Description
Technical field
The present invention relates to welding methods, are exactly a kind of electrolytic cell bottom plate square groove splicing welding methods.
Background technique
Usually there are three types of sizes for domestic aluminium cell bottom plate: refined aluminium 3m*8m, medium-sized 4m*12m, large size 4m*18m.Because of plate
The comprehensive consideration of material transport and project cost, trough floor cannot all determine roll the plate for meeting drawing size, and therefore, trough floor will be
Length direction splicing.Usually during the long weld seam splicing of big plate, curved ruler line gauge side first is drawn in plate end, cutting line is drawn, cuts
Groove is shoveled again after the completion of cutting, and then splicing is fixed, and after gas shielded arc welding bottoming, automatic welding welding, after reverse side cleaning, automatic welding is again
Welding.Whole process is got off, and heat input is more, and cutting, welding deformation are larger, and it is difficult to correct after deformation, simultaneously as plate splicing
Weld seam is too long, will cause the deformation of all directions, most serious is exactly to heave, and the contact surface between trough floor and bassinet stand does not add
Rib, reparation difficulty is larger, makes a big impact to subsequent masonry, uncontrollable using flame heating correction result.It causes
Waste of time, material and artificial waste, producing efficiency is relatively low, can not form the processing of standardization, mass.
Summary of the invention
The technical problem to be solved in the present invention is to provide a kind of electrolytic cell bottom plate square groove splicing welding method, this method

It stays spot welding after 3--5mm weld gap to fix, solder flux is filled up into weld gap；
(4) it is welded using welding machine along weld gap, until welding is completed；
(5) horizontal platform is hung after overturning bottom plate, detects the bead formed on back situation at weld gap, if molding is good, directly
Cover welding；Locally-shaped bad fault location is handled, repair welding, makes the weld is accepted at the back side, then carry out cosmetic welding
It connects.
The present invention by adopting the above technical scheme, compared with prior art, the feature protruded is:
When electrolytic cell bottom plate splices, a splicing mould is first made according to backplane interface position, the channel steel of filling flux is set,
By the processing at interface position and the double protection of bead formed on back solder flux, when welding, single-side welding double-side forming is simplified
Splicing program reduces welding sequence, high in machining efficiency, while also solving the problem on deformation of welding, make splicing it is simpler,
It is efficient to form continuous productive process, reach mass production, reduced the cost of production greatly, saves artificial and material wave
Take, improves the producing efficiency of entire electrolytic cell.This method is suitable for small-sized refined aluminum electrolysis slot, medium-and-large-sized aluminium ingot electrolytic bath bottom
Plate splicing welding, welding steel thickness is up to 12--16mm.
Further optimal technical scheme is as follows:
The electrolytic cell bottom plate to be welded welds pre-treatment, first plate is carried out to steel plate with purl machine, by rolling in steel plate
Internal stress processed is released before splicing, then again by the polishing of steel plate docking weld bond, processing.
It is pre-processed through the above steps, further controls the deformation in welding process.
The splicing internal model making, using the channel steel of notch upward as weld groove, weld groove is interior to fill full graininess solder flux；
The channel steel of notch upward is linked together with notch mould levelling channel steel directed downwardly by the fixed square plate of mould, to guarantee splicing tire
Has rigidity, flatness.
Splicing mould is made through the above way, splicing mould is made to have preferable undertaking ability, further control welding
Problem on deformation in the process.
