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.

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)

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.

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.

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.

Stick weld it - easy!

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