Re: Let's practice STICK WELDING, and proper weld bead applications.

To continue with the other tubing/pipe that I re positioned, I started applying spot welds one at a time until whole joint have been covered.

On the last two pics shown,aside from applying welds on the pipe joint, I got curious that I applied also some welds on the grinded corner joints to see if it can withstand additional heat from the welding rod without punching a whole.

Re: Let's practice STICK WELDING, and proper weld bead applications.

After applications of welds, chipped off the slags to reveal the final welds.

Re: Let's practice STICK WELDING, and proper weld bead applications.

After chipping off the slag from the welded joint, I applied additional welds on the corner joint using small weaving pattern .

Re: Let's practice STICK WELDING, and proper weld bead applications.

Any way, going back to the 1" GI pipe welded joint, i started grinding the welds around the tubing/pipe to even out its appearance.

Re: Let's practice STICK WELDING, and proper weld bead applications.

And the final appearance !!!

Re: Let's practice STICK WELDING, and proper weld bead applications.

AND NOW FOR THE SMALL TUBINGS LIKE 1/2" GI PIPES :

This is just a SIMPLE EXERCISE for me to find out if in case I use some smaller size pipes/tubings, to find out on how I will approach again on what to choose to connect same size of smaller pipes.

Same thing again, shaped the tips of the pipes to be welded.

Then as the pipes have been positioned, I again started to apply tuck welds or spot welds on the joints.

Re: Let's practice STICK WELDING, and proper weld bead applications.

Simply tack welds, nothing more, nothing less !!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!

Re: Let's practice STICK WELDING, and proper weld bead applications.

Now, why did I shared these exercises on these pipes/tubings ? My main purpose is to show our new welders that when doing some projects like possibly small metal gates, window casements or grills or maybe some stands for your planters or shoe racks etc etc, you will usually use small sizes of angle bars, flat bars or maybe some BI or GI pipes and tubing.

Usually the kind of weld application applied on this metal projects during the process of assembly will be tacking or spot welding, very seldom that you will be using weld weaving or manipulations.

That is why I urge you welding newbies to do lots of weld bead exercises, the ones I have shown in the early postings of this thread. Getting used to applying weld beads, in my honest opinion will be one of the foundation in applying several continuous weld bead applications in future large metal projects. So just continue practicing how to deposit decent weld beads as often as you can and by doing so you develop your wrist and arm control in applying welds., ika nga eh PULSO ng KAMAY dapat masanay !!!!!!!!!!!!

:poke: :p 😀 😉
So BROS, PRACTICE, PRACTICE, PRACTICE AND PRACTICE pa rin !!!!!!!!!!!!!!!!!!!

Re: Let's practice STICK WELDING, and proper weld bead applications.

Bro ... are the pipes not thick enough to do continuous welding. I'm curious as to why you used the spot welding technique to full weld the joints.

Maybe the pipes are not that thick because you also did not bevel. Papasok kasi ng konti mga welds pag me bevel so less grinding.

So far I haven't tried welding pipes yet. If I finish my current WIP I'll do a couple of practice too. I remember I have some scrap pipes laying around somewhere here.

Your post are very informative.

Thanks bro.

Re: Let's practice STICK WELDING, and proper weld bead applications.

@ JayL,

YES BROTHER, pipes were not that thick so no beveling was needed for the pipe joints, the thickness of the pipes were only a bit more than 1/16" of an inch, so that'll be 2mm+ or an equivalent of gage 14 or 13 thickness if we are talking of plate/sheet thickness. If the thickness were at least 1/4" or 3/8", yes I could have beveled the edges. 😉 But you see these are just ordinary GI pipes that you can buy in hardware stores that sells only 2 gauges, gauges 26 and 30 for pipes which are really not that thick.

For these exercise, I used 3/32 welding rods and set my amperage to 80 amp on the first pass then on the second pass since the metal has thickened already, adjusted it to 90amps. If you will notice on the later part of the 1" GI pipe exercise, I played around with the corner joint and applied very carefully continuous welds with very minimal weaving since the joint has thicken already due to previous weld application , and it did work quite well. :clap: 😀

Well anyway bro thanks and hope this will be helpful for our new welding newbies practicing their welds. :rolleyes:

Re: Let's practice STICK WELDING, and proper weld bead applications.

I think this is worth sharing specially for our new welders here on the forum and specially for all the new owners of the YAMATO 200amp DC Inverter arc weld machines.

This I noticed from the time I started using or practicing with this machine. OK, a while back, I was welding two pieces of thick angle bars together, about 5/16 or 5/8 of an inch which I mistakenly have cut a few months back. Beveled one angle bar, positioned together, applied tacks on strategic parts and then started to apply a root pass using a 6011 twice on the outside portion and then capped it with 6013 rod. 😉

Since I was already in the process of welding a thick metal, I decided to try all my available welding electrodes, from the 3/32 to 1/8 E6013s, the 6011, the AC and DC 7018s and the 7024. What I have noticed in using all of this welding electrode is that every time I stop applying welds then re start again, I will have to scratch the tip of my rods on a course sand paper or scratch panel to expose the metal inside to be able to again start applying welds. :confused:

This I have not experienced when using my Yamato AC weld machine. Now is it how it is when using a DC weld machine ? The metal core would be consumed inside but living some flux coating of about 1/8 to 3/16 of an inch outside almost covering the metal inside and making it a bit difficult to re start an arc. 😮 I supposed most of you guys using this Yamato DC weld machine have experienced this odd behavior of your welding electrode while practicing. Guys, have you experienced this too ?

HHMMMMMM, I think this will need more research in the internet. :rolleyes:

Re: Let's practice STICK WELDING, and proper weld bead applications.

Bro Rosy ... I have not noticed this except for 7024 rods which is normal. I will check it out too when I use the welder again.

Re: Let's practice STICK WELDING, and proper weld bead applications.

I also experienced this last weekend with stainless welding rods.

How was the Yamato with stainless steel rods?

With regards to the flux issue I'm sure Bro Rosy will investigate this further.

Akala ko may mali sa ginagawa ko. Kaya minsan niraratrat ang pag weld hanggang maubos ang isang rod. Pag tumigil kasi minsan hirap mag start uli ng arc.
Ang siste naging trigger happy, pagkatapos ng isang rod, reload agad. Ayun tuloy nag OC error hehehehe
