Abstract
The invention discloses a welding method for plates and strips, and relates to improvement on a method for welding a plurality of a small plate strip rolls in rolling production of plates and strips. The welding method is characterized by comprising the following steps: during melting and welding of the plates and the strips, manufacturing two small pieces of materials, which are the same in thickness and are made of the same material, respectively taking the two small pieces of materials as a run-on plate and a run-off plate; grinding the run-on plate, the run-off plate and fracture faces on end parts of plate strips to be flush; putting the run-on plate and the run-off plate at the outer side of a welding part for the plates and strips; during welding, arching on the run-on plate and then carrying out welding on the plates and strips and carrying out arc stopping on the run-off plate after welding the plates and strips, and forming end openings, generated in a welding process, in the run-on plate and the run-off plate; and after the welding is completed, removing the run-on plate and the run-off plate, thereby eliminating opening defects of arc-striking and arc-suppressing end parts during welding of the plates and the strips. The invention provides a method for reducing and preventing opening formation in the end parts of the plates and strips; and the method is simple, high in practicability, convenient in operation, and capable of effectively reducing and preventing opening defects of welding end parts of the strips, and increasing plates and strips yield.
Description
Technical field
A welding method for Strip, relates in plate sheet and strip production, by the improvement of the method that multiple platelet roll coil of strip welds together.
Background technology
In plate sheet and strip is produced, in order to enhance productivity and roll up heavily, need multiple platelet roll coil of strip to weld together, carry out Continuous maching production.But Strip welding is in order to ensure that weld seam is become a useful person, and generally adopts molten solder, ubiquity end gap defect in Strip welding process.End gap size and the degree of depth directly decide trimming amount when processing is become a useful person, and have influence on the lumber recovery of final products.How to reduce with prevention plates band welding end gap defect most important in Strip welding production.
Summary of the invention
Object of the present invention is exactly the deficiency existed for above-mentioned prior art, and supplying method is simple, practical, convenient operation, can effectively reduce and prevent band to weld the gap defect of end, improve the welding method of the Strip of plate & strip production lumber recovery.
The object of the invention is to be achieved through the following technical solutions.
A kind of welding method of Strip, it is characterized in that when Strip molten solder, make two pieces of stack piles make run-on tab respectively with the cobbing of material and receive arc plate, by run-on tab, receive arc plate and strip end section polishing concordant, by run-on tab with receive the outside that arc plate is positioned over Strip weld, the starting the arc on run-on tab during welding, carry out Strip welding again, on receipts arc plate, receive arc, the end gap that welding process is produced after Strip welding, occur in run-on tab and receive on arc plate; After having welded, run-on tab and receipts arc plate are removed, arc gap defect is received in the starting the arc eliminating end during band welding.
The welding method of a kind of Strip of the present invention, when it is characterized in that placing run-on tab and receiving arc plate, run-on tab and receipts arc plate weld with strip expects that opposite joint is tight, its gap filler wire.
The welding method of a kind of Strip of the present invention, method is simple, practical, convenient operation, can effectively reduce and prevent band to weld the gap defect of end, improve plate & strip production lumber recovery.
Accompanying drawing explanation
Fig. 1 is the principle schematic of the inventive method.
Detailed description of the invention
A kind of welding method of Strip, during Strip 1 molten solder, adopt stack pile with the cobbing two pieces of material with being run-on tab 2 and receipts arc plate 3, the section of prior polishing run-on tab, receipts arc plate, strip end is concordant, place two sections that run-on tab welds in Strip with receipts arc plate, the in advance starting the arc on run-on tab during welding, receipts arc delayed by receipts arc plate, in welding, can effectively reduce and prevent band to weld like this be the starting the arc of end to receive arc gap defect.
The welding method of a kind of Strip of the present invention, install two disconnected portions that run-on tab welds in Strip with receipts arc plate additional, the starting the arc in advance on run-on tab during welding, receipts arc delayed by receipts arc plate, when Strip is welded end the starting the arc and receive arc gap defect extension, improve becoming a useful person of end of welding bead.
The welding method of a kind of Strip of the present invention, when placing run-on tab and receive arc plate, need weld with strip and expect that opposite joint is tight, can shear welding wire 4 fill to make up, with stable welding condition when excesssive gap.
The welding method of a kind of Strip of the present invention, install run-on tab additional and receive arc plate, the in advance starting the arc on run-on tab during welding, receipts arc delayed by receipts arc plate, the starting the arc of end and receipts arc gap defect extension when Strip weld, run-on tab and receipts arc plate are not limited to same material stack pile Strip, other materials and specification also can, as long as reach the in advance starting the arc, delay receipts arc, gap defect extension, improves end and becomes a useful person.
The welding method of a kind of Strip of the present invention, install run-on tab additional and receive arc plate, the starting the arc in advance on run-on tab during welding, receipts arc delayed by receipts arc plate, makes the starting the arc at weld seam both ends and receive arc gap defect extension, ensure becoming a useful person of end of welding bead, be applicable to all molten solder modes, be not limited to plate & strip production, the welding of any shape and specification, as long as make end defect extension ensure by which, better become a useful person in end.
During operation, prior preparation stack pile is with the cobbing two pieces (we are referred to as run-on tab and receive arc plate) of material, width suitable (according to weld jig size determine, so that be retained as suitable together with Strip), the section of polishing run-on tab, receipts arc plate, strip end is concordant, be put in the striking of strip weld bond and receive arc end, tight with solder opposite joint, welding wire can be sheared when excesssive gap and fill to make up.By run-on tab, receipts arc plate, and strip welding material is fixed together, the then starting the arc in advance on run-on tab, receipts arc is delayed by receipts arc plate and implements welding.After having welded, band welding end produces without gap.
Claims (2)
1. the welding method of a Strip, it is characterized in that when Strip molten solder, make two pieces of stack piles make run-on tab respectively with the cobbing of material and receive arc plate, by run-on tab, receive arc plate and strip end section polishing concordant, by run-on tab with receive the outside that arc plate is positioned over Strip weld, the starting the arc on run-on tab during welding, carry out Strip welding again, on receipts arc plate, receive arc, the end gap that welding process is produced after Strip welding, occur in run-on tab and receive on arc plate; After having welded, run-on tab and receipts arc plate are removed, arc gap defect is received in the starting the arc eliminating end during band welding.
2. the welding method of a kind of Strip according to claim 1, when it is characterized in that placing run-on tab and receiving arc plate, run-on tab and receipts arc plate weld with strip expects that opposite joint is tight, its gap filler wire.
