LUO Xian, LI Zhe. One side welding both sides forming technology and quality control of butt welding in the overhead position with shielded metal arc welding[J]. Eletric Welding Machine2019, 49(12): 114-116.DOI:
One side welding both sides forming technology of butt welding in the overhead position with shielded metal arc welding(SMAW) is summarized. The preparation before welding
selection of electrode
the operating points during the welding of backing layer
filling layer and covering layer are also introduced in detail
so as to control the appearance of weld
improve the welding quality
and provide reference for the follow-up production work and the training of backup technical personnel.
