Abstract
The invention discloses a method for welding terminal circular seams of compound steel plates. The method comprises the following steps: 1), assembling two compound steel plates and protecting the rear surfaces by argon; 2), welding a compound layer by manual argon tungsten-arc welding, and selecting an H0Cr21Ni10Tiphi2 welding wire as a welding material, wherein the welding condition is as follows: the current is 100-120 A, the voltage is 13-16 V, the welding speed is 12-15 cm/min, and the air flow is 8-10 L/min; 3), selecting an A302 welding rod as a transitional layer, and controlling the welding current to be 140-160 A, the voltage to be 23-25 V and the welding speed to be 15-18 cm/min; 4), selecting the A302 welding rod as a basis layer, and controlling the welding current to be 140-160 A, the voltage to be 23-25 V and the welding speed to be 15-18 cm/min; 5), after welding, making an appearance test and carrying out 100% RT radiographic inspection detection; and 6), making a mechanical property test and an intercrystalline corrosion test according to steel pressure container welding procedure qualification. According to the method, the 100% RT radiographic inspection detection is carried out after welding, the defects of cracks, air holes, poor fusion and the like are not found after the detection, and the mechanical property test and the intercrystalline corrosion test meet the requirement of the steel pressure container welding procedure qualification.
Description
Technical field:
The present invention relates to welding method, relate in particular to the welding method of a kind of clad steel plate terminal circumferential weld.
Background technology:
A kind of pressure vessel, its material of main part are that promptly multiple layer stainless steel 06Cr18Ni11T of clad steel plate and the mild steel Q345R of basic unit form, and this product does not have manhole and has only hand hole; The terminal circumferential weld can't be accomplished the basic demand of composite plate welding: the basic unit of weldering earlier, back weldering transition zone, the requirement of the multiple layer of weldering at last; If the multiple layer of weldering earlier, melting welding carbon steel metal on transition zone, alloy weld seam in the formation; The about 2.5mm of hardenability band, the maximum hardness value is prone to produce weld crack approximately greater than 460HV.
Summary of the invention:
It is good to the purpose of this invention is to provide a kind of welding quality, the welding method of the clad steel plate terminal circumferential weld that mechanical property test and Huey test are all qualified.
The present invention is achieved in that the welding method of clad steel plate terminal circumferential weld, it is characterized in that: may further comprise the steps:
1), two clad steel plate groups to after, carry out back-protective with argon gas;
2) argon tungsten-arc welding is first, by hand welds multiple layer, and welding material is selected H0Cr21Ni10Ti Φ 2 welding rods for use, and welding parameter is: electric current 100-120A, voltage 13-16V, speed 12-15cm/min, gas flow 8-10L/min;
3) weld transition zone, again, welding material is selected the A302 welding rod for use, and welding parameter is: electric current is 140-160A, and voltage is 23-25V, and speed is 15-18cm/min;
4) weld basic unit, at last, welding material is selected the A302 welding rod for use, and welding parameter is: electric current is 140-160A, and voltage is 23-25V, and speed is 15-18cm/min;
5), welding finish carry out appearance test after, carry out the 100%RT radiographic inspection and detect;
6), carry out mechanical property test and Huey test according to " steel pressure vessel welding technology evaluation ".
The present invention's welding finishes and carries out the detection of 100%RT radiographic inspection, and flawless is found in the flaw detection back, defectives such as pore, incomplete fusion, and mechanical property test and Huey test all meet " steel pressure vessel welding technology evaluation " evaluation requirement
.
The specific embodiment:
The welding method of clad steel plate terminal circumferential weld is characterized in that: two clad steel plate groups to after, carry out back-protective with argon gas; Argon tungsten-arc welding weldering earlier is multiple layer by hand, and welding material is selected H0Cr21Ni10Ti Φ 2 welding rods for use, and welding parameter is: electric current 100-120A, voltage 13-16V, speed 12-15cm/min, gas flow 8-10L/min; Weld transition zone again, welding material is selected the A302 welding rod for use, and welding parameter is: electric current is 140-160A, and voltage is 23-25V, and speed is 15-18cm/min; Weld basic unit at last, welding material is selected the A302 welding rod for use, and welding parameter is: electric current is 140-160A, and voltage is 23-25V, and speed is 15-18cm/min; Strict control penetration ratio can not be used slag hammer and carbon steel wire brush; Welding finishes and carries out carrying out the detection of 100%RT radiographic inspection after the appearance test; Defectives such as result of detection flawless, incomplete fusion, pore, slag inclusion; Take a sample to process according to " steel pressure vessel welding technology evaluation " JB4708-2000 then and do mechanical property test and Huey test, all meet the evaluation requirement through test.After the product welding, carry out hydraulic pressure, airtight detection is all qualified.
