HI Sagar,
You can create a workflow rule on Order object with Rule CriteriaOrder: Order TypeEQUALSNew and Evaluation Criteria as "Evaluate the rule when a record is created, and any time it's edited to subsequently meet criteria"  with Workflow Actions to update field i.e., Master_Order_ Number__c.

While creating field update, choose "Use a formula to set the new value" and give Order Name.
 
Hope this helps you. Please mark this answer as best so that others facing the same issue will find this information useful. Thank you
