Abrégé

A system (100), a method and an object template panel (150) are disclosed. The method comprises performing (A110) submerged arc welding to provide a respective layer (221-225) of an object (200) by means of a welding head (122), while moving the welding head (122) and the object template panel (150) relatively each other as constrained by a slot (152) of the object template panel (150), wherein the object template panel (150) is located to match, at least in height, a preceding layer (221-225) of the object (200), wherein the preceding layer (221-225) is preceding to the respective layer (221-225), whereby at least some flux is prevented from escaping through the slot (152), and vertically adjusting (A120) a distance (D) between the object template panel (150) and the support (130) based on a layer thickness of the respective layer (221-225) of the object (200), thereby locating the object template panel (150) to match, at least in height, the respective layer (221-225), whereby at least some flux is prevented from escaping through the slot (152).

Abrégé

A system (100), a method, an object support assembly (300) and a flux holding device (400) are disclosed. The system (100) comprises a welding head (122) for providing layers of material to additively manufacture the object (200) at a substrate (21), a flux holding device (400) for holding flux at the welding head (122), an object support assembly (300) having a support plate (320) provided with a plurality of ceramic panels (341-344) arranged adjacent to each other and arranged to form an outward surface (348) formed according to at least a portion of a shape of the object (200) to be manufactured. The method comprises providing (B110) a respective layer (221-225) of the object (200) using the welding head (122) by conveying (B120) the welding head (122) and the flux holding device (400) along the support plate (320) to apply the respective layer (221-225), and adjusting (B130) a distance (D) between a welding head (122) and the support (130) based on a layer thickness of the respective layer (221-225) of the object (200).

Abrégé

A method for additively manufacturing an object (200) using submerged arc welding is disclosed. The system (100) comprises a welding head (122) for providing layers of material to additively manufacture the object (200) at a substrate (21), and a frame assembly (500) for holding flux at the welding head (122), wherein the frame assembly (500), comprising at least one frame (501), is positioned on a support (130) and/or on a substrate (21) at which the object (200) is to be manufactured, wherein the substrate (21) is positioned on the support (130), wherein the system (100) is arranged to move the welding head (122) and the support (130) relatively each other in at least two dimensions. The method comprises operating (C130) the welding head (122) to form a respective layer (221-225) of the object (200) based on a shape of the object (200) to be manufactured, wherein the object (200) is formed by a plurality of layers (221-225) that comprises the respective layer (221-225), and wherein the method comprises, for at least some of the plurality of layers (221-225) of the object (200): providing (C140) at least one further frame (502) at said at least one frame (501), whereby the frame assembly (500) comprises said at least one further frame (502).
