ESAB OK 55.00 VacPac E7018-1H4R AWS A5.1/ASME SFA 5.1 - 3/32" (2.4 mm) x 14" (355 mm) SMAW Electrodes (3.74lb Container)
Classification:
SFA/AWS A5.1 : E7018-1H4 R
OK 55.00 is an exceptional, all-position, low hydrogen basic electrode, particularly suitable for critical applications requiring exceptional impacts at low temperatures. This electrode provides a smooth, stable arc with very low spatter. Excellent arc starting is enhanced by a special graphite tip on the electrode.
The complete slag coverage provides easy removal and minimal post-weld cleanup. OK 55.00 is intended for a wide variety of carbon, low alloy, and hardenable steel. The weld metal is also very resistant to hot cracking. OK 55.00 meets the requirements of 4 mL diffusible hydrogen content in 100 g of deposited weld metal. In addition to standard packaging, OK 55.00 is available in VacPac™ packaging to ensure the lowest possible moisture content and eliminate the need for costly rebaking procedures.
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 makes them a simple choice for welders of all skill levels.
