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.
