In heavy plate fabrication, conventional welding requires wide beveling and dozens of passes. DAIHEN's D-Arc (Deep Penetration Arc) welding system transforms thick-plate fabrication productivity.
Employing a highly concentrated, stiff electric arc alongside specialized digital feeding controls, D-Arc delivers single-pass penetration up to 19mm. For plates up to 25mm, full-penetration butt welds can be completed without complex edge preparation.
Compared with conventional multi-pass GMAW, D-Arc reduces filler metal usage by up to 70% and boosts overall welding efficiency by over 80% across heavy machinery, bridges, and pressure vessel manufacturing.
