disc having a different porosity.
15. A gas lens assembly as set forth in claim 18 wherein said three discs are in contact with one another.
20. A gas lens assembly as set forth in claim 17 wherein said plurality of discs have a combined porosity sufficient to create a pressure drop of between 003 and 113 psi across the disce at an air flow rate of between 20 and 40 cubic feet per hour.
21. A gas lens assembly as set forth in claim 16 wherein said perforated disc and said disc formed from metal wire cloth are substantially identical in size and shape and are in face-to-face contact with one another.
