Why is it good for welders to drink milk ?
I heard welders should drink milk as it adds in the absorption of , I think, magnesium, but I am unsure. Or maybe it is a tradition. If you know, kindly reply. Thanks.
Question answered by Father Ted
Milk is used to absorb the metals breathed in from
welding that cause metal fume sickness,
blindness and othere sickness.
Fumes from zinc oxide (ZnO) or magnesium oxide (MgO), often through breathing fumes created by heating or
welding certain metals, such as galvanized steel
cause Metal fume fever.
The symptoms are nonspecific but are generally flu
like including: Fever, chills, nausea, headache,
fatigue, muscle aches, and joint pains. A sweet or
metallic taste in the mouth which distorts the
taste of food and cigarettes is also normally
reported along with a dry or irritated throat which
may lead to hoarseness. Symptoms may also include a
burning sensation in the body, shock, no urine
output, collapse, convulsions, shortness of breath,
yellow eyes or yellow skin, rash, vomiting, watery
or bloody diarrhea or low blood pressure, which
require prompt medical attention
Milk is highly regarded by experienced welders as
effective treatment for absorbing the metals that
accumulate in the body. It is best to drink milk
before the onset of symptoms.
For experienced welders what are the different types of welders?
My husband wants to buy a welder for himself and we both want to learn how to weld. What are the different types of welders and what are the differences (I think TIG, MIG and Arc, but I'm not sure) and what would be the best one for a first time welder to learn on. And, if you have one what brand do you recommed (our budget is about $500). Thanks for all the help.
Question answered by tinkertailorcandlestickmaker
It depends a lot on what you want to do, will this be for crafts/sculpture or for more structural applications (perhaps building a trailer or something) will you be welding only steel, or would you like to weld other metals? For your price range, probably MIG will be a pretty good choice, but with a low cost machine you are pretty much limited to steel (that can include stainless), cheap machines don't feed aluminum wire well,. If you are doing sculpture of other work where bead appearance is important, you'll probably want to get a machine that uses shielding gas. A lot of cheap machines are sold as "glassless" and use a flux core wire, flux core does work well, but there is quite a bit of spatter and smoke, gas shielded is cleaner. By the way, MIG stands for Metal Inert Gas, the acronym for flux core escapes me at the moment, but you may find that on low cost import machines they are inconsistent with terms anyway.
Personally I'd prefer a TIG/stick welder which would enable welding virtually any weldable metal (most "TIG" machines will do stick too, which is faster for heavy work in steel) but in your price range you have to get a no-name import for TIG, and I hesitate to recommend no-name machine. I have a Lincoln, Miller is good too, but for a TIG you'd be looking at at least twice your budget. However name brand, low power MIG machines are available in your price range.
How do welders put out so much power?
It seems to me that many welders claim to be outputting 120v at 100A. I understand they dont have 100% duty cycles, but how are you getting 100A out when you put 15A max in? Thanks in advance.
Question answered by lee26loo，異地強秦後人
Wrong ! Most home welder runs on 240V 30A input power. Output is about 35v to 70v at 50A to 75A adjustable.
Which welders are the best and the quietest?
My Dad is a welder and he has a welder, but it is really loud and he is starting to have hearing problems. So he is looking to get a quieter one, but I don't know which ones would not be so loud. Any welders have any suggestions?
Question answered by robbie798
I have a 1991 Lincoln SA-200 it was quite loud before I built a muffler for it. Now it's not bad at all. Lincoln also makes a welder called a Vantage which is very quiet. I would suggest that the cause of your fathers hearing problems are not the welder but the grinders and hammers used by weldors all the time. I have been in the industry for over 25 years and speak from experience. You asked about the best welders and that is definitely Lincoln, but quietest is a matter of your own perception.
What kind of welder should I buy for welding angle iron?
Im planning on welding trailer frames, i would like to be able to weld thicker metal later, i was looking at ark and mig welders, and i wanted to know how many amps and volts to get. I will be welding 1/8" to 3/16" angle iron i think, i don't really know yet.
Question answered by re2345
get an arc welder that has at least 200 amps dc
a name brand such as lincoln miller etc
practice with the 6013
switch to 7018 for higher strength
mig welds are strong but brittle they will break without warning if overloaded
and yes i know a lot of shops use the mig on everything
but if they see what i see all of the time they wouldn,t
arc welds will usually start cracking before they fail
on the lighter metals you are talking about the mig would be ok or if you plan to do any aluminum welding
but if you want to go to heavier metal later the arc welder is better
most of my welding is done on 3/4 inch or thicker metal
i will use my mig if it is nonstructural
if you think what i say about a mig is not true try fillet welds on 1/4 inch plate then bend them
The difference between where airman are stationed and air force mechanic and welders?
I'm a future USAF wife and i was wondering if there is a difference between where airman and the AF mechanics and welders are stationed? I'm trying trying to get a fill for what i'm in store for in a few months.
Question answered by Greco
Well first of all, all enlisted personnel are airmen. E-1 is the first rank you have and that is called airman basic and E-2 is airman etc. but anyway they are usually still in basic training at Lackland AFB and in tech school wherever they go to train for their jobs. Auto mechanics and welders would be stationed about anywhere and aircraft mechanics would only be stationed at bases with aircraft.
Here's some things for you to read. The one site you have to register for, but it has all sorts of info for military spouses. The other ones are just to look over and give you some idea of what things are like and look like.
I think you meant you wanted to get a feel of what it's like. I think I gave you a fill.
In western Pennsylvania what is most needed, gas welders or arc welders, or is it mostly even?
I'm interested in getting a qualification in welding due to the rise in the demand for qualified welders here in Pennsylvania. I'm just curious about which course might be a better choice, and any information in general would be appreciated.
Question answered by Man-eating WOMBAT
By "gas welding" I assume you mean "Oxy-Acetylene Welding." or OAW.
OAW is a completely obsolete process, but it does have some use as a teaching tool. I'm not aware that anybody uses it commercially any more, at least for welding.
Arc welding processes make welds both faster and of much better quality than OAW. Sometimes oxy-acetylene is used commercially for "brazing" and "soldering." these are not the same as true welding. Brazing is isn't very common but it does have some niche applications. If you're a welder it's helpful to know how to do it, but probably won't be a major job requirement
The three most common welding processes used in the US are, in order of importance:
-MIG Welding, (a.k.a. gas metal arc welding or GMAW)
-Flux-Core Arc Welding a.k.a. "Dual Shield"
MIG welding is almost universal; it's fast, cheap, and effective. MIG welding is very easy to learn but IMO difficult to master. The key to truly mastering MIG welding is knowing how and where to set your voltage and wire feed speed, based on the thickness of the material you're welding, and that takes a few years of experience.
Dual Shield is used a lot in heavy steel fabrication. It's very similar to MIG, and uses the same equipment, but the welding performance and techniques used when you're welding are a bit different.
TIG welding is the most difficult kind of welding, generally. If you have some good skills with TIG you can make some very decent money as a welder. Most welders learn to do TIG welding last, because it requires a certain amount of "welding instincts and reflexes" that you develop over time with other processes. It would be difficult to learn to TIG weld correctly without having some prior welding skills and experience.
Less common than the former three is Shielded Metal Arc Welding (SMAW) which is a.k.a. "stick welding" by most welders. Old-timer welders also call it just "arc welding" but this is confusing because all the former three processes use an arc as well.
Stick welding is useful for welding and weld repairs in remote areas off-the-grid. Sometimes it used for on-site steel construction outdoors, but that's slowly being replaced by other processes. which are faster. Stick welding has no place in an indoor shop environment. it's slow and doesn't produce quite as good quality as the former three. If you see a company still using stick welding indoors, you probably shouldn't apply at that company, because it's a company that doesn't care about it's welds, IMO
If you want to spend your work days welding outdoors every day, then learn how to stick weld. Stick welding is also very useful as a teaching tool.
What are some eye drops for welders flash?
My husband has redness in his eyes we tried the potato and it worked a little. What are some eye drops I can get for welders flash?
I am trying to find something at the pharmacy?
Question answered by yagman
There really is nothing available in an over the counter non prescription drop. There is a very effective drop called Acular that decreases pain sensation and also decreases inflammation. It is quite effective in improving the symptoms associated with welder's keratitis. It is only available as a prescription, though, so you must see a doctor to have it prescribed.
How to become a welder as a career?
My teacher told me welders make around $100,000 a year and there is a high demand for them. I have experience welding in my high school program and it appears to be an moderate job that you have to have precision and endurance for. If you are one explain to me what you do exactly and the hours you work.
Question answered by Daniel
Honestly a trade school will teach you enough to get yourself in trouble. Yes, they will teach you the basics of how to run a bead in which ever process they have at the school but that is just a controlled environment. Welding product in a shop or in the field is much more intricate than anything you will learn in in a school. I am not saying that school is bad by any means. It will get you off the ground but only like 1", per say. A welding career takes time, patients and tons of experience. I would advise you to nab a job as a welder's helper or fitter's helper. Go to to school at night and slowly work your way up. As you progress you can easily make great money. Do not even think you will just bust out making the big bucks right off the bat. That's just silly. Don't let your ear overflow with too much honey. The job is beyond hard. YOU WILL work extremely long hours and YOU WILL get burned, cut, beat up and whooped. It is no walk in the park by any means. I wish you luck in this crazy world we welders work in.
What is the difference between TIG, stick, and arc welders?
What is the difference between TIG, stick, and arch welders? My boyfriend is wanting to learn how to weld. What kind of welder should he buy?
Paranormal Investigator in Ohio
Question answered by ChevyGuy
Here are some basics
Gas Tungsten Arc Welding (GTAW) is frequently referred to as TIG welding
benefits:Superior quality welds
Welds can be made with or without filler metal
Precise control of welding variables
Free of spatter
A Mig welder is a wire welder with a mig outfit it uses a sheilding gas mig is also know as Gas Metal Arc Welding (GMAW) most robotic welder are mig and they are easy to use
Benefits:All position capability
Higher deposition rates than SMAW
Less operator skill required
Long welds can be made without starts and stops
Minimal post weld cleaning is required
Stick welding and arc welding are the same
Shielded Metal Arc Welding (SMAW) is frequently referred to as stick or covered electrode welding. Stick welding is among the most widely used welding processes.
the only down side is it makes so much heat that it makes the metal brittle
benefits:Equipment used is simple, inexpensive, and portable
Electrode provides and regulates its own flux
Lower sensitivity to wind and drafts than gas shielded welding processes
All position capability
downside is it makes the metal brittle, its porious, cracks, and produces alot of slag
I highly suggest a MIG welder or just a plain wire welder very easy to use not that cheap you can get a good Lincoln for a few hundred
And i suggest a lincoln over a Miller
