Properties

CEWELD® AA MCrMo1V is a metal cored wire wire with Excellent weld puddle manipulation. Low spatter loss, without slag. Extremely crack resistant. Suitable for economic welding of CrMoV-steels up to 550 °C. Due to the seamless production process the hydrogen content is below 3ml/100g weld metal even after long storage in unconditioned conditiond. Good gap bridging properties. In the current range (PF) of 85 - 175 A for vertical up seams suitable.
