2.Welding Operation:


(1)Storage:


As per flux cored wire.

 

(2)Note:


Solid wires for low alloy steel normally take the weld method of MIG or MAG. The suggested gas flow should be 20~25 l/min. When welding in windy places, the possibility of porosity is high, so wind shielded facility is necessary. Turbulence will happen when the gas flow is too high, causing porosities in the beads. 

 

The welding suggestion is that in workable situation, lower the current, stick-out-length, and the width of weaving, to prevent the alloy from burned and cell enlargement.
