Prospects for the production of welded and seamless tubes at reduced temperatures

A technology has been developed and tested for making welded reduced tubes. The technology includes heating of the semifinished product to temperatures in the α [arrow right] γ transformation range before the forming operation, HFC preheating of the edges of the semifinished product, welding, and re...
