Abstract

The invention discloses an equalizing beam longitudinal joint back chipping-free full penetration submerged-arc welding forming process, comprising the steps of S1, preparing a plurality of sheet materials of which the sizes meet the requirements; S2, checking the flatness of the surfaces of the sheet materials, and performing cutting-raw-material on the sheet materials by adopting flame cutting; S3, performing cutting on longitudinal joint positions of a web and a heavy plate; S4, polishing and eliminating residual oxide skin at the position of a V-shaped groove; S5, performing flame roast on the longitudinal joint and periphery of the longitudinal joint of the sheet materials; S6, performing filling and capping in sequence on the longitudinal joint of the front surface of an equalizing beam by adopting submerged-arc welding; S7, performing polishing on the longitudinal joint of the back surface of the equalizing beam; S8, performing capping on the longitudinal joint of the back surface of the equalizing beam by adopting the submerged-arc welding; S9, performing ultrasonic UT flaw detection and ray RT flaw detection on the longitudinal joints of the equalizing beam; S10, cutting out an end tab and a run-off tab on the longitudinal joints; S11, performing labeling on the examined and qualified equalizing beam. According to the forming process provided by the invention, the aim that the production efficiency is increased, the labor intensity is lowered and the welding production cost is reduced is achieved.

Description

technical field [0001] The invention relates to the field of welding, in particular to a process for forming longitudinal seams of balance beams without root cleaning and full penetration submerged arc welding. Background technique [0002] In the field of welding, submerged arc welding has been widely used in welding production due to its advantages of stable welding quality, good working conditions and easy automation of the welding process. It is mainly used in important steel structure manufacturing industries such as pressure vessels, box beam columns, ships and pipe sections. [0003] At present, the submerged arc welding process mainly includes FCAW backing, front submerged arc welding, back carbon arc gouging, and back submerged arc welding. Back carbon arc gouging not only increases the welding production cycle and the cost of welding consumables, but also produces pollution such as dust, smoke, noise and arc light, which deteriorates the working environment of wor...
