Title: Narrow gap submerged arc welding method
Inventor: SUGIOKA ISAO
IPC: B23K9/18
Filed: 1984-03-06
Abstract: PURPOSE:To perform satisfactory butt welding without back chipping in double Vee groove multi-layer butt submerged arc welding by setting the groove angle on the finish pass side at a specific large angle with respect to the specific groove angle on the backing pass side, and setting the root gap width to a specific width. CONSTITUTION:Double Vee groove multi-layer butt submerged arc welding of thick plates is small in welding sectional area and is highly efficient. The groove angle thetaB on the backing pass side is set at narrow 25-45 deg. and the root gap G at 1-5mm. width. The finish pass groove angle thetaF on the opposite side is set at 30-55 deg. wider than thetaB. Welding of backing pass has a tendency to shallow penetration but the depth of penetration is adequate with the root gap G of such degree. The welding of the root part is thus satisfactory executed in the finish pass of the wide groove angle without requiring laborious back chipping. Welding with the higher economy is accordingly made possible.
