I’m developing a set of custom aluminium parts and need a design engineer who can turn my concept sketches into fabrication-ready CAD data. The scope is purely Design and CAD modeling; I’ll handle machining and welding later once the files are final. You’ll translate rough ideas into precise, manufacturable geometry, keeping typical aluminium constraints in mind—bending radii, minimum wall thickness, and CNC-friendly tolerances. I usually work in SolidWorks, but STEP or IGES from Fusion 360, Inventor, or similar is fine as long as the models remain fully parametric. Deliverables • Detailed 3D models of each part • 2D manufacturing drawings with dimensions, tolerances, and material specifications • An assembly file confirming fit, cleara...
I need a robust arc-suppression circuit engineered specifically for my RF welding machine. The goal is simple and non-negotiable: stop destructive arcing before it reaches the generator or matching network, protecting the entire system from costly downtime and repairs. Key points you should know up front • Purpose: prevention of equipment damage only—operator safety circuits are handled elsewhere. • Architecture: solid-state components throughout; no relays or mechanical contacts. • Ratings: I will share the operating voltage and current range once we start, so your design must be adaptable within those limits. What I expect to receive 1. Schematic with clearly labeled protection stages (detection, quench, reset). 2. Bill of materials with manufac...
I have a large batch of product shots—iron gates, railings, and fencing—that need to look like they all belong on the same catalog page. Every image requires three touch-ups: solid color correction so the metal tones stay true, careful background removal, and cleanup of any dust, scratches, or welding marks that crept into the picture. Once the background is gone, I’d like you to decide which custom backdrop makes each piece pop. You’re free to test a natural outdoor setting, a subtle studio gradient, or even a soft blur; the goal is a cohesive series that feels premium and consistent across print and web. Here’s what I expect back: • High-resolution, print-ready files (CMYK JPEG or TIFF) • Web-optimized versions (sRGB PNG with transpare...

I have a conical rainhead to fabricate in stainless steel with a base diameter larger than 20 inches. Before any cutting begins on the workshop’s CNC plasma, I need a clean, ready-to-cut flat pattern that unfolds the cone accurately, includes all seam allowances, and clearly marks bend lines, notches, and any overlap for TIG welding. Send me: • A fully dimensioned 2D pattern in DWG or DXF • A PDF print for quick shop reference • A short note on the development method you used (SolidWorks sheet-metal feature, AutoCAD, Inventor, etc.) so my team can reproduce it later if we tweak the angles. Tolerance target is ±0.5 mm along critical edges; please keep that in mind when laying out arcs and stretch-outs. If you have produced flat patterns for large-di...

This project calls for a skilled welder who can recommend the best process—MIG, TIG, or Arc—once the specific joint design and material are confirmed. I’m still finalising whether the work will involve steel, aluminium, or stainless, and whether the end-goal is a repair, a fresh fabrication, or something decorative, so your guidance on technique, filler metals, and required prep will be valuable. You’ll need to supply your own equipment, demonstrate consistent bead quality, and meet standard safety practices. Clear photos or short clips showing set-up, test passes, and finished welds will serve as acceptance criteria. Please outline the process you would follow, the codes or standards you normally work to, and typical turnaround times.

The geometry is finished; this is purely a detailing exercise. If anything is unclear once you open the files, just fl...
I have a production-ready, IGBT full-bridge welding inverter that already powers both TIG and MMA processes, yet the embedded side still needs a final expert pass before release. The control board is built around 8051 and STC MCUs running Keil C51 firmware, and every line of code directly shapes arc stability, HF start, AC balance, soft-start, and safety interlocks. The short-term goal: review, tidy, and extend the existing code so it drives the power stage flawlessly in TIG and MMA, AC and DC. That means refining PWM timing, gate-drive dead-time, current-feedback filtering, and all the little state-machine details that separate a decent welder from a great one. Core tasks and deliverables • Audit the present C51 codebase, flagging race conditions or timing pitfalls. &b...
