    Great tips! Will need to work on this to improve my welding.

    Hey man, would you recommend going to welding school for a 20 year old? I'm in college right now (with no debt because college is cheap where I'm from) but its going to take me 10 years to get a degree. I'm thinking of doing a trade job either permanently or just while studying. I think it takes a few months to get a welding license or degree where I am.
    Is welding a good career that you would recommend? or should I just stick to college and get a degree.

      You can never go wrong doing welding there various ways and types and fields which would fit to anyone

      @@LouHemi Thank you for the thoughts. I'm gonna think it over until the year ends and before my next semester starts.

      Thanks for reaching out.
      I’ve seen students from 17 to 60+ years old! I started welding after high school. Very HOT, in the shop or outside, in Texas! I also went to college while welding & got my associates of applied science in welding.
      If you don’t mind the heat, sweating, working with your hands then welding might be something to look into.
      Different processes to learn which could land you in an air conditioned shop! Like stainless, chromium, aluminum or other exotic metals.
      Not sure what degree you are going for or what part of the country you’re in? Some schools or welding training offer short courses like 2or 9 months. Which is enough time to learn one processes (TIG, Stick, MIG) which could land you a job while you continue school.
      I’ve enjoyed my career in welding. I’ve also wanted to do it since I discovered it in high school & stuck with it.
      Welding is & always will be a trade in need! Maybe try welding engineering or technician?
      Best of luck, thank you for your time.

    I think overall this happens if you don't prep your metal properly. Am I right?

      Correct, light mil scale and rust makes a bad difference from a clean or questionable weld.

    i gotta question boss, i'm on 1g and i'm having problem with porosity with 7018. I'm only getting porosity when I start the line in the very beginning and not anywhere else. What is the cause of this problem? my instructor is telling me to hit the arc and hover outside of the plate for a second and then come into the plate and build the puddle and start the line, is this the only way?

      Great question. With 7018 the flux plays a huge part with porosity. We have one clean start with 7018 which is the first strike of the arc. If you have a clean start 90% of the time you will have a good start to the weld with no porosity.
      Porosity happens when we don’t have a clean start. If you get stuck on the first or multiple tries get the grinder and clean out the arc marks & then restart.
      The electrode needs to be showing metal at the tip but with plenty of flux covering it. If it’s too long of a metal peace, even an 1/8” without flux porosity will happen 99% of the time. I believe your instructor was referring to that, if that’s the case then hold it off to the edge of the metal and let the electrode fully inflame and then bring it down to the 1/8” - 1/16” arc length and start your weld.
      I do a flicking technique with my 7018 so I won’t have to break through the hard flux when trying to restart. I’ve attached a link to one of my other videos that shows that and more. Doesn’t talk about porosity but it can help with it and few other things.
