WebMar 20, 2024 · Metal cored wire with a spray transfer mode offers a very good profile, deeper penetration, and spatter-free welds. With Spray transfer, you can maximize the benefits of metal-cored wire by: 1) You can weld faster due to the higher melt-off rate, and. 2) Spray transfer produces little to no spatter, so it will minimize post-weld cleanup. WebMar 1, 2008 · Fifth, RMD creates a root pass weld with a 1/8- to 1/4-in. throat. In many instances, the amount of root pass metal deposited will be sufficient to support the heat input requirements of the first pulsed GMAW or FCAW fill pass. Fabricators can eliminate the GTAW hot pass, saving about $15 on a 12-in., schedule 40 pipe.
