Re: Chopsaw Stand

Cleanest weld pero may butas parin.

Tips are highly appreciated

Looks good from here ....

Re: Chopsaw Stand

Bro ano thickness ng square tube mo?

Re: Chopsaw Stand

@ crazyboi_6,

Was that your first joint of your tubing project ? Did you tack weld some four corners of the tubing ? For your next tubing joint try applying this technique, try applying tack welds or weld beads one after the other, not overlapping beads but just one after the other until you cover all the joints, purpose of this is to prevent you from melting the tubing surface to much and creating a hole plus this thickens the wall of the tubing particularly the edges that easily melts due to excessive heat. Let it cool down then chip off the slags to expose the deposited weld bead. Between those beads are still perhaps some gaps, do the same procedure as the first one, applying weld beads in between your first two beads to cover the gap and so on and so forth until you cover all the gaps in between, chip off the slags again then you can grind the weld beads deposited to produce a fine finish up to the surface of the tubing.

This is just a simple and easy technique for first timers who still needs to practice wrist and hand control during welding. There are other simple techniques but better to start with this one first, anyway you will be grinding them beads pa. For thin gauge wall, use the 3/32" rods at 70, 75, 80, 85 to 90 Amps only. Try to experiment on those settings on a scrap material and see what will suit you best, to much heat melts thin metals fast so stay with the lower ampere settings.

Do post more of your progress with the other tubing joints so we can discuss and perhaps suggest other approach. Don't expect to much agad, just be patient and learn from previous mistakes, plus do practice more on scrap tubing so you will get to feel the right approach and not ruin your project.

CHEERS and GOOD LUCK !!! 😉 🙂 😎

Re: Chopsaw Stand

@bugel
i'm using 1.5 tubing

@rosy
i'll try that technique, hirap pa talaga ako mag start ng arc. pano ko pala matatapalan yung butas? tried welding it pero lumalaki lang. hehe

Re: Chopsaw Stand

Lagyan mo kaya muna ng filler .... flux stripped welding rod or wire ( malaki na kasi butas ) ... bago ka mag tack welds to fill. Later pwede mo naman grind down para mag flush. Kaya lang konting technique din para wag masyado maraming grinding ..

Re: Chopsaw Stand

@ crazyboi_6,

Bro, what bro JayL suggested is one technique, here is another one, apply a weld on the edge of the surface for a few seconds then retract the rod, so habang medyo mapula pa yung deposited weld, apply another weld then wait for it to cool a bit and again, habang mapula pa yung weld apply another one doing the same, retract the rod, wait again a bit for the weld to cool down a bit then re apply again then so on and so forth til you finally patch up the hole. Let it cool completely then chip off the slag. If you have successfully covered the hole, wire brush the surface and then apply again several beads all over the area where you punched a hole, purpose of this is to thicken the wall surface.

Chip off the slags again and then you can start grinding and flatten the surface. Practice this again on a scrap tubing and see how and if you are improving !!! :boxing1: 😉 Oh stick to the low ampere setting to minimize burning the edges too much !! 😎

Re: Chopsaw Stand

Bro hope you allow me on posting these pics, this is what I mean by practicing first on a scrap material, before attacking the main metal project. Purpose of this is to familiarize yourself with the thickness of the material, study the right or use the proper ampere setting and use of right welding electrode

I did this recently since I have an urgent metal project needed for a current or existing one. I have to do a practice application on Z-Bar with 1.5 mm thickness and my project would require using that thickness, actually its a 2.0 mm T-Bars that I have to butt weld.

Anyway here are the pics bro. 😉

The Z-Bar that I welded together using different ampere settings.

I measured the thickness of the material and its 1.5 mm thick.

Re: Chopsaw Stand

And here are the practice material. Its been a while since I welded some thin sheet metal so might as well do a practice weld before proceeding with the actual one.

This is is one side/angle.

And another angle. Now I started using 100 amps, then down to 90, 80, 75 and 70 amps using a 3/32" welding rod. I think the 70 to 80 amps work better for the thin wall. Here I was just depositing weld beads, or tack welding, trying to familiarize with different ampere settings for this thin wall material.

I got a scrap 2 X 2 square tubing usually purchased at hardware stores and measured its wall and this is the measurement I got. Now may I ask are you sure your tubing for your project is a 1.5 mm thickness or its only 1.0 mm wall ??

Well anyway bro just sharing this approach, it might be helpful or useful for you in the future metal projects using this kind of material thickness.

CHEERS and have fun welding, stay safe too !!! :lalala:

Re: Chopsaw Stand

hey bro crazyboi_6, how's the progress of your metal project ???

Re: Chopsaw Stand

tack welded na lahat

had to fight warping, used my woodworking clamps.

Re: Chopsaw Stand

still have to clean the joints and full weld everything. ito na siya.

Re: Chopsaw Stand

I usually lean square tube 1/8 of an inch off to 90 degree to anticipate warping..
Even if you use corner clamps warping will occur.

Kaya first tack pa lang dayaain mu na:D

hehe. buti nga may malaki akong clamp at may spreader din.
