I literally just spent most of my day searching and searching as to why my squares were not “squaring” up at the end. Didn’t find jack anywhere until 11 o’clock at night. Much appreciated man gonna tackle the project and hopefully get it right tomorrow!
Another outstanding video. I watch several welding sites and you are the best. I hope you really understand exactly how helpful you are to us rookie welders. As always, thanks for taking the time to share your knowledge.
Very well done. We do a lot of large and heavy stainless weldments. That stuff is much worse for weld pull than say A36 or other mild steel. In some cases they give us what they call weld maps showing the process or sequences to use to reduce the pull as much as possible. Very good video and you are spot on with your thinking and explaining.
Cheers, yeh anytime I've done stainless manifolds its always a nightmare trying to keep the flanges flat. Ive never heard of weld maps before, that sounds really interesting. Is that just a welding sequence added into the drawings etc? im guessing there's probably cad programs that can predict that stuff before its assembled these days?
Yep, I still get caught out occasionally, I tend to go for the fast tacking up thing as you described, sometimes I'll tack one side up and then weld the opposite side and this pulls it square but I started doing that for some jobs after I got my bandsaw which cuts 90° and 45° dead on so the material butts up square.But I still keep checking for square as I go, that way, if its pulled, I usually only have one weld to cut out.
You helped so much with this video!! I wish I had seen it two days ago though!! hehehe I created a beam using two square tubes and had a problem with bending!! Well lesson learned!! thanks a lot!!
Thanks for this video Matt, like in all of your videos, you always give good sound practical advice. I'm particularly interested in distortion control, as I have been asked to weld / make up a big pair of gates and obviously want to do a good job. - I know there could be much more work to come my way if I do.
Good information, thank you. Are there any tricks for welding a panel on a car (not clamped to table). Any suggestions on how to keep panels from warping? I"m just learning how to weld and found my first practice piece warped all to heck. Thanks
Super smart man. Thank you for the tips, as this has been a major pain in my asshole while trying to weld up an up pipe for my turbo. .060 stainless 3” tubing, tons of pie cuts, super hard to find a way to clamp the pieces. It’s been a nightmare for a newb like me...
Can a spring be bent using a welder and thus be reshaped? What way will it bend? I am guessing it will bend toward the bead side. But will it still act as a spring?
Yes about the weld maps, you are correct for us this is a drawing where the individual welds are numbered for the welding sequence. Not totally sure about any software for making these calculations. I believe they mostly are from mistakes and experience. The engineers collect the information and put the instructions on the drawings because the parts could be welded by different persons or a new person. Usually if you follow the drawings even for the first time you weld up one it always works out good. These are usually for recurring jobs like two or three a year but not high volume. Have a good day!

Thanks, that's much appreciated.
Great tips Matt. Thanks again.
Another first-rate explanation and presentation. Again, I learn from you. Well done and thank-you
Really useful tips. I never really thought about this happening. Thanks!!

Well presented, great technical help. Appreciate it! Keep posting homes!
Cheers, Will do

Thanks mate. learnt a few new things from that one.
Cheers.
Great video Matt, thanks for sharing. Cheers
Thank you sir. This was very helpful.
Superb! Thank you for sharing!
very well explained thanks

Thanks - great video!
Great advice again keep um coming mate 👍

Yeh its tricky bud, stainless warps like a bastard.
Urchfab I think it hates me.
Thank you brother
Close enough mate is good enough.
I hate the idea of leaving a gap, because it feels out of my control but I guess I should practice it more

What way will it bend?
I am guessing it will bend toward the bead side.
But will it still act as a spring?
To bend the S of the NOS Homelite 350, 360 Chainsaw "S" Clutch 68362-4.
Because it is worn out
Don't you do the fillet weld last cause it has most pull?
Usually I just angle it a bit more so when it contracts it shrinks into the proper shape :/
Thank you!
Cheers
Excellent explanation- thank you

In theory if you clamp it so tight that it dont move the weld would be damaged or crack as it shrinks
Cool !!
if youll tack it good,b4 you weld it up, it wont distort the metal
Unfortunately thats not true.
Was that a MK2 in the background?
Sure is.
Miss mine, used to live in Bideford, so I can understand you quite well haha. Good video.
When are you going to make a metal folder so I can steal your plans?
Its on the list mate.
Thanks for the video, but there is no molecules in metals. They're atoms arranged in crystal grids.
Thanks for the Video
Too much talk no welding
