Friends, I greet all of our regular readers, and channel visitors, is dedicated to all those who have decided on their own to master the manual arc welding, simply put, is dedicated to all self-taught.
Today, an important theme-tell Make a dock and welding of two profile tubes. The main secret to happen smoothly.
I show the example of mating and welding of two pairs of profiled pipes. One pair is proftruba 60 to 30 mm, 2 mm thick, and the second pair 60 by 40 mm, 3 mm thick.
For this operation, it is sufficient to have one flat surface. We docked on the surface of the welding tragus.
Spread the half pipe on a surface, the joints combine smoothly.
The horizontal surface in our flat, the issues will not be.
Now we need to align the vertical plane of the pipe. Just look along the edges combined pipes, looking along the edges can catch the smallest curvature, so the look and align.
4 Put the pot holders, oven gloves but do strictly on the diagonal joint.
Produce visual inspection, also along the edges proftruby We look-eye notices the slightest deviation from a straight line.
If there is a slight curvature after tack, just a little podrihtuem hammer butt up perfectly smooth state.
And now we come to the point of welding seam. The main problem here is that you can not at once fully cook the first seam. A welded need only 50-60 per cent of the length of the seam.
We turn over a tube and the opposite seal extends entirely.
Overturn tube back and cook a little longer first seam completely. The same sequence of welding we do on the other two sides.
Why do I do that? Just at the time I had a lot proftruby docked, and through trial, error and experimentation it came to such a method. But if the first seam to do once the full length, after cooling, the tube is slightly zavernot this first seam. The first suture has a greatest utjazhki proftruby interface.
Welded joints of profile pipes. Now we need to wait until the welds have cooled, or when they are hot, the pipe (docked) will be a little uneven.
Pipe joints have cooled down, make a visual inspection. Everything happened exactly. Now zashlifuem zero welds at the joints and check again ruler.
Everything is good, everything is smooth.
Now let's see the video with this process-docking and welding, the video turned out very informative and helpful.
