- MET-WELD makes welding equipments with advance technology. Submerged Arc Welding (SAW) machines are mostly used in heavy pipelines, tanks, vessels and cylinders manufacturing industries. SAW arc welding provides more operator comfort than any other arc welding process. The granular flux almost completely covers the arcs, which minimize blush, glare, heat, smoke and fumes. This process is typically some three to ten times faster than stick electrodes welding. The ripple free, no spatter submerges arc welds need machining or grinding. Slag peels off little or no chipping. Easy cleaning minimizes labour costs and speeds production. Submerged arc deposits are low in hydrogen, feature excellent crack resistance and generally superior weld quality and consistency.
Equipment Consists Of
- Thyristorised Power Source, Carriage mounted/Boom mounted Welding Head, Control Panel and Inter connection.
- Constant voltage / Current Power Source, Thyristorised Controlled, Fitted with Amps & Volt meter on control panel, Remote control facility provided, due to built-in voltage stabilizing facility no effect of input supply fluctuation on wire feed motor speed & output voltage.
Welding Head(Wire feeder)
- Four alloy steel rolls driven hardened case, Quick changeover of spool, Thyristorised D.C Drive permanent magnet motor to maintain constant speed of trolley as well as wire feeder.All control of power Source voltage setting, wire feeder motor speed, Carriage Motor speed and Reverse/Forward operations provides on control panel for easy access.
