The effects of welding current and arc voltage on
arc length was investigated. Mild steel plates of 10mm thickness and 50mm x
100mm diameter were joined together through Tungsten Inert Gas (TIG) welding
process for four (4) different intervals and the welding arc lengths were
measured consecutively. The measured arc length for each welding interval
increased from 1.19mm, 1.93mm, 2.54mm and 3.12mm as the current increased from
50A, 100A, 150A to 190A while the voltage also maintained the same increasing
trend from 200V, 240V, 280V to 320V. The minimum arc length values measured for
each welding interval with the aforementioned current and voltage range also
maintained an increasing trend, and that led to the conclusion that the higher
the welding current and arc voltage, the longer and wider the arc length which
is an influential factor to other welding attributes.
