- Bob and Sparky introduce us to the world of welding. They cover SMAW or "Stick" welding, GTAW or "TIG" Welding, and GMAW or "MIG welding. Bob stresses the importance of filler metal and shielding gas.

Am a little below average IQ your clear and simple tutorials have helped me a lot......thank you.
You have some of the best welding videos I've seen. I would love it if you created more.
Video is excellent. I will be using it in my intro to welding classes.
this is the best explanation in a short time....long way to go bob/////keep making videos,,...thanks bob.
I have go through lots of videos regarding welding but this video made me understand clearly thanks Bob.
Awesome video, thanks a lot! I'm from Brazil and I learned a lot from your videos.
Excellent presentation!👍🏽🌵
I needed this, thank you.
Great Video Bob
that was so helpful,finally found some teaching videos,thanks!
Great videos - I will be using them to help introduce welding to my high school beginner students. A stick welding video similar to your MIG/TIG videos would be awesome too...
Clear, easy understanding, well-done !!!!!
Great video, Bob!!
Haha thanks!
Clean as a whistle.
Great
You the Man Bob! (also thanks to your doggy...)
Thanks great vid bob
really a great video, it helped me a lot about, can you please make a video about direction of flow of current and its consequences in arc welding types
Great work On internet so far
I just discovered your videos. Very good! Love the graphics! Information is great. I have been looking for something like this to include in some online courses I hope to use for augmenting my face to face classes. Starting one tomorrow.
Great! Good luck with your class.
Thanks
خیلی آموزنده و عالیست
Hi bob!!
Just get in this channel..
And watched one video then another then all..
Great job..
From explanation to graphics presentation so nicely done... Anyone can understand easily...
Hope you can upload stick welding soon..
And other related video regarding which type of material required which type of welding..
Thank you😊
You are too kind, Mehul! Glad you enjoyed them. We are working on a flux core video and then stick welding is next.
Hiii, thank you very much for your video it helped a lot. Could you please talk a little about the HAZ specially for MIG and TIG? l want to know why the size of HAZ for MIG is smaller than TGI's please.
Thank you bob.
You are welcome!
Great videos. I'm going to show them all to my kids. They have been bugging me something bad to learn how to use my everlast welder. I want to make sure they learn about the welder's internals as well as how to weld.
Great!!
Thx a lot. I am so cunfused regarding influence of DC polarity to weld penetration. So what is better fo more penetration on base metal? DCEP or DCEN? And why? And is is the for all welding processes? Will be happy to get a proper answer.
Good content
We want more videos on weld...Plz sir upload more videos on types of welding
hi bob, i am new fans from indonesia. thanks for sharing. But sadly why you stop sharing and not making another content. Keep it up dude
How to determine the direction of welding electrode in MIG welding
Amazing, Bob! But there were some points in the video which I didn't understand well and had to rewatch the video and look them up on Google. Also, there are some glitches in your illustrations, sometimes video is not synced with your voice and other times various unwanted things like cursor, drop down menu or white bars appear randomly. Overall, I liked this video as it simplifies the welding methods you explained and gives a general idea of what they are. Nice job on drawings and diagrams! I guess if you could also make a series of videos on various systems of cars, airplanes, etc they will become very popular! There are many cool ideas for making videos. Your channel HAS the potential to become much more popular. Keep up the nice work ;)
Thanks, Sepp! I know we kind of got in a hurry with this one. Sparky was really excited to talk about welding, so we imposed a short deadline on ourselves. We'll try to slow down and improve the quality in the future! We LOVE your feedback!
No problem! By the way, it sounds like Sparky has something to do with electricity! Maybe he has topics to talk about in the field of electrical engineering as well! Can't wait for them ;)

Hi, Bob. I know some people close their eyes while welding without wearing a mask or a helmet.
Is that a dangerous thing to do? What are the health hazards or side effects of it?
Golly, Shepp -- that's not recommended at all. There is a lot of UV coming out of the arc. That's going to burn their skin if nothing else. Also, the hood helps protect against flying spatter and sparks. You see it done sometimes -- especially when people are tacking an assembly together -- but that doesn't mean it's a "best practice." Also, welding without looking tends to produce some pretty lousy joints.
I know folks will say "I've done this for ___ years and I've never gotten hurt," but that argument doesn't really hold water. I try to err on the side of caution.
Thanks for the question!
Thanks a lot! A user claimed on Quora that UV can even reach the retina through eyelids. I don't know if that's true but it sounds very scary!
Are you a teacher or something these are good!
