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.

Consumo de eletrodos
Quantos eletrodos comprar para uma obra? O cálculo parte da massa total de metal a depositar (estimada pelo volume da junta × densidade do aço) dividida pela massa depositada por eletrodo. Esta última não é a massa total da vareta: descontam-se o toco não aproveitado (~5 cm que sobram na garra), o revestimento que vira escória e gás, e as perdas por respingo — o conjunto define a eficiência de deposição do eletrodo (tipicamente 60–70% para revestidos comuns). Subestimar o consumo para a obra na pior hora; superestimar empata capital em consumível que vence (eletrodos básicos absorvem umidade e precisam de ressecagem). Por isso a conta entra direto no orçamento e no planejamento de compras. Informe a massa total da solda e a massa depositada por eletrodo.

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.
Shielding Gas Consumption
Compute the shielding gas consumption of a MIG/MAG or TIG weld by multiplying the flow rate (L/min) by the welding time (min), in liters. The gas (argon, CO₂, mixtures) protects the molten pool from atmospheric contamination. Knowing the consumption lets you size cylinders and budget — and adjust the flow, since excess wastes gas and can cause turbulence and porosity. Enter the gas flow rate and the welding time.
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.
