Weld Dilution
Compute a weld's dilution, D = (melted base-metal area / total bead area)·100%, the proportion of the bead that came from the base metal rather than the filler. It is crucial in cladding and dissimilar-metal joints: high dilution mixes in more base metal, altering the bead's composition and properties (anti-corrosion cladding aims for low dilution). Enter the melted base-metal area and the total bead area.

Diluição na soldagem
Quando se solda, o arco funde não só o metal de adição (o consumível), mas também parte do metal base da peça — e os dois se misturam na poça. A diluição D = (área de base fundido/área total do cordão)·100% mede essa mistura. Seu controle é crítico em duas situações. No revestimento (cladding) anticorrosão ou antidesgaste, quer-se baixa diluição (10–15%): o objetivo é depositar a liga nobre pura na superfície, sem 'contaminá-la' com o aço base por baixo. Já na união de metais dissimilares, a diluição define a composição final do cordão e se ele será frágil ou tenaz — soldar inox a aço carbono, por exemplo, exige calcular a diluição para escolher um consumível que resulte numa microestrutura sã (usando diagramas como o de Schaeffler). Informe a área de metal base fundido e a área total do cordão.

Weld Deposition Rate
Compute a weld's deposition rate by dividing the mass of deposited metal by the arc-on time, giving kg/h. It is a central indicator of process productivity: processes like submerged arc and MIG/MAG have far higher rates than stick electrode. Combined with the operating factor (actual arc time), it estimates a joint's output. Enter the deposited mass and the arc time.
Metallostatic Pressure
Calculate the metallostatic pressure exerted by molten metal at the bottom of a mold, P = ρ × g × h, from the molten metal density ρ (kg/m³), gravity g and the metal column height h (m). The result, in pascals, is the pressure the molten metal exerts on the mold walls and bottom due to its own weight — analogous to hydrostatic pressure, but with the high density of metals. It is essential to size the mold strength (which can 'burst' or deform under pressure), predict core flotation and metal penetration into gaps. Dense metals (iron, ~7000 kg/m³) generate high pressures. Enter the metal density and the column height.
Electrode Consumption
Estimate the number of electrodes needed for a weld by dividing the total mass of metal to deposit by the mass deposited per electrode (rounding up). It is a practical planning and budgeting calculation in stick-electrode welding, avoiding over-buying or stopping the job for lack of consumables. Enter the total weld mass and the mass deposited per electrode.
