Abstract
The invention discloses a welding process of outside wind tower U-shaped grooves. The process includes the steps of preparing grooves to be welded and making double-V grooves by thermal cutting; welding the single side of each groove before machining the reverse sides of the U-shaped grooves; and welding the reverse sides. The welding process of outside wind tower U-shaped grooves is high in machining efficiency, low in noise, dust-free, and accurate in groove machining size; the grooves are machined into standard U shapes; welding quality is high; and welding materials are saved.
Description
Technical field
The present invention relates to the U-shaped groove welding procedure in a kind of wind tower outside.
Background technology
At present, the longitudinal joint on the wind tower and circumferential weld mostly adopt double V-shaped groove design, and when finishing one-sided groove welding, reverse side adopts the method back chipping of carbon arc air gouging, and by abrasive machine reconditioning groove, finishes the welding of reverse side then.The operating efficiency of this method is very low, and noise and dust are bigger, and the reverse side groove that carbon digs and polishing is come out, and size can not be very accurate, and may will increasing of weld defect appears in follow-up welding.
Summary of the invention
Goal of the invention: the objective of the invention is in order to solve the deficiencies in the prior art, the U-shaped groove welding procedure in a kind of wind tower outside that provides, it is low to be intended to solve reverse side groove back chipping and grinding efficiency, and the noise dust is big, the coarse problem of groove processing dimension.
Technical scheme: in order to realize above purpose, the U-shaped groove welding procedure in a kind of wind tower outside of the present invention, concrete steps are as follows:
(a) with the mode of thermal cutting the obverse and reverse of steel plate is opened " V " type groove respectively;
When (b) steel plate being heated to 65 ℃-110 ℃, " V " type groove in steel plate front is welded;
(c) after the welding of " V " type groove in steel plate front was finished, when treating that steel billet temperature drops to 10 ℃-50 ℃, " V " type groove with the steel plate reverse side adopted mach mode to process " U " type groove again;
(d) after " U " type groove machines, steel plate is heated to 65 ℃-110 ℃, again " U " type groove is welded;
(f) the reverse side welding is finished.
Machining mode described in the step (c) is for to carry out method for processing by artificial employing beveling machine or milling machine to steel plate.
Beneficial effect: the U-shaped groove welding procedure in a kind of wind tower outside provided by the invention has the following advantages:
1, working (machining) efficiency height;
2, noise is very low, free from dust;
3, the groove dimensioned is accurate;
4, to be processed into standard U-shaped for groove, the welding quality height, and, saved welding material.
