I've been certified since 1981, welded on Trident subs for Electric Boat, have worked multiple nuclear power plants, bridges, buildings and some ornamental stuff. SMAW (stick), GMAW (mig) and GTAW (tig), some brazing on steel, stainless and aluminum. I've even done plastic welding on large acid baths made of thick sheets of poly that had to be fabricated on location. There's a huge amount of information online these days to learn welding techniques that were not available to my generation. One thing I can say, I like your presentation, the information is spot on and really helps to make it simple to new welders what to look for. My mantra: puddle control at all times. Carry on, you're doing a great service.

Im back watching this video for the 3rd or 4th time because I'm trying to correct some basic faults (a self taught welding starter).
The fact that Im here and not going to one of the hundred or so video welding tutorials I have watched says it all.
Thanks!

Thank you for another informative video. Can you make one that breaks down how the puddle(close up) should look like while stick welding?

[habertamoti]

Thank you Mr Tim. I need notes if it is possible.

[slavnyan]

Hi. I absolutely love your videos. I'm intrested in welding and recently my uni sponsored a (TIG / MAG) course, which I will attend, so gathering im gathering some knowledge.
I would like to have request if possible. Could you make a video about welding mascs, as i can't find any on your channel?

[davewallace]

Aluminum is classed as 'hot short' as soon as it is heated it kinda waters it down, and if no filler is applied the weld becomes brittle and weak. I've seen many running perfect beads using TIG but used no filler, and if those welds were to be put into service, they'd fail almost instantly. Nice presentation, I like it.

[joecolletti]

Nice job :). I knew nothing about welding, but clicked because I'm interested. Your "4 types of welding" video and this one were really clear overviews...makes me want to find a local class and get hands on. Thanks Tim!
