Abstract: A welding system for automatically welding a welding seam includes a welding arm, a sensor and a controller. The controller includes a welding seam contour detection component, a welding seam contour calculation component, a welding trajectory point calculation component, and a welding parameter setting component. The welding seam contour detection component is used for detecting an initial welding seam contour and detecting remaining welding seam contours after welding each layer of the welding seam. The welding seam contour calculation component is used for calculating the detected welding seam contours. The welding trajectory point calculation component is used for calculating welding trajectory points based on the calculated welding seam contours. The welding parameter setting component is used for setting welding parameters based on the calculated welding seam contours and the calculated welding trajectory points.

Abstract: In a method for comparing visual programs, a first object model is compared with a second object model, and a first difference object model and in particular a second difference object model are displayed. Differences in the programs are indicated in the difference object models by markings.

Abstract: In one embodiment, the invention provides a method of hardfacing a portion of a bucket subject to mechanical stress, the method comprising: contacting a surface of a bucket with a hardfacing filler metal connected to a welding nozzle to establish an arc between the surface and the filler metal and form a molten weld pool comprising the filler metal and a material of the surface; extending the filler metal into the molten weld pool to short circuit the arc; withdrawing the filler metal from the molten weld pool to re-establish the arc; moving the welding nozzle along the surface; and re-extending the filler metal into the molten weld pool to short circuit the arc, deposit additional filler metal into the molten weld pool, and liquify additional material of the surface into the molten weld pool.

Abstract: A welding method that utilizes a friction stir welding (FSW) technique to weld large structures, for example, very large cylindrical tower sections of wind turbines. The method involves welding at least two workpieces together by metallurgically joining faying surfaces of the workpieces. The workpieces are placed together so that their faying surfaces face each other and a joint region is defined by and between the faying surfaces. The workpieces are then friction stir welded together by forcing a tool into the joint region, rotating the tool about an axis thereof to cause the tool to penetrate the joint region, and causing the tool to travel along the joint region to form a weld joint that metallurgically joins the faying surfaces and produces a welded assembly comprising the workpieces.

Abstract: An approach is described for modifying subobjects of geometry objects based on per-subobject objects. A per-subobject object is associated with a sequence of components, such as a modifier stack, that are used to modify a geometry object. The per-subobject object may take one or more actions with respect to subobjects of the mesh object, such as applying data to specified faces. After a subsequent modification of the geometry object, the per-subobject object reapplies data to the faces that result from the modification. For example, the per-subobject object may specify the data to apply to faces that result from splitting faces during the modification or to faces that result from merging faces during the modification. The data for the faces may be accessed using a data channel that is associated with the per-subobject object.
