Door hinge come off from metal frame

[asimraza]

Hello,

What is the fix for this problem? The hinge has came out from the metal frame and it looks that frame hole has been cracked a bit. I'm a new home owner and bit lost who to contact for the repair. It looks like the frame needs some welding work.
