Welding Topics to Learn About

[BrokenTrack]

As most of you know, I am a welding instructor, and with these current times, we must do everything by Long Distant Learning means. We do that through the book curriculum, but also videos.

In regards to the latter, I have broken my videos down into (2) different categories; Basic Welding Instruction, and Master Class. The former is pretty self-explanatory, but the latter is about what it takes to be a First Class Welder. That is not really stuff that a person would be expected to know right out of welding school, however, by knowing something about it, they might rise to first class welding status faster.

So far I have done the following videos:

Basic:

My Biography as a Welder
Starting an Arc with Previously Used Rod
Understanding Duty Cycle
Where to Weld and Not (weld placement)
Welding Electric Shock Safety
Welding Eye Safety
Welding Hoods Explained
DC versus AC Welding

Master Class:

Pulsed Welding
Mirror Welding

I have been thinking about doing the following as well:

Basic:

Basic Electricity
Welding Smoke
Welding Rod Types
Good Habits of Welding
10 tips to be a Better Welder

Master Class:

Minimizing Grinding
First Class Cutting Torch Work
Understanding Three Phase Power
Merits of being a Humble Welder
Welding Cast Iron

Can anyone think of other topics to do videos on?

With so many welding videos out there already (some good-some bad) it may be hard to find subject not covered....

BUT one thing that seems to be lacking is "seeing" your "weld".... I mean like adding a headlamp on helmet to add more illumination for weld path, adding magnifying lenses to hoods, looking at arc/puddle from side of MIG torch instead over top to see what the puddle is actually doing, maybe getting cataract surgery for old eyes....

All things that help my 75 year old eyes and improves my welding.... Subject has been introduced some what a while back in "Weld Talk" the Hobart site but there does not seem to be any real coverage on subject...

Another safety one - respirators and welding fumes - stick, galvanized, Stainless (hex chrome)...

Adding an LED spot light to my helmet is something I would really like to try. Might have to see if I can easily mount my camping LED headlamp to my helmet.

A friend of ours buried her husband a few years back, welding was his profession ... the fumes eventually killed him.

IIRC, he was maybe around 60 ...

Welding was part of my former pipefitting trade and I was ASME certified for power piping and pressure vessels. I avoided hiring out as a "welder" to avoid breathing all that smoke and the eye strain. Always asked for a fitter position first; but the welding skills kept me on a job longer and fitters were moved up to foreman more often. Until you try welding with a respirator you will understand why they lay in the gang box, along with the heavy full leathers the safety code requires. They were pretty much a must when welding galvanized or other metallic coatings. An exhauster close to the work was usually the best solution except MIG, sucked all the shield gas away. We even used vacuum cleaners with the bags removed to prevent fire from sparks. There are now in hood air supplies that look pretty good. My intermittent welding now doesn't justify the cost. I have lived much longer than most of the guys that were "welders" at the trade. Of course most of them were also smokers and I never have been.

Bless you Ron... you inhaled enough unintentionally. Unfortunately too many people in the trades have been unknowingly exposed to harmful fumes and materials until somewhat recently.

Can you get sunburn from welding? I did a big job yesterday in tshirt, shorts, flipflops, welding gloves and helmet. The insides of my arms from my tshirt to my welding gloves are on fire. Last night and tonight. I don't burn easily, I'm in the sun half the day every day and can't remember the last time I got burned, but this hurts.

Absolutely!!!

I have had that happen as welder's fitter working on an aluminum painted roof top. Could not get away from the reflection. Worst case of eye sunburn ever.

I must digress and tell a story from my pipefitter days. I once worked with a old time welder that worked in shorts and a tee shirt arc welding. He was a white guy but his chest, arms and legs were walnut brown and leathery. He had little burn marks all over. He bought a new tee shirt every other day as 2 days welding turned them into swiss cheese (oh,always 100% cotton). The foreman tried everything to get him to wear the leathers he was issued. The main office finally told the foreman "send him back to the hall with reason, insubordination". Last time I ever saw him on a job. Flip side, he was one **** of a welder, perfect work, and high producer.

I don't weld for a living, just side jobs. So i'm a bit free and loose with safety. I'll always wear my helmet though. Learned to weld with the flip down helmets doing stick, and didn't take it very seriously. Welders flash can stick with you for days or more, give you migraines, all around unpleasant. Also helps with fumes, especially now that masks are so hard to get ahold of.

 

[dragoneggs]

I think for some folks starting with MIG vs. stick, can be a little too complacent about safety because of the ease. Teaching safety regardless of method is important. Different materials, finishes, proper clothing, eye and breathing protection, etc. should be paramount. I know in my older age I realize I should have been more careful about a lot of things I did with tools and such. Hopefully I haven't done too much damage over the long term.

Yeah welding smoke is horrific.

I was welding at a shop one time, and unlike the other welders (about 100 welders) there was us (4) that were doing a special job, and using hardwire instead of flux-core. After about a month, we were just talking, and I brought up how I was going to bed early, and suddenly it became apparent in conversation that we were all really tired.

The wire we were using had a lot of magnesium and copper in it, and that was what was causing us to be extremely fatigued and irritable.

Sadly, you look at older welders and almost none have hair. Between the welding smoke and sunlight, it kills hair follicles.

It is no wonder that they predict a shortage of 400,000 welders in the next ten years. But on the flip side, there are not a lot of jobs where you can make 6 figures right out of high school either.

Welding cast iron is a good and useful topic. I壇 include brazing cast iron and also silicon/aluminum bronze tig brazing cast iron.
Also, oxyacetylene welding is considered sort of obsolete but it is a very good way to learn to weld. It is also very versatile and with the right filler and flux you can gas weld aluminum. Not solder or braze aluminum like with those magic pot metal rods they sell at the county fair, but actual welding.

Oh yeh, I got a real good one on my bicep while welding with a t-shirt on. I hold the torch with my left hand, but guide the tip with my right hand (wearing gloves), so my right upper arm was directly facing the arc. I was really surprised how sunburned I got! I have a set of welding sleeves which came with a welding starter pack I bought when I first got my welder, I thought I'd have no use for those sleeves. Now I put one of those on my right arm, it works great.

You might have missed the most important point. FIRE SAFETY regarding welding. A welder destroyed an ENTIRE ICE CREAM PLANT here some time ago!

I am not one to wear much in the summer as I can't stand the heat. I got the worst sunburn of my life once, welding without protection. Arms mostly as I recall!

 

[Industrial Toys]

As far as fire, to me it's a three part process.

1. Assess the risk, possibly move things away from the process. Or move the process.

2. Have appropriate Fire supression means. Several levels, starting with a simple water bucket. STOP and check for fire, or have someone spotting.

3. Do periodic checks of the area AFTER to check for something possibly smouldering.

Stick it on with some Velcro strips as a test before you start drilling holes in helmet.... I am trying a small LED (2 AA cell) flashlight.... Now I need something to weld...

This is why they have welding jackets and suggest you wear pants, and be sure area below helmet (your neck) is also protected.....

Most welders have a magnet with a gooseneck that a small flashlight clamps too. Usually there is something metal to stick the flashlight on, then you can direct the light to what you are welding.

This is what we use in mirror welding, which can be a nightmare. You have to position your mirror just right, then get into the spot and get your light just right. It can be a lot in one spot, then when you can see what you are doing with mirror and light, now you have to remember everything is backwards as you weld. It is harder than you think, try writing your name on a piece of paper using the bathroom mirror.
