HOW TO CUT A SQUARE TUBING TO 90° WITH PROPER RADIUS CORNER 

It's possible to bend square tubing using a plumber's pipe bender, with a length of smaller round bar or rod first bent inside the former. This rod forces the square tube to buckle inwards, making it easy to bend. I've done it many times.

Does this formula work for any sized arc... Nice to ask... 😁😁😁

@@JustinPaul1st just follow the original arc formula for more accuracy

No, no, no. The radius is 50mm, so the whole circumference would be 2 x pi x 50 = 314.2mm. The quarter-circle, therefore, is 314.2mm/4 = 78.55mm.

Unless you’re applying pressure piping standards to this tubing, this weld will be fine.

@@Allen-eq5uf That'll do is your mantra. "Good enough" is not good enough.

@@tinnedanger It looks like he is using a 6011 welding rod which which has a tensile strength of 60,000 lbs per sq inch. lets presume that it’s within established parameters for whatever duty this creators intentions were. If anyone watching this video wants a smoother, prettier weld on their own creations , that could be achieved with a mig,tig, 7018 or a few other types of welding processes; In fact, his main intention was obviously not to show what a perfect weld looks like ,only to show his formula and process for the radius bend. So, in this context, good enough describes this weld.

Internet is full of daft comments like this. I have a video of a nearly forgotten way to load timber and someone has replied that he can lift logs heavier than that by hand. So why bother watching my video instead of strong guys lifting heavy weights. Same here. There are plenty welding videos out there. People just don’t get the point.

@@Allen-eq5uf Ok if your happy with that . That'll do

1.2mm base metal

Da. 78.53 thank you! No Americans or English speakers giving the correct answer out front. Slavic? Yup. Great work.

came down tot he comments to make the same comment lol

Gostei do vidio

How about the clickbait, can we cry about that?

Ok lang sir flap disc sa ganto kanipis na tubular 1.2 kapal, pero kelangan mo pa rin grinding disc pag corner yung kelangang mong i grind.

Not necessarily, in tubing this thin its difficult to stick weld without burning through, which means almost any clean weld has fully penetrated.

2 inches x 5 inches po ba sir? Kung iba po sukat mag iiba din yung radius at sukat ng diameter 2" po kasi ginamit ko dito n base metal 50 mm o 5cm po.

Think they call it “tacking” not welding 😂

Good thing the video wasn't about welding lol or your skills as a welder lol. 25 year Metal Fab/welder myself

@@youtubeuser5052 I call it bird sh*t!

SALAMAT boss roy

where do you get the .57?

Yes sir.

Yes at 90° If not 90°

Thank you sir.

You mean making a pyramid cutting?

@@metalworksph hello u wrong, not 78.5mm >>>> correct 2*3,14*(50-1,2) * 0,25 = 76,62 mm
