A method for assisting a fitter in fitting parts to profiles for manufacturing construction elements of a steel construction, the parts consisting of plates, profiles or bolts, wherein the method comprises:
- providing a computer system in which a 3D-model of the steel construction is created by means of a CAD-program;
- providing a software application for generating fitting information, wherein the software application interprets 3D-model data of the 3D-model and generates for at least one mark or phase of the steel construction from the 3D-model data at least the following fitting information:
- a digital or physical list of parts which provides the logistical order in which the parts are supplied to the fitter;
- a digital or physical list of profiles which provides the logistical order in which profiles are supplied to the fitter;
- specific welding parameter information for each part which has to be welded to a respective profile;
- and
- graphical information which is presented on a screen which is in the working environment of the fitter,
- wherein the graphical information includes at least one of:
- various views of a profile in combination with a part to be connected with the profile;
- information on how to position a part relative to a profile;
- and
- information with respect to distances of the part relative to reference points, the reference points including at least one of an end face of the profile, holes in the profile or markings on the profile, so as to determine a precise position of the respective part on the respective profile relative to the reference points,
- wherein the fitting information is provided to the fitter and wherein the fitter performs the following method steps for the at least one mark or phase of the steel construction for which the profiles have to be fitted by the fitter:
- a) obtain the digital or physical list of profiles generated by the software application for the respective mark or phase and determine whether a next upcoming profile is available for processing, and
- a1) if available, taking a next upcoming profile from the list for processing by the fitter and proceed at step b);
- and
- a2) if not available, end the method;
- b) obtain the digital or physical list of parts generated by the software application for the respective mark or phase and present a next upcoming part from the list to the fitter;
- c) orient and position the part in the correct orientation and position relative to the reference points of the profile using the graphical information which is presented on the screen which is in the working environment of the fitter;
- d) tack-weld the respective part to the respective profile;
- and
- e) determine whether all parts for the respective profile have been connected to the profile and restart at step b) if the determination is “no” and restart at step a) if the determination is “yes”.
