COATED ELECTRODES

Unitor LMA electrodes

Electrodes with special coating properties. LMA stands for Low Moisture Absorption, i.e. low moisture pick-up. LMA gives you less problem with porosity.

An LMA- electrode is drier than ordinary electrodes from the very beginning. The pick-up of the surrounding air humidity during the day is very low. The electrode can be exposed longer and will still give you a porosity free weld metal. LMA will decrease the risk for HAZ cracking. (Cold cracks/Hydrogen cracks) If you weld high tensile steels or very thick plates of medium strength, you will gain extra security with LMA electrodes. The risk for hydrogen cracking in the heat-affected zone will decrease.

All other properties are unchanged. The LMA- coating does not affect other properties.

You will still get

• the same good weldability • the same mechanical properties • the same low fume formation
