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.

Taxa de deposição (soldagem)
A taxa de deposição mede a produtividade bruta de um processo de soldagem: quantos quilos de metal são depositados por hora de arco aberto. As diferenças entre processos são enormes — o eletrodo revestido manual deposita ~1–3 kg/h; o MIG/MAG, 3–8; o arco submerso, 10–20 ou mais, soldando trilhos e cascos de navio. Mas atenção: a taxa de deposição é a velocidade com o arco aberto. A produção real depende também do fator de operação — a fração do turno em que o soldador está de fato soldando (e não posicionando peças, trocando eletrodos ou limpando escória), tipicamente só 20–40% no eletrodo revestido. Taxa de deposição × fator de operação × horas = produção real. Informe a massa depositada e o tempo de arco.

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.
Welding Preheat Temperature
Estimate the preheat temperature for welding, Tp = 350·√(CE − 0.25), as a function of the steel's carbon equivalent (CE). Preheating reduces the cooling rate, giving hydrogen time to escape and preventing the formation of brittle martensite and cold cracks in the heat-affected zone. Steels with a high CE require more preheating. Enter the steel's carbon equivalent.
Welding Heat Input
Compute the heat input of a weld, H = (V·I·60)/(v·1000), in kJ/mm, from the arc voltage (V), the current (I) and the travel speed (v, in mm/min). It is one of the most important welding parameters: it controls the cooling rate, the microstructure, the heat-affected-zone hardness and the cracking risk. High input softens and distorts; low input hardens and embrittles. Enter the voltage, the current and the travel speed.
