Welding Travel Speed
Compute the welding travel speed (arc advance) by dividing the bead length by the time taken, in mm/min. It is a fundamental parameter that, together with voltage and current, defines the heat input: welding too fast produces narrow beads with little penetration; too slow overheats and deposits excess material. Enter the bead length and the welding time.

Velocidade de soldagem
A velocidade de soldagem (ou velocidade de avanço) é a rapidez com que o arco percorre a junta, em mm/min — simplesmente o comprimento do cordão dividido pelo tempo. Apesar de simples, é um dos três parâmetros (com tensão e corrente) que definem o aporte térmico, e seu ajuste é uma arte. Soldar rápido demais deposita pouco material por unidade de comprimento, gerando cordões estreitos, convexos, com pouca penetração e risco de mordeduras; o resfriamento veloz ainda endurece a junta. Soldar devagar demais superaquece a peça (distorção, grão grosseiro), deposita material em excesso formando cordões largos e pode causar perfuração em chapas finas. A velocidade ótima equilibra penetração, geometria do cordão e produtividade. Em processos automatizados, é controlada com precisão pelo tartaruga ou pelo robô. Informe o comprimento do cordão e o tempo de soldagem.

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.
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.
TBM Advance Rate
Calculate a tunnel boring machine's daily advance, advance = PR·U·h, from the instantaneous penetration rate PR (m/h, advance while actively boring), utilization U (0-1, the fraction of time actually boring) and operating hours per day h. The distinction between penetration and utilization is central: penetration depends on geology and cutterhead thrust/torque, but utilization — typically only 30-50% — is limited by ring building, cutter changes, maintenance, muck removal and downtime. Real advance is far below nominal penetration, and improving utilization often pays more than increasing penetration. Enter the penetration rate, utilization and hours per day.
