Why can not the finish thread steel be welded?
Finish rolling thread steel can be directly connected with sleeve, and do not use wire; you want to weld can also, it is estimated that the user does not require welding, welding prone to appear strong phenomenon. If welding is used, buy the finish steel, which is more expensive than the other threads of the performance.
This is generally superior to alloy steel. Carbon content is relatively high, poor weldability, welding conditions are very demanding, but also produce high temperature welding, it is easy to destroy the original material performance. So, under normal circumstances, on-site welding is not allowed.
