Excellent welding properties with easily controllable flow permits spatter free welding with very low current. Due to the very low heat input and unique composition of Ni(-) the transition zone will stay well machinable and is therefore well suited to use as first layer in case off multi-layer welding. The weld metal will show no undercut !
Preheating is normally done to slow down the cooling speed, in case you can not control the cooling speed it is better to keep the work peace at a low temperature during welding and hammer immediately after welding.
