The later corresponded to the transition from orthorhombic phase to hexagonal phase and the melting behavior of hexagonal phase separately.
后者则分别对应于正交晶相向六方晶相的转变和六方晶相的熔融。

This article introduces all kind of control method of pulse melting pole in gas protection welding, and divided them into two kind: parameter control and melt dripping transition accurate control.
Causes include heating too quickly in the feed zone, melting too slowly in the transition zone, insufficient mixing, and excessive heat loss in the adapters or die.
