摘要： A method of friction-stir welding, FSW, a joint J, for example a T joint J, between a first workpiece W1 and a second workpiece W2 is described. The method comprises: arranging the first workpiece W1 and the second workpiece W2; performing a first pass P1 of FSW of the joint J by moving therealong a first tool 10, comprising a first probe 100 rotating in a first rotational direction RD1 and at least partially inserted into the first workpiece W1 and/or into the second workpiece W2 to a first depth D1, in a first movement direction MD1 defining a first line L1, on a first side S1 of the joint J, thereby providing a first welded region WR1; and performing a second pass P2 of FSW of the joint J by moving therealong a second tool 20, comprising a second probe 200 rotating in a second rotational direction RD2 and at least partially inserted into the first workpiece W1 and/or into the second workpiece W2 to a second depth D2, in a second movement direction MD2 defining a second line L2, on a second side S2 of the joint J, thereby providing a second welded region WR2; wherein the first tool 10 and the second tool 20 are mutually opposed; and wherein performing the first pass P1 of FSW and performing the second pass P2 of FSW are at least partially concurrent.

摘要： A method of additive manufacturing an article from a feed material in a chamber includes evacuating at least some of a first gas from the chamber, thereby reducing a pressure therein from a first pressure to a second pressure and reducing the first gas from a first concentration to a second concentration. At least some of the first gas is then gettered from the chamber using a getter, thereby lowering the first gas concentration to a third concentration. The article is then additive manufactured from the feed material in the chamber using the getter as a substrate. The gettering comprises heating the getter at least in part using a fusion source, and the additive manufacturing comprises heating the feed material at least in part using the fusion source.
