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. “How to strike and arc & restart” ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-mEYgYhDd3-Q.htmlsi=ltJ_luX78MPrVi6S
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.
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.
@@lawsen3719 I say the earlier the better im still in school right now about to graduate in 2-3 months so far im liking it. After my school im going to refineries with my dad which is not bad making 51$ an hr plus 120$ a day for per diem and travel pay and refineries aren’t like pipeline which you’ll always out on the open field
Very much enjoying your teaching style here. You're making a lot of great points that I haven't seen on other welding videos, and writing the pattern for the electrode tip on the piece (like the "G") is worth a thousand words.
That’s what it’s all about, brother. I pray that I say the right words, show a certain technique or angle that could help even one person. I’m happy to hear this helped you in some way. I will continue to post more videos. My next one is explaining a few ways of preventing undercut and how your puddle controls your speed! What do you think? Anything comes to mind? Have a blessed one. LET IT SHINE!
@@letitshinewelding3787 As an amateur I'm not the fellow to be suggesting topics to you, but that sounds like an interesting one. I think it's a bit unfortunate that style trumps substance a lot on youtube, but I'd just say to do your videos in a way that pleases yourself, and not compromise your personal style.
Your correct. I my instructor saw I was favoring Tig, so I spent my first year trying everything ,and my last year in the Tig booth. He had me welding aluminum boat parts for the Marine shop in our school. Right after school I got a job welding for a major airlines on titanium. It was easy to switch over, because all their machines were setup correctly for the type of parts they wanted me to weld. I just sat down . and started welding, in an air conditioned shop making big money too.
I learned a lot from this video, Thanks so much for making and sharing it! I’m stuck on 1G at the moment but my class is doing all this pipe fitting, hand beveling and welding up pipe, some even further along than that. I have to work on my tie ins and figure out how not to have so much metal buildup at the bottom of my plate, keyhole issues etc , all the beginner mistakes, but my notebook came out at 11:00 minutes mark and It was speaking directly to my issues i feel! Gonna try it out and see if it applies to my 1G with no back strap. You covered 2 weeks of schooling in 30 mins 💪🏽. I can always look back on this video when I get there. So blessed to have come across your channel! 🙏🏽 You’re an amazing teacher by using mistakes you’ve seen others make and by thoroughly addressing how to do things in detail which I feel a lot of great welders don’t do because they’re so good they forgot how beginners think and understand stuff. Please keep making these videos 🙏🏽👏🏽, You’re amazing! 💯🤙🏽💎 God Bless Brother!
