You can fetch customer group using below code.

public function __construct(
    \Magento\Customer\Api\GroupRepositoryInterface $groupRepository        
) {
    $this->groupRepository = $groupRepository;

public function getCustomerGroup()
   $customerGroup = $this->groupRepository->getById($order->getCustomerGroupId());
   echo $customerGroup->getCode(); // 

I hope it'll work, let me know if you need further assistance. Happy Coding :)

I had joined two tables order table and order item table
