ESAB MW1
ESAB MW1
ESAB MW1 is a copper coated, Mn-Si alloyed solid wire for GMAW of non alloyed steels, used in general construction, automotives, ship building and pressure vessel fabrication. The wire has a carefully controlled wire chemistry and a unique surface technology providing superior weld metal quality at high wire feed speeds and at high welding currents.
Welding Invented
When our founder Oscar Kjellberg developed the world's first coated welding electrode in 1904, he launched a company whose innovation and uncompromising standards have helped create the history of welding itself. This legacy continues in the quality, performance, and continuous development of the mild steel welding electrodes we make today.
Consistent Performance and Quality, Every Time
Performance is still what sets ESAB covered electrodes apart. No matter the job at hand, with ESAB mild steel and low hydrogen electrodes you are assured of good penetration, consistent mechanical properties, and X-ray quality welds from batch to batch.
Setting the Standard in Covered Electrodes
ESAB covered electrodes exceed industry criteria for low moisture pick up (moisture pick up 0 to 1000°C < 0.4 after 9 hours at 274°C, 80% HR). You can trust ESAB low hydrogen and mild steel electrodes to deliver tough mechanical properties in high or low temperature environments, high humidity worksites, or the most challenging positional welding projects. Plus, their easy-to-use nature make them a simple choice for welders of all skill levels.
