Bending tube and bar.

I am guessing you tried to post a picture of something, but it didn't seem to work. What are you asking about? 

Good Morning,

Some tubing you fill with sand and weld a cap on each end, so it will bend without the tubing wall collapsing.

Neil

That IS NOT a complete weld on two ends. You must leave room for moisture vapor (when heating) or any pressure to escape.

Sand does work to support the tubing walls as it is being bent. Also helps to fill, then tamp or pack the sand down then top it off again.

Greetings Alch,

         What size tubing? What wall thickness? What type of bend ?  Drawings help 

 

Forge on and make beautiful things

There are lots of ways to bend ROUND tubing that don't involve sad, heat or special dies but I'll only confuse you if I drop tips on you and it turns out it won't make the kind of bends you need. At least post the link.

and then there are low melting temp alloys to fill tubing with and then melt and pour out---used for musical instruments by some folks...
