So, how easy is it to weld HDPE? *I.e. if I get suitable welding rod
and a suitable heat gun will I be able to mend a couple of HDPE water

Any experience/comments most welcome.

If you are talking pipes, there are welding connectors that have an
electric element in them. The pipes are slotted in and a certain
current passed for a certain time and the jobs done.
