Paul,
Is there any effect on the metallurgy of the liner due to the heating during
the welding process that could adversely affect the apex seal sealing and or
wear?

I can't detect any. The apex seals cannot seal in this area as they
are wide open on both sides as they pass over the intake port.
That is why the differential pressure from chamber to chamber is
zero in this area. Tig welding is a very localized heating process.
Obviously the steel must be heated to melting temperature but
a few hundreds of an inch away the aluminum is not melted.

This process flies in the face of intuition. The metal has a
worse time of it down by the peripheral exhaust ports where
the heat can be 1800 F for thousands of hours.
