- Here is the second part of the weld testing procedures we will be using on the boat. This is a two-part series on trying different welding procedures that are going to be suitable for the boat.
Destructive weld testing is pretty interesting when you can actually see what happens inside your welds. It shows a lot of little things that you can improve on.
Here is a link to the video about the Stringers; • EP50 BOAT REFIT, Engin...
Make sure you give it a like and keep the comments coming. Sheryl and Paul.
We have set up a Ko-fi donation page to help with consumable items such as grinding discs, welding electrodes and any other small items we require to complete the build. We have decided to leave the Patreon program alone at this stage. We will rethink it later in the year. We just don't want that sort of pressure on us just yet. We are attempting to release a video every Saturday morning at 6am on TH-cam and at this stage, we only have enough footage to do that and not enough to get a few weeks ahead for patreon's
Subscribe, subscribe, subscribe. We could do with some additional help to move us on our journey. The more subscribers we get the more motivated we become.

Enjoyed the details, looking forward to seeing more especially ss!
Glad you enjoyed it Allor
Keep up the good work. Enjoying your channel. Cheers from NZ
Hey Paul good to see you back in it. Keep safe and don't push it but keep rolling!! 👍👍👊👊🛠🛠
No Pushing here lol. This shoulder now feels great and it is good that my mind is still guarding it. Steady exercise and movement is the key.
@@TheadventuresofSherylandPaul 👍👍 glad it feels great man! Keep rolling!!
hi paul i was impressed with the test results of your welds and the information was great
Thanks Nev, we are glad you enjoyed it.
Good on yer Paul keep it up
Thanks Kev. Moving along nicely now.
Thanks , another good episode
Thanks Liam. We love these comments.
Really interesting Paul, last time I did any welding was 49 years ago when I was a full time student at our equivalent of your TAFE, of course it was only stick and bronze back then. We had an excellent ex-trade tutor who could lay down the most beautiful welds but I don’t remember doing any destruction testing. I was pretty shocked with the results you got on the flux core because I could see how tempting it would be to use. I’d quite like to see that “nick” test done on a strip of unwelded metal just to see what happens. Glad to see you regaining mobility on that shoulder and I noted you being really careful moving that U channel around 😀 I’ve been following Project Brupeg for a number of years and the trials and tribulations they’ve had with welders and plasma. Even though I never got to do any metal work in my engineering career of 43 years I’ve always had an interest in the process and knowing how difficult it is to do a good job much admiration for those that can . Cheers from across the ditch.
Thanks Chris. I remember my TAFE teacher laying down the most beautiful welds also it wasn't until a few years later I achieved the same results. I was mostly a fabricator when I was on the tools. I was never really a fan of sticking my head in a helmet all day long on a 45 degree day and being alone with my thoughts. I think I have been watching @Project Brupeg for about 4 years now. I've learnt about welding machines the same way they have. I learn that because it's cheap it usually is. Funny, I did a trade then became a draughtsman then did a diploma in structural engineering then I started on my degree in my 30's, I never finished it because I learnt what engineers made and boilermaking made more sense at the time. When I get gas I will do a nick test with it and some mild steel. I am thinking of becoming a TAFE teacher at the moment. Then I can use their gas lol
@@TheadventuresofSherylandPaul Thanks for sharing that Paul. What I remember most about my NZCE (NZ Cert in Engineering) as it was called back then, was that the best tutors were the ones that came from a long time in various trades be it hands on work or more desk bound . We had one amazing guy (Charles Martindale) who was well into retirement and had been the Chief engineer at some of our biggest infrastructure and electricity projects in the 50’s and 60’s. He managed to bring the otherwise incredibly boring “Civil Tech” (mainly contract law and NZ Standards) to life with stories from his working life, many of which stick with me to this day. So certainly if you are thinking of being a tutor don’t underestimate what you can bring to the table.
Thank,s i enjoyed that. Look forward to seeing the engines ..
Thanks Mal, you and me both. I've just been informed by the boss that I have to get Hawkeye fixed up to sell her so I'll be spending time down there this coming week also. The engines may not get a look in until then.
@@TheadventuresofSherylandPaul Shame about having to sell her. Still plenty more around when the time comes. . Maybe she might let you keep the engine thats need looking at. Sould be any easy sell with bottom in the boat. Hopefully make money out of it.
Thanks for the tutorial. The price of gas is a problem especially of you only use it now and again.I am sure you will do a good job on the welds on the boat and don't worry if you are a bit rude from time to time.
Thanks Bob, It's not so much being rude it's coming across as arrogant. I don't like being like that. Sheryl and I are about giving and being nice to people. We walk away from people who are aggressive and rude, if you know what I mean.
There are many ways of doing things and the one that works is the way you do it at the time. Wait until you see how I put those rails in. I have no plan yet so it's going to be a wild one lol.
I think your decision to stick with the stick for under the water line is a smart decision I would've done the same. Plus I've welded a lot of flux core in my day but I do believe stick is a far better welding procedure I believe with mig its difficult to control your heat and the longer your welding bead is the hotter they seem to get. Yeah cannot control the heat as good as you can with stick in my opinion. that's why your weld with the mig is so brittle as far as I'm concerned. I was watching a video where a guy was laying stringers vs weave and I was surprised to see that the tests done on the weaves was producing too much heat compared to the stringers and therefore the welds were too brittle in the end. Anyways cheers nice Job Paul.
The tensile strength between the wire and the electrode was considerably different the wire is 410mpa and the electrodes are 480mpa. A MIG process would be better using solid wire than a stick any day of the week for this type of production. The L1 solid wire and the Low hydrogen electrodes share the same mpa rating. The sales rep told me you should never weave more than 3 times the diameter of the electrode you are using. So if you are using 0.9mm wire your weave should be no more than 2.7mm from side to side. Same goes for most processes. Cheers
Good your not using FC only 1 in 20 welders that we trained passed the test , and that was in ideal conditions , when we got them into their first production welds many failed , eventually we abandoned FC ,
Take care with that shoulder 🏆🏆🏆🏆
Hey John, I passed a test using NR211 a fair few years ago. I think this wire is probably only good enough for making gates and handrails lol. It would be good for the farmer, just not suitable here where a bit of structural strength is required. The weld itself tested well, there were no inclusions or lack of fusion so it was pretty good generally.
My Shoulder is doing really well and I am looking after it.
