Arc Welding Service

CATEGORY

TYPE

Seamless metal-powder cored wire without slag for M21

APPLICATIONS

Steel construction, shipbuilding, pressure vessels, mechanical engineering, pipe work, offshore, crane building, heavy transport, lifting equipment respecting the NACE requirements.

PROPERTIES

Seamless metal cored wire with remarkable stable arc and no spatters. Excelent for use in automated welding applications such as orbital Mag or robotic welding.This wire offers a unique covering range that anables you to use only one wire to cover more procedures upto 620N/mm2 yield strenght steels. AA M610 can also be used for constructions that needs post weld heat treatment after welding and still offers excellent impact properties. Due to the seamless production process the hydrogen content is below 3ml/100gr weld metal even after long storage.
