The beginning of the story is that the guy inserted a pneumatic suspension in the GAZ-21 Volga:

One of the comments:
Leaving a native suspension is a murder, and cooking a forged barrel is okay, right?
- In the place of welding, the voltage is minimal - this is the time, Secondly, the forged bar is made of steel 40. Steel 40 refers to limited welded steels so before welding heated the whole part to a temperature of 200 degrees and then only boiled. They were boiled with an unmolten electrode in the middle of argon. Aristod imported wire for steels with a fluidity limit of up to 700mPa. The seams were cut straight to the root. Each sew was prepared in 7 receptions. with subsequent cleaning and polishing to remove surface voltage concentrators.
Okay, I have convinced you.
