Welding basics

Recommended Posts

welding is of course a process that joins 2 separate pieces of metal. Modern welding machines come in a few different flavors.

SMAW (Shielded Metal Arc Welding a.k.a. stick welding) consists of a welding machine with a grounding clamp cable, an electrode holder cable and a steady supply of electrodes (foot long metal sticks that are coated in what is called flux). This is a very common type of welder and your gonna pretty much going to find one any where metal work is being done.(this type is also very common on farms)

A few notes about this type

-you can run these machines of generators (in fact i think some models come with generators attached)

-welds produced are pretty strong but not very pretty lol

-electrodes that this machine NEEDS to weld do have a shelf life, but that depends if they are stored properly or not.

 

GMAW (Gas Metal Arc Welding a.k.a. MIG) like stick you have a ground clamp cable but instead of a electrode holder you have a wire feeding welding gun. This setup also requires a tank of inert gas to shield the electrode wire while welding. This set up is also very common but your only gonna find this in larger metal shops.

A few notes about this type

-Technically you can run this type of a portable generator but I have never seen one set up like that.

-welds produced are typically not as strong as stick but look way nicer

-unlike stick I am pretty sure the filler wire coils or inert gas used don't have a shelf life but unless you stock pile the gas (extremely unlikely) MIG's gonna be useless after you run out.

 

GTAW (Gas Tungsten Arc Welding a.k.a. TIG) This one is a bit more like soldering, like the MIG you have an inert gas shielding the weld but unlike MIG the TIG welding gun does not feed the filler wire you instead hold the wire in your other hand (kinda like soldering)

A few notes

-like MIG once you run out of inert gas your done

-used mainly for welding Aluminum, Copper, and thin pieces of metal

 

If you are looking to getting into welding my suggestion is to get a Stick welder you can go to a metal supply shop or farm coop store and get everything you need in one go.

 

Safety

Always make sure you use a proper welding helmet preferably with #11 shades and safety glasses, leather gloves (i prefer HEAVY welding gloves),some sort of cap made of cotton, a leather welding apron or a starched cotton shirt, Jeans and CLOSED TOE SHOES!!

 

Instruction

Before you begin I would highly suggest getting formal instruction, you can probably find some classes at a welding supply shop. If you have a friend who is a professional welder have them show you the ropes (I learned at my Dads fab shop when I was 15 or so). Welding classes aren't too terribly intense, I have personally found welding easy in it's understanding and technique but difficult to master (i.e. its all about practice).

    • This is a great inspiring article. I am pretty much pleased with your good work. You put really very helpful information.

    • Hey all, This is sort of cool (okay really cool) and maybe some of you have heard about it because it's been plastered over FOX and mentioned by POTUS as well as other conservative-leaning news people (Huckabee, Diamond/Silk, Candace Owens, Mark Levin, etc..) and politicians. #walkaway is a movement based mostly on social media. Started last year, by Brandon Straka (pronounced Strawk - like "straw" with a "k"). He's a former 2016 HRC-voting hair stylist, from NE, now in NYC, homosexual, liberal who began to question the MSM and what he was hearing. He got really frustrated as he began to do his own research. Anyway, after having his own awakening to the lies of MSM he had been following, he began an online testimonial campaign in which former liberals can post their #walkaway stories, written or video. Many are now on the "Trump Train." Many have simply left the Left. Still, others have always been non-Left and are members in support. The amazing thing is how many different people from all walks of life are beginning to wake up. Lots are not conservative on all issues, but all have a love for the USA and dislike the demonization of open political and social thinkers and speakers. This group gives solace to people scared to voice their conservative opinions or views for fear of negative professional or personal responses. It now has budding smaller groups in all 50 states and an online discussion group where people discuss current topics or issues (WITH no vitriol, gasp).  Here's the original video from Brandon.  www.youtube.com/watch?v=51UGcghHZsk This man, Brandon has a unique, stylish, well-articulated voice to help move people "in hiding" out into the open and not be silenced. Pretty much any video Brandon does is great. Here is the Facebook page: www.facebook.com/groups/OFFICIALwalkawaycampaign/ As I see fights erupt online, I simply leave #walkaway in the comments. Brandon has a goal of 1 million members! The liberal media has called this campaign "Russian Bots" and "paid actors." It's not!!!        
    • thanks to all who  have served or are serving our great country....243 years in the making....   Trump did a good job today thanking each branch of our military and a long time coming salute to the coast guard too....
    • I can imagine food prices going up this Fall or Winter. Corn is used for live stock feed, & us humans consume a lot of corn based products, as well as corn based biofuel. I’ve been keeping a watchful eye on the mid-west of America, which is flooded by water. Where corn  & other crops are normally grown there. Farmers are quite worried about this years growing season. Time to stock up on extra food if you can, if you haven’t already. Stack it high, stack it deep. Store the foods that you normally eat. What ever the  amount of food you’ve stored,  try to double it if possible. Better extra safe, than sorry.
