welding triangulation?
What's the deal with welding inside the tight angles to secure the triangulation. I had a go on some practice tubing to no avail. The nozzle
gets in the way!
Any advice appreciated as always
Cheers in advance.
Matt

For TIG welding you extend the tip out further, use a gas lens, and come in from the sides. I have no idea about MIG other then coming in from the
sides also.

I have an old nozzle fishmouthed on 2 sides to get close in. It is awkward, but work from the outsides inward as most of the stresses are on the
corners (use higher amps)
If you can keep you head, whilst all others around you are losing theirs, you are not fully aware of the situation

When I do them I tend to do both sides and run the weld over, then from the front join the two sides. It makes a pocket to weld into and holds the gas
if you are a bit far away. Keep the power up.

I went into the RSPCA office the other day. It was so small you could hardly swing a cat in there.

just do what i did...
polyfiller and paint, the inspector will never notice  
seriously, for the wider angles its not too hard to get in (from the side, as kb says). for tight angles, consider adding a small piece of metal to
bridge the gap, and weld round it. if ya see what i mean. 
Beware! Bourettes is binfectious.

I cheated there and brazed the unaccessable side.

all i did was turned the feed and gas up squirted it in there! turned very neat but would recommend practicing on a few scrap bits first.

Buy a "tapered nozzle". Do it the right way, $15 or so.

Cheers guys, I'll see if i can get hold of a nozzle today so i can modify it and get in there. Otherwise i'll blue-tack it.

Cut up a spare piece of box and weld that in - kind of like a 3D fillet? Adds strength and makes for better accessability
