The disclosure relates to method and system for identifying a weldment feature. The method may include extracting a plurality of wire bodies from a sheet-metal model, and identifying from the plurality of wire bodies, a set of wire bodies associated with a face of the sheet-metal model. The method may further include generating one or more potential weldment features from the set of wire-bodies. Each of the one or more potential weldment features may be analyzed with respect to the face of the sheet-metal model. The method may further include identifying from the one or more potential weldment features, at least one related pair of weldment features. Weldment features of each related pair may include one of a contacting relationship and crossing relationship with each other.

A method for designing an additively-manufactured object includes: a slicing step of slicing a shape of the additively-manufactured object into weld bead layers each having a height corresponding to one bead layer using data of the shape of the additively-manufactured object, thereby generating a plurality of virtual bead layers; a reference direction setting step of setting, as a reference direction, a direction in which the sliced layer of the additively-manufactured object is continuously provided and extended in an intermediate layer disposed at a deposition-direction center of the plurality of virtual bead layers; and a bead adjusting step of adjusting a bead size of the weld bead to be formed in the plurality of virtual bead layers depending on a bead shape in a section perpendicular to the reference direction.

-- A method for welding together two parts along a weld line using a welding system enabling an operator to remotely perform welding operations. The operator defines reference points on the parts to be welded and/or on the weld line to be followed. A general movement direction of the welding torch is defined from the reference points. A local frame of reference is defined relative to the general movement direction of the welding torch. The welding torch is automatically moved from a welding starting point in the general movement direction. A flow of movement instructions linked to actions of the operator on the human-machine interface is generated to move the welding torch away from the general movement direction to adapt a trajectory of the welding torch to an actual shape of the weld line. The welding torch is moved corresponding to the flow of instructions generated by the human-machine interface.

Systems and methods for real time feedback and for updating welding instructions for a welding robot in real time is described herein. The data of a workspace that includes a part to be welded can be received via at least one sensor. This data can be transformed into a point cloud data representing a three-dimensional surface of the part. A desired state indicative of a desired position of at least a portion of the welding robot with respect to the part can be identified. An estimated state indicative of an estimated position of at least the portion of the welding robot with respect to the part can be compared to the desired state. The welding instructions can be updated based on the comparison.

A system for welding two pipes includes a first pipe clamp, a second pipe clamp, a weld torch, an inspection detector, a motor, one or more processors, and a grinder. The weld torch is configured to create a weld joint between the pipes at an interface region between the pipes. The inspection detector is configured to emit an inspection beam of radiation. The motor is operatively associated with the inspection detector to direct the inspection beam of radiation along the weld joint between the pipes. The one or more processors are operatively associated with the inspection detector to determine a profile of the weld joint between the pipes. The grinder is configured to grind at least a portion of the weld joint between the pipes based on the profile of the weld joint between the pipes.
