Abstract

The invention provides a process for welding a bent box type. The process for welding the bent box type comprises the following steps: S1, groove preparation: forming grooves in a box body wall plate and a part plate; S2, part plate assembling: placing a flange plate on an assembling jig frame, then assembling webs on two sides of the flange plate, finally, assembling an inner partition plate in the middle of the flange plate, to complete the part plate assembling action; S3, assembling an electroslag welding holding strip; S4, performing welding for the first time; S5, performing welding for the second time; S6, assembling a cover plate; S7, forming electroslag welding holes; S8, performing welding for the third time; and S9, performing ultrasonic acceptance inspection for a weld joint. According to the process, stable assembly of the bending box type is achieved through assembly of all the structures, then all the structures are stably welded together through electroslag welding operation, and accurate and stable connection between a partition plate and the flange plate when the angle between the partition plate and the flange plate is not 90 degrees is achieved.

Description

technical field [0001] The invention relates to the technical field of electroslag welding, in particular to a process for welding a twist box type. Background technique [0002] Electroslag welding uses the resistance heat generated by the current passing through the slag as a heat source to melt the filler metal and the base metal, and form a firm connection between metal atoms after solidification. [0003] At the beginning of welding, short-circuit the welding wire and the welding slot to start the arc, add a small amount of solid flux continuously, use the heat of the arc to melt it, and form liquid slag. When the slag reaches a certain depth, increase the feeding speed of the welding wire, and Reduce the voltage to insert the welding wire into the slag pool, and the arc is extinguished, thus turning into the electroslag welding process. [0004] However, in the welding process of steel structures in the prior art, electroslag welding can only realize the welding of co...
