Autodesk Inventor / CAD Specialist for Parametric Weld Geometries and Welding Sequences — 300 to 400 Technical Images

PROJECT TITLE Autodesk Inventor / CAD Specialist for Parametric Weld Geometries and Welding Sequences — 300 to 400 Technical Images PROJECT OVERVIEW We are creating a consistent library of technical welding illustrations for a digital welding application. An Excel combination matrix will be provided. It defines the product form, weld type, welding position, weld details and joint preparation for every required image. The current matrix contains 150 valid combinations. At least two separate images are required for each combination: 1. Weld joint geometry 2. Welding sequence with realistically arranged and numbered weld beads The basic scope is therefore 300 images. Additional step-by-step welding-sequence images may increase the final scope to approximately 300–400 images. REQUIRED SPECIALIST We are looking for an experienced CAD designer or mechanical design engineer with: - Advanced Autodesk Inventor skills - Experience with parametric 3D models - Experience creating technical drawings and cross-sections - Knowledge of welding joint preparations and multi-pass welding - Experience with iLogic, macros or automated variant generation - Ability to work systematically from an Excel combination matrix - Experience with technical rendering - Good written English - Willingness to provide all editable CAD source files A general graphic designer without CAD and welding knowledge is not suitable for this project. COMBINATION MATRIX Each row of the supplied Excel matrix must be treated as a separate production item. The matrix contains the following fields: - ID - Product form - Weld type - Welding position - Weld details - Joint preparation - Geometry filename - Geometry status - Welding-sequence filename - Welding-sequence status - Notes and validation Product forms: - PP = Plate to plate - TP = Tube to plate - TT = Tube to tube Weld types: - BW = Butt weld - FW = Fillet weld Weld details: - ss = Single-pass or single-sided version, as defined in the matrix - ml = Multi-pass or multi-layer version, as defined in the matrix The welding position must not appear only in the filename. The spatial orientation of the workpiece and weld must correspond to the specified welding position. WELDING POSITIONS Depending on the matrix, the library may include: - PA - PB - PC - PD - PE - PF - PG - H-L045 - J-L045 - PH - PJ The workpiece orientation, weld direction and bead arrangement must be technically consistent with the specified position. JOINT PREPARATIONS The library shall cover the following joint preparations where technically compatible with the selected product form and weld type: - Square butt joint / I-groove - Single-V groove - Double-V groove / X-groove - Single-Y groove - Double-Y groove - Single-bevel groove / HV groove - Single-bevel groove with root face / HY groove - Single-HU groove - Double-bevel groove / K-groove - Double-HY groove - Double-HU groove - Double-V bevel / DV or K joint - U-groove - Double-U groove - J-groove - Double-J groove - Flanged-edge weld - Fillet weld - Single-sided fillet weld - Double-sided fillet weld - Plug weld - Slot weld - Spot weld - Seam weld / roller seam weld Not every joint preparation may be combined automatically with every product form, weld type and welding position. The contractor must identify and report technically invalid or unclear combinations before producing the corresponding images. GEOMETRY IMAGE REQUIREMENTS Each geometry image must contain two technically identical representations: - Top: perspective 3D representation of the components - Bottom: technical cross-section of the same component geometry The upper 3D geometry must be generated from the same parametric cross-section shown below it. If the lower cross-section is extruded, it must produce exactly the geometry shown in the upper 3D view. The following are not acceptable: - Different bevels in the 3D view and cross-section - M
