| Abstract: | The weldability of D6AC ultra high strength steel is analyzed, and the fundamental of tandem sequence submerged arc welding with thin wire is introduced. Welding tests are carried out to study the procedure of D6AC ultra high strength steel welding with the tandem sequence submerged arc welding technology, and the character of welding ultra high strength steels by use of this method is analyzed. With the thin wire tandem sequence submerged arc welding technology, the cracking problem existing in the welding of D6AC ultra high strength steel can be solved, the welding automation can be realized at low cost, and the low efficiency of TIG pulse welding and the high cost of high energy density welding are avoided. |
