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.

Consumo de gás de proteção
Nos processos MIG/MAG e TIG, um fluxo de gás envolve o arco e a poça de fusão para protegê-los do ar atmosférico — o oxigênio e o nitrogênio do ar contaminariam o metal líquido, causando porosidade, fragilização e perda de propriedades. O consumo é simplesmente a vazão (L/min) × o tempo de soldagem. A escolha da vazão é um equilíbrio: pouca deixa o ar penetrar (poros); muita não só desperdiça gás (que é caro, sobretudo o argônio) como gera turbulência, sugando ar para dentro da proteção — efeito contrário ao desejado. Saber o consumo permite dimensionar quantos cilindros levar para uma obra e orçar o gás, que é um custo significativo na soldagem a arco. O tipo de gás (argônio puro, CO₂, misturas Ar+CO₂) depende do processo e do material. Informe a vazão de gás e o tempo de soldagem.

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.
Gas-Oil Ratio (GOR)
Compute the gas-oil ratio (GOR) by dividing the produced gas volume by the oil volume, in scf/STB (standard cubic feet per barrel). It is a central petroleum-production parameter: it indicates how much gas accompanies the oil, characterizes the reservoir fluid type (black oil, volatile, gas-condensate) and sizes the surface separation equipment. A rising GOR can signal gas-cap breakthrough at the well. Enter the gas and oil volumes.
