AA M400

Categorie 
type 
Seamless metal cored wire without slag for M21
applications 
Steel construction, shipbuilding, pressure vessels, mechanical engineering, pipe work, offshore, bridge building, heavy transport etc.
Properties 

Seamless metal cored wire with remarkable stable arc and no spatters. Excellent for use in automated welding applications such as orbital MAG or robotic welding. CEWELD AA M400 offers a more dense and higher filling rate to obtain better performance and productivity. CEWELD AA M400 can be used in a wide range of parameters starting from short arc at 14 volts for root weld or thin plate welding up to 32 Volts for extreme deposition rates. Due to the seamless production process the hydrogen content is below 3ml/100gr weld metal even after long unconditioned storage.
