Magento 2.2.2 - Remove default welcome message and show username post login

Question

I need to remove default welcome message from header but display username after successful login. Tried below to hide welcome message but it also removes username after login

<referenceBlock name="header">
    <arguments>
        <argument name="show_part" xsi:type="string">other</argument>
    </arguments>
</referenceBlock>

Also tried below

<referenceBlock name="top.links">
   <referenceBlock name="header" remove="true"/>  
</referenceBlock>

How do I achieve above using xml and without overriding template file ?
