down and dirty metallurgy

simple metallurgy podcast

The Video I wish I had in welding school

 

Please take advantage of our FREE Guide Books with links to Videos.

2 things every welder should know:

  1. Heat Affects metal
  2. Heat affects different metals differently

Heat affects carbon and low alloy steels differently than stainless or aluminum.

In this video podcast, I am trying to help students and beginners have a good grasp on how heat affects different metals.

I am almost 60 years old. I have been welding, fabricating, machining and engineering for a very long time and have never stoped learning. So much to learn in a lifetime. Your videos are great and have learned plenty from them. Keep up the great work. 🫡🇺🇸🙏

Frank Huston,

Glad you are responding well to the medical treatments and procedures. Praying for a speedy and complete recovery and can return to living your life completely. I have been a viewer and follower of your work for many years and have learned so much, Thank you.

Gerald Bickel,

I’m in my mid 70’s and wanted to finally learn some basics for repairs and hobby welding. Took a couple of “continuing education” classes locally. I really enjoyed it. One instructor recommended checking out your videos. You are a most excellent instructor and definitely have an encyclopedic level of knowledge of your craft. It’s fascinating. Thank you so much for doing this.

Len Kopec,

Hi Jody great to hear that your treatment is going well and heading for a full recovery. I’m a motor mechanic in my mid 50s and have always enjoyed modifying things. You have been the biggest single factor that has improved my welds over the years and would like to thank you for all the effort and countless hours you have spent making real world useful instructional videos, great work . Kind regards John

John S,

All I can say is you never stop learning. I am 84 and while I am a qualified boilermaker/welder I left the trade after I finished my apprenticeship and went surveying roads, rail lines etc and mainly used my fabrication and welding skills building race cars, trailers etc in my spare time. I never learnt Tig welding and self-taught via your video’s. I am still working at Tafe as a technician in heavy metal fabrication, light metal fabrication and fitting and machining. The lecturers in both fabrication shops regard me as being more knowledgeable in Tig than they are. I have passed on some of your videos to lecturers as teaching aids and also to interested students. My thoughts and prayers are with you for a full recovery.

Bob Goddard,

I learned how to weld by watching your video, I still have them.
Glad to see your still with us. Take Care.

William Gushulak,

You look like you are feeling quite well and that is great to see. Hang in there and do whatever you need to do to beat this thing. I am going to keep this podcast as my reference on future weld projects. Wished I had seen this years ago. Would have been a great help for me.
Thanks for doing these podcast for us “shade tree welders” like me.
Take Care & GOD bless you.

Keith Munn,

Magic, Jody. I look forwards to more in the series. Maybe one day, all being well, you’ll be able to make a workbook on metallurgy. Making a weld that looks aesthetically perfect is a goal we all have, but if it’s a weld that is going to fail down the line it is worse than useless. So, knowing this stuff is at least as important as knowing how to make a decent-looking weld. And, once you overcome the initial apprehension over anything to do with theory, it’s actually very interesting, and the more you learn the more interesting the metallurgy becomes.

Great video. I remember seeing the clips first time round, but it’s great to see it expanded and with the anecdotes, such as the acetylene soot.
