Requirements for groove welding of grade 22mm round steel and manual arc welding

Answer:

On the lathe, the car C9 chamfer (the car is sharp and difficult to weld, the car's chamfer is too small, the root is not welded).When welding, pull apart the gap of 2mm above the root clearance, the condition allows the edge to rotate while welding, otherwise it can only be welded in all positions.
If not on the lathe, in the groove on the round bar with gouging or cutting gun, docking form X type double sided bilateral docking, blunt edge 2mm root gap 2mm welding, welding side sincere one or two seam, flip the workpiece on the other side of a full weld groove, flip weld residual,
Chamfer or breach can also be used in grinding machine, notice groove surface cleaning with carbon or gas cutting, consider the parent material selection process, such as carbon will carburizing etc.
