Method of Controlling Arc Welding on Ultrathin Board

Article of Honda R&D Technical Review Vol.15 No.1


A positive proportional relation between arc length and arc illumination was found to apply in arc welding. By applying this relation, a control technology was developed that maintains arc length at a constant fixed value during welding. This enabled control that is able to maintain a fixed arc length of 1.0 mm or less, which was not possible with conventional arc voltage control. As a result, stable, uniform melting was achieved on ultrathin boards 0.5 mm thick or less by the application of low-current, low-voltage welding.
