ArcBeadLayer helps welders and engineers choose heat settings that control distortion, hardness, and weld quality in a clear way. The app calculates heat input, arc energy, and cooling time so users can see how changes in speed, current, or voltage affect the weld. A multi-pass heat view shows how warmth builds up through layers, helping plan gaps for cooling when needed. Carbon equivalent and weldability checks guide choices on preheat, interpass control, and special steps for harder steels. Dynamic preheat and interpass suggestions use material, thickness, and weldability to reduce cracking and high hardness. Users can test parameter ranges against approved windows to stay inside qualified welding procedures. Tools for filler strength matching, pass sequence planning, and bead overlap support strong joints with consistent, even layers. ArcBeadLayer turns many hard welding calculations into quick checks that support safer, repeatable work in the shop or on site.
