Welding new Metro walk? (9)
I believe the answer is:
metalwork
'welding new metro walk?' is the definition.
I can't judge whether this defines the answer.
'new metro walk?' is the wordplay.
'new' is an anagram indicator.
'metro'+'walk'='metrowalk'
'metrowalk' is an anagram of 'METALWORK'.
Can you help me to learn more?
(Other definitions for metalwork that I've seen before include "Objects of gold, iron, copper etc" , "school subject, once" , "Creative manipulation of iron, tin etc" , "processing of gold maybe" .)
