    welding tips

    i think some "welding tips" will be an excellent thread to start on here! maybe someone already done this, and i just couldn't find it. looking through many builds on this site, i've seen everything from absolutely beautiful welds....to "bird crap" welds. to start this, i'll let everyone know that i am a "self taught" welder(so, i'm not saying my welds are the greatest welds i've seen)! now, my job is a welder/fabricator with a trucking company. so here are a few mig welding tips i'll start with.....#1: get the welder set(many welders have good starting points listed for the thickness of metal you will be using). if you don't have a chart to start with, use some scrap metal and experiment with different heat settings and adjust your wire feed to find what works the best. after a while, you'll be able to adjust by the "buzzing" sound you hear. many things can affect what settings work best for different people(one example: how close you have the nozzle to your work piece) #2: i like to watch the "puddle" as i move along. it is easy to "undercut" your weld if you aren't paying attention to the "puddle". an "undercut" area WILL be a weak spot, so try to avoid doing this.

    Dusty, i agree, great topic. I started a similar titled titled " https://www.minibuggy.net/forum/proje...ild-buggy.html ". Also the rorty website has some great pictures of problem welds. My advice..... if you think welding is like gluing pieces together, its probably being done wrong

    Yeah,
    I got a tip.

    DON'T BUY A FLUX CORE ONLY WELDER.

    Truth is its not bad, but welding splattering clean up is worth 50 or 100 more bucks NOT to have to do it.

    I was on tight budget when I bought welder brand new from Tractor Supply. Hobart is good enough for me, but if I had it to do over, I'd of purchased a welder that uses shielding gas. I know as well as any, you gotta do what you gotta do.

    yeah, i agree! many of the inexpensive welders come set up with flux core wire, but some can be converted to gas. if i remember correctly on my hobart 130, i just needed to switch the polarity, get the bottle of gas, and a spool of wire. it was set up for flux core(and came with a very small spool of flux core wire), but it came with the hose and regulator to use with gas. and i lucked into a FREE argon/co2 mix bottle!!!

    I personally see no reason to spot or pulse weld anything other than sheet metal, you are better off with a consistent flow. You can achieve a perfectly decent looking, and faster mig weld without it.....

    A few I did last week on a chassis, and i'm not what i'd consider a pro even though I do a lot of welding daily....

    yoshi, i agree! the only time i've used pulse welding, is too reduce warpage when replacing body panels. in reality, everything could be tig welded.....but it is a much slower process! one of the big advantages of mig welding....is the fact that it is fast! and even though i weld for a living(tig, mig, and arc). i also do not consider myself a pro, as i am "self taught"
    however, "there is more than one way to skin a cat"! So, i'm not saying the way i do ANYTHING, is the best way, or even the right way! i just thought this would be a good subject (that many people would have ideas, and advise) to help those who don't feel comfortable with their welding skills???
