ZRM Enterprises has a Lincoln Electric NA-5 submerged arc welding system.  It's a fully automated way to perform circumferential and vertical/horizontal butt and fillet welds, without using a shield gas.  Our main application is surface build-up, single-pass  welding steel.  Although we are capable of performing multi-pass butt and fillet welds, as well as, welding non-ferrous materials.  Contact us for a quote today or for more information!
