Abstract
The invention discloses the field of welding technologies, in particular a welding method of congeneric metals of a composite metal board. The invention aims at providing a welding method of the composite metal board, which is capable of causing a welded joint to have good forming, no welding vice and improved tensile strength. The welding method comprises the following steps of beveling, preheating, welding, cooling and the like, and has the characteristics of high production efficiency, simple operation and the like.
Description
Technical field
The present invention relates to a kind of welding technology field, especially a kind of composition metal plate intermetallic welding method of the same race.
Background technology
Metal price is widely different now, and the metal price that has is very high, and the metal price that has is cheap; Often the metal price of function admirable wants high, and their performance of different metallic also is inequality, and the product of enterprise production is in order to reduce cost now; Use composition metal plate on the increasing product, this composition metal plate is processed one by the different metal lamination, and the metal level major part is two layers; Certainly have plenty of three layers, the intermediate layer is low-cost parent metal, and other metal is used on two top layers.Sheet metal with above-mentioned is processed cylindrical shell, is rolled into tubular to sheet material so, again with being welded; Perhaps a clad metal sheet area is little; Will be spliced into more large-arealy with at least two composition metal plates, also be welded usually, present welding all is to weld with welding wire in the junction; But such mode makes the plate property of weld relatively poor, and particularly tensile strength is not enough.
Summary of the invention
The objective of the invention is to overcome the deficiency of prior art, the welding method that a kind of joint moulding that makes welding is good, do not have the composition metal plate that welding defective, tensile strength improve is provided.
The technical scheme of the welding method of composition metal plate of the present invention is design like this: the first step; Bevel; Promptly the joint to composition metal plate to be welded carries out bevel; Groove symmetry and size that each composite board of butt joint is opened are identical, and the bevel angle of described joint is the 50-60 degree; As preferably, bevel is that the composition metal plate upper and lower surface is provided with bevel angle 50-60 degree simultaneously, and the basic unit of upper and lower surface part symmetry; In second step, preheating to being arrived at least 10 ℃ by the weldering METAL HEATING PROCESS, is carried out next step welding then; The welding of the 3rd step promptly according to the difference of metal level, is selected corresponding welding wire; And adopt arc welding to weld, when welding, fill corresponding protection gas, be lined with metal gasket at the joint back side during welding; Welding direction is vertical upwards, and each bead thickness is no more than 13mm; In the 4th step, cooling promptly naturally cools to room temperature.
Like the composition metal plate model is that SA265 welds, and described composition metal plate SA265 is by carbon steel layer and non-ferrous metals lamination system and be integral, and the model of described carbon steel is that SA516-70 is a basic unit; The model of non-ferrous metals is that SB443-NO6625 is a composite bed, carries out the first step successively by above-mentioned welding method; Bevel; Composition metal plate is carried out the upper and lower surface bevel, and the groove of upper and lower surface is identical at the thickness of basic unit, and groove is the 50-60 degree up and down; Best with 55 degree, can do suitable adjustment according to thickness certainly; Second step, preheating, the welding of the 3rd step for the welding of basic unit's part, is adopted self-protection flux-cored wire arc welding FCAW, and welding wire is selected E71T-1 for use, and protective gas is selected 100%CO for use
2, gas flow 18-24L/min number, when partly welding for basic unit, the time interlayer temperature be controlled in 200 ℃; Consumable electrode argon shield weldering GMAW is adopted in the welding of non-ferrous metals layer segment, and welding wire is selected ERNiCrMo-10 for use, and protective gas is selected 99.999%Ar, gas flow 18-24L/min, and the time interlayer temperature be controlled in 100 ℃; Be lined with metal gasket at the joint back side during welding, welding direction is vertical upwards, and each bead thickness is no more than 13mm; In the 4th step, cooling promptly naturally cools to room temperature.
From above-described, can find out 1, this method appearance of weld is attractive in appearance, arc stability is good, splash less and particle tiny, the welding wire deposition rate is fast, deposition efficiency and productivity ratio are all higher; Preset a kind of metal solder liner along the joint back side when 2, welding, guaranteed that root of joint through welding and back of weld are shaped; 3, simultaneously simple to operate.
Description of drawings
Fig. 1 is a welding sketch map of the present invention.
The specific embodiment
Below in conjunction with accompanying drawing the present invention is done further elaboration.
The composition metal plate welding method may further comprise the steps:
1, selection: composition metal plate is selected SA265 for use, thickness of slab 17.5mm, and wherein the thickness of basic unit 1 is 9.5mm, the thickness of composite bed 2 is 8mm.
2, welding process is following:
Before the welding, at first composite board SA265 port is arranged to groove 3 and following groove 4, bevel angle is 55 °, about last groove 3 and following groove 4 joint root minimum clearance 1mm; Adopt basic unit's part of self-protection flux-cored wire arc welding FCAW welding SA265 then, welding wire is selected E71T-1 for use, and protective gas is selected 100%CO for use
2, flow 18-24L/min supplies gas; Then adopt consumable electrode argon shield weldering GMAW welding composite bed part, welding wire is selected ERNiCrMo-10 for use, and protective gas is selected 99.999%Ar, and flow 18-24L/min supplies gas; This composition metal plate has 3 welding beads 5, and each welding bead electrical characteristics is no more than 13mm with each welding bead 5 thickness of welding skill.
3, interpretation is chosen the stretching test samples according to AWS D1.1 and U.S. material and experiment association criterion (ASTM A370), obtains sample maximum load 200kN; Tensile strength 600Mpa; Invalid position meets the requirement of welding conditions in the heat affected area, and the result of guided bend test also is qualified in addition; Fill metal and mother metal good knitting in the macro-etch test, macroscopical section is not found weld defects such as incomplete fusion and crackle.
