(vii) Sometimes, blow holes and int

(vii) Sometimes, blow holes and internal porosities are removed by welding action at high tem-
peratures during hot working.
(viii) Non-metallic inclusions within the work piece are broken up. Metallic and non-metallic
segregations are also reduced or eliminated in hot working as diffusion is promoted at high temperatures
making the composition across the entire cross-section more uniform.
Typical Hot Working Temperatures
Steels 650–1050°C
Copper and alloys 600–950°C
Aluminium and alloys 350–485°C

(Vii) Kadang-kadang, lubang pukulan dan porositas internal yang dikeluarkan oleh pengelasan tindakan pada template tinggi
suhunya selama bekerja panas.
(viii) inklusi non-logam dalam benda kerja yang dipecah. Metallic dan non-logam
segregasi juga dikurangi atau dihilangkan dalam kerja panas seperti difusi dipromosikan pada suhu tinggi
membuat komposisi di seluruh penampang lebih seragam.
