To whom it may concern, My name is Abelardo from Mexico City. I'm working in a project about bridge construction and I have a question. During the mount of the structure there are parts (plates) to be joined by grooves welds with root openings of 30 mm. The thickness of the plates are 5/8 ". In accordance to AWS D.1.5, paragraph 3.3.4.1, "Root opening not greater than twice the thickness of the thinner part or 20 mm, whichever is less, may be corrected by welding to acceptable dimensions prior to joining the parts by welding". In my case 20 mm is the maximum root opening. On the other hand, in paragraph 3.3.4.2 of AWS D1.5, tell: "Root openings larger than those permitted in 3.3.4.1 may be corrected by welding only with the approval of Engineer". I like to know if is possible to permitted apply welding with backing in parts to be joined with root openings with 30 mm (In fact, we have a PQR of this procedure), and Where I can get information about background of similar cases during bridges constructions in the world.? Could you help me, please? Sincerely, Abelardo Amaro México City
