WeldKit: Welding Calculators Built for the Shop
Welding calculators built for quick shop use on iPhone and Android.
Shop-ready welding math, in your pocket
WeldKit is a welding calculator app built for welders, fabricators, and metalworkers who need fast, practical numbers before striking an arc. Use it on the shop floor for setup baselines, travel cards, and quick estimates—without flipping through binder charts.
The same TestTalkHQ philosophy behind our web calculators: readable outputs and tools you can use with gloves on.
