UNITOR RANGE OF MAINTENANCE ELECTRODES

The Unitor Arc Welding Electrodes range for Shipboard Welding includes electrodes for * Mild and low alloy steels * Cast steels * Heat resistant steel * Low temperature steel * Weathering steel * Stainless and acid-resistant steels * Tool- and machine-part steels * Cast iron * Aluminium and aluminium alloys * Copper and copper alloys * Air-carbon-arc gouging * Gouging with standard equipment

Product information

A product range selected for maritime use with the best welding properties

The Unitor welding electrodes range has been carefully selected to cover all normally occurring applications onboard. These high quality, high efficiency welding electrodes are designed for easy to weld even in difficult positions.

The versatility of Unitor welding electrodes enables each electrode to cover a wide range of applications that help vessel to reduce the number of electrode types needed on board and for welding standardization.

Features

Class (DNV-GL, ABS, BV and LR) approved for Joining electrodes
Low Moisture Absorption (LMA) properties for electrodes used in structural welding
High quality and high deposition efficiency
Recyclable high density polyethylene packaging for maritime conditions

Benefits

"LMA Electrodes" reduces the electrodes moisture absorption rate especially for high humidity maritime environment to avoid hydrogen porosities or cold cracking in weld
Easy to weld without high demands on the welder's skill ensuring high productivity
The packaging protects electrodes from moisture pickup, contamination and physical damage
The information label on packaging provides all relevant information including usage and application
