You can learn to weld. I'll show you exactly what to do in my affordable online welding courses at courses.timwelds.com.
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.
I done a acid room one time and I was never so glad to be done with that, I can't remember now if it was 1/4 or 3/8s but I remember it taking a dick yr! We custom made a galvanize plant to dip hog flooring so we didn't have to keep sending it to IL to have it done, our galvanize was was better and looked alot better with a few rolls of aluminum foil melted into the tank of liquid zinc.....oh the good ol dayt, lol
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 so much!
i work as a daily mig welder on structures , the explanation of welding of this its very very precise and concising , absoluty well explained and with out making it very long , Congratulations man those are perfect examples of welding ploblems and his reazons ,very well resolved and explained ,CONGRATS FINALLY A GOOD VIDEO OF WELDING PROBLEM SOLVING !! , amazing content, new subscriber over here 👍👍👍
I have been looking for information on mig welding defects and how to correct them. I've learned something from this. Thanks Tim👍
Good indepth info for me, as I'm self taught and your videos are really helping me visualize were I need improvement.
Great Tim. Very good examples. You are the guy I send beginning welders to.
Really Great and well explained information. Thanks Tim!!!
i like the way you explain things!! Its very clear and understandable.!.thanks.
Great information. I have a feeling I am going to be returning to this video a lot.
Good, succinct, clear, detailed - thanks!
Good! I like the examples of things to look out for.
Thank you for sharing your knowledge and experience. I’ve always wanted to learn how to weld and I’m slowly getting there. (Not as easy as it looks, huh?) 🤪
A wealth of useful information Thank You !
Tim I like the way you teach techniques. I am enjoying your videos. I’m fairly new to welding and I’m learning quite a few tips from you. I really appreciate that. You do this for people like me. Hope you had a great Thanksgiving. Take care. Erick Phoenix, Arizona
Thanks man . I like your information you are the best ,😍😍😍
Thank you for another informative video. Can you make one that breaks down how the puddle(close up) should look like while stick welding?
I'll put that on the list. I have some better equipment for arc shots now than I did when making most of my stick videos. Thanks for the suggestion!
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!
Thank you Mr Tim. I need notes if it is possible.
Great stuff!
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?
Good job
My high school has a separate career tech building for all types of stuff, milling, construction, welding, auto, you can also get certified for solid works and a lot of other software
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.
What nobody ever seems to explain and what I still don't understand is WHY the weld profile is bad. Is it just unsightly? Is it a functional weld with too much extra material on top, or is it structurally compromised?
Thank you.
a nice video to do would be one on doing a vertical stringers on the mig on thick plate
Thank you :)
Hey Tim, do you have a video about welding gloves and other protective clothing? Why are some gloves specifically defined as 'Argon' welding gloves? thx
Perfect weld.
Spot on. Fish eyes on aluminum is like Snake eyes in craps, generally bad!
Hey Tim, looking to purchase a mig welder for auto body and misc jobs like wrought iron fencing project that I’m going to start. Which make and model do you recommend?
im welding concrete rods that have anti rust treaement and using mig nogas it created huges bubbles i brushed the rods before with steel but this treatement seem to be electrorlytic or such deep impossible to remove
I've seen almost all these welds on tools from harbor freight.
Nice tip about groove welding that will stick with me - If you want full penetration, focus on the bottom body
Hi, i have a porosity problem exactly like the middle weld. What cfm should the regulator be set at? It's a 110v miller mig
What respiratory do you use please?
Hello, thank you for your informative Videos. I have a question: I am thinking of buying a (low budget) welder. I am total beginner; im just thinking of some DIY projects (maybe like a fire pit or a smoker, maybe little things for inside the house; this kind of stuff. Aluminum ? ... don't know yet). What would you recommend? first idea: Stick welder. But maybe also MIG; maybe first used with flux core? Or do you think a DIY person could self taught learn TIG? If it is not overly expensive, Id like to be a little future proof, if that makes sense. For the time being, I only have one phase current available at my house (which is 230V in Germany). Can I expect acceptable examples on this or do I need 3phase (400V in Germany). Thanks for your input.
In my humble opinion stick is the best to start with it's cheaper and easy to set up for a beginner and your not dealing with gas or wire just rods. You don't need to spend to much 1-2 hundred euro will be plenty good enough as long as it can do 100 -150 it will be enough for 99% of jobs
What am i doing wrong if my mig weld comes out super black? My gas is working and I'm keeping my gun close to the weld. Thanks
Im welding on a trailer. Im having no luck welding the bottom side of the beams. Ive got an old Powermate 100 and im welding 3/16 steel. Welder says heat should be at 8-9 and wire speed at 6. It just spits and sputters. Slightly slower wire speed and it just hisses and never gets going. Slightly faster and the eire just bounces off the iron. I can’t adjust gas flow and I have a full tank.
Is penetration needed when welding??? Idk if i want to weld anymore
One of the most common issues for porosity, is the welder failing to clean spatter and build up from inside the nozzle. The first thing I check when someone comes up to me asking why they’re getting porosity is usually due to this. Second most common is welding on contaminated surfaces. Grease, oil, dirt, rust or even too much anti-spatter
If is a dirt pipe inside that you cannot have access to clean or grind? I believe that these youtube tutorials should cover these real-world scenarios. These are challenging welds that several beginners will face. Weld a fresh and clean both sides steel plate, I made good weld from my first day. This is a dream condition for any welder.
Hi Tim. What is the best solution to avoid inhaling the fumes of burning rods without causing porosity and without a respirator mask? I was planning to blow away the fumes with a soft blowing fan, but now I don't know what I'll do. Wearing a respirator mask is an option, but sometimes it's just too hot and very uncomfortable. Please share advice about this :)
If you are stick or flux core welding, which produce the most fumes, the fan won’t cause porosity because the flux will protect the weld on site. With MIG or TIG, you won’t have as many fumes, but you can probably still get away with a fan blowing away. If you find you’re getting porosity, you can increase the gas flow a little or reposition the fan.
@@TimWelds Thank you Tim. 😁 I'm a beginner with stick welding. Fumes are very nasty, I'll try to blow them away from my nostrils with a fan and exhaust them with an extractor. It will look like an luxurious shop. Ha. Because no welder in my whole province does this. They sniff it all in. Dumb thing to do. Haha. I like comfort and safety.
OSHA guy here please wear a respirator. You have a lot of options, there's even COOL version I forget the name that stays cooler than most. Search cool air respirator
@@MrArtVein A blower and an air extractor is not enough? 😱 What number of respirator filter?
Don´t bogart this joint my friend!
Hi when I try a weld I get 1/2 on one side and 1/2 on the other just slage inthe midle what am I doing rong
I assume you’re running a stick weld with 6013 rod, which commonly has this problem. If that’s the case, you probably need more amperage. A different type of electrode, like 7018 might make life easier too.
@@TimWelds I have the same problem and I am welding thin plate (14 gage), so I can't really go up in amperage. I'm using 6013 rod, 5/64" in size. I'll run another few tests and if I can't get away with it, I guess I'll have to use another type of rod. Any advise is welcome...
Push or pull ?
I can’t tell if he’s trying to flex his fire extinguisher
I don't know why..but I weld stick weld so good from all angles..but I weld mig like shit..It just doesn't make sense for me this machine..only the horizontal welds are looking good
If your technique is working in the horizontal position, my guess is that your settings (both wire speed and voltage) are too high. The recommended and automatic settings from most manufacturers (especially Miller) are really hot and won’t work in all positions. I would try the settings for 1 or 2 material thicknesses thinner than you are running when you are working out of position.
Hey... welcome to the shaaaapppp. LMAO.
How do yall Weld a 2nd and 3rd pass and still keep a straight line? Lol
My welds look like they were done by Stevie Wonder.
Stick welding is too hard I put the machine back in the barn
