FIREBAR® Tubular Heaters Work Faster, Last Longer In Welding Pre- heat Problem: Preheat steel hull sections to obtain proper welds. Traditional round tubular elements have difficulty achieving intimate contact for good thermal transfer, resulting in premature failure. Solution: The versatile FIREBAR ® has proven far superior to other heaters in many applications including pre-weld heating. The ship building industry, as well as other industries that weld heavy metal plates together must normally heat the plates to a temperature of between 350 and 150 and 230°C (450°F) before welding. In some instances, heat is also applied immediately after welding to prevent the welds from cooling too rapidly. The pre- and post-heating improves the weld quality and prevents brittle welds.
