‘A Welder’s Mate’ tackles every aspect of wet welding, and it does so in surprisingly laymen terms. I’ve used his book multiple times for my own research. Keats [author] fundamentally changed the way many underwater welding courses train their students with his training programs and this book.

Over the past year, Keats has been working tirelessly to bring his book to life in a new format – electronic.

Initially, he just planned to convert over the printed copy to e-format.

However, throughout the process, Keats found many opportunities to update his book’s index, terms and images to present-day versions.

The end result is nothing short of stunning.

It’s essentially a revised version of the original, though both the printed and ebook versions provide the same standard of techniques and skillsets used by underwater welders.
