The welding process first welds the root, the post-weld transition layer, the surface root weld is applied with a large current, <3.2 electrode is welded to ensure penetration, no defects, and the defect is found to be polished and re-welded by a polishing machine. The root weld is 1/5 of the diameter of the circumference, the transition layer is 3/5 of the diameter of the circumference, and the surface layer is 1/5 of the diameter of the circumference.
Each layer of welding is inspected to ensure the quality of the welding. Each layer of the weld shall be inspected. After the root inspection is passed, the transition layer shall be welded. After the transition layer is passed, the surface layer shall be welded. In addition, the welding shall be inspected at any time during the welding process. Quality, found to be defective immediately removed re-welding.
Selection of welding energy and control of interlayer temperature The transition layer and surface layer welding use small line energy, multi-pass welding, and the interlayer temperature is controlled below 50e. Welding parameters see welding parameters welding part welding diameter mm welding current A welding voltage V welding speed cm / s root 3.2110140221012 transition layer 41150 022 251 214 surface layer 41501 022 251 2511146.5 quality measures preheating the workpiece before welding, preheating temperature control around 150e, can effectively prevent crack. After welding, due to the cold brittleness of No. 50 steel, it is easy to produce hydrogen-induced cracking. Insulation measures should be taken. Winding with 50mm of <20mm asbestos rope, keeping it for 2h3h, slowly cooling it to room temperature, then assembling it, in order to ensure the verticality of the bolt after welding. Degree, the welding should be carried out circle by circle.
Non-destructive testing performs a coloring test on the surface layer in accordance with JB4730-9. The economic benefit analysis adopts the cost of the overall replacement process: spare parts cost 20,000 yuan; construction and auxiliary materials cost 60,000 yuan; construction period 10d. The cost of welding repair method: spare parts cost 0 million yuan; construction and auxiliary materials fee 20,000 yuan; construction period 2d. From the above comparison, it can be seen that the welding method can greatly reduce the engineering cost and construction period, and at the same time, it has won time for the manufacturer and created certain economic benefits.
Conclusion By adopting the above process measures, the triple-gear bolts of the China Plate Factory have fully met the requirements for use after welding, and the operation status has been good since the recovery of production. It can be seen that for the welding of special steel materials, as long as the appropriate welding materials are selected and a reasonable welding process is adopted, excellent welding quality can be obtained to meet the requirements of users.
The pair of bolts should be aligned with the upper and lower centers to ensure the verticality of the upper part. The misalignment amount should not exceed 1mm. It can be inspected by wire hammer and square rule. When the positioning welding is docked, the spot welding is carried out at the root with <3.2 electrode, and the positioning is strengthened in the upper spot welding fixture. Fixtures can be made of N63 angle steel and welded with J422 welding rod.
