{"openapi":"3.1.0","info":{"title":"Welding Settings API","version":"1.0.0","description":"Welding settings and consumables maths as an API, computed locally and deterministically — the amperage, wire and gas numbers a welder or fabricator dials a machine in with. (For joint strength, that is a separate weld-strength calculation.) The amperage endpoint gives a starting current from material thickness using the mild-steel rule of thumb of about one amp per 0.001 inch — so an eighth-inch plate runs around 125 A, give or take ten percent — and suggests an electrode or wire size to match. The deposition endpoint does the MIG arithmetic exactly: deposition rate (lb/hr) = wire feed speed × the wire’s weight per inch × 60 × efficiency, where weight per inch = (π/4 · d²) × 0.284 lb/in³ for steel, so 0.035-inch wire at 300 in/min lays down about 4.9 lb/hr fed, 4.8 deposited at 98 % — and from a target deposit it returns the arc time and the pounds of wire to buy. The gas endpoint sizes shielding gas: gas used (ft³) = flow in CFH × arc time in hours, and a cylinder’s arc-time duration, so 35 CFH empties an 80 ft³ bottle in about 2.3 hours of actual arc time. Everything is computed locally and deterministically, so it is instant and private. Ideal for welding, metal-fabrication, manufacturing and shop-management app developers, job-costing and consumable-planning tools, and welding-education software. Pure local computation — no key, no third-party service, instant. Machine settings, not joint strength. Live, nothing stored. 3 compute endpoints.","contact":{"name":"PremiumApi","url":"https://www.oanor.com/by/premiumapi"}},"servers":[{"url":"https://api.oanor.com/welding-api","description":"oanor gateway"}],"tags":[{"name":"Welding"},{"name":"Meta"}],"components":{"securitySchemes":{"oanorKey":{"type":"apiKey","in":"header","name":"x-oanor-key","description":"Get your key at https://www.oanor.com/developer/keys"}}},"security":[{"oanorKey":[]}],"paths":{"/v1/amperage":{"get":{"operationId":"get_v1_amperage","tags":["Welding"],"summary":"Amperage from thickness","description":"","parameters":[{"name":"thickness","in":"query","required":true,"description":"Material thickness","schema":{"type":"string"},"example":"0.125"},{"name":"unit","in":"query","required":false,"description":"in or mm (default in)","schema":{"type":"string"},"example":"in"}],"security":[{"oanorKey":[]}],"responses":{"200":{"description":"OK","content":{"application/json":{"example":{"data":{"note":"Mild-steel rule of thumb: about 1 amp per 0.001\" of thickness (so 1/8\" ≈ 125 A), ±10 %.
