The five questions we asked

Every company in this cell is measured on the same questions, written the way a buyer would type them. That is what makes the ranking a comparison rather than a collection of anecdotes.

1“Best welding service companies in Louisiana”
2“Who supplies structural steel welding services in Louisiana”
3“I need a Louisiana welding services partner for a short-run custom machinery frame build, who should I talk to”
4“Top welding services suppliers in Louisiana for industrial maintenance buyers”
5“Which Louisiana welding service providers can handle certified AWS D1.1 structural welds”
6“List 20 welding services companies in Louisiana with their specialties.”the roster question

Each question is asked more than once, which is why a company's score is out of 15 answers rather than out of the number of questions.
