Electric welding rod for gas shielded welding X80 grade steel oil, gas transmission pipe

The invention discloses a gas-shielded welding wire used for the production of grade X80 steel and oil and gas transferring. The gas-shielded welding wire comprises the following chemical compositions (according to the weight percentage): 0.08-0.12 percent of C, 1.40-2.0 percent of Mn, 0.30-0.70 percent of Si, larger than 0 and smaller than or equal to 0.015 percent of P, larger than 0 and smaller than or equal to 0.015 percent of S, 0.20-0.40 percent of Mo, 0.10-0.35 percent of Cu, 0.10-0.2 percent of Ti, 0.15-0.40 percent of Cr, 0.65-0.90 percent of Ni, 0.004-0.008 percent of B, 94.9-97.0 percent of Fe, and impurity for the residual; the gas-shielded welding wire is produced according to the production technique of common gas-shielded welding wire. The pipe used for production has the following welding seam performances: the tensile strength is 665-750MPa, the yield strength is 555-680MPa, the specific elongation is 20-29 percent, the hardness is 205-236HV10, the Charpy Impact energy is Akv(-10 DEG C)=230-262J, and the shearing area is 66-73; the Charpy Impact energy of the heat affected zone is Akv(-10 DEG C)=224-268J, the shearing area is 75-83, the performances are greatly superior to the requirements on the welding seam performance of the grade X80 steel pipe, the gas-shielded welding wire has excellent performances such as high strength, high toughness, good corrosion resistance, low hardness and the like which are similar to the performances of the pipe body, the security of pipe transportation can be effectively enhanced, and the service life of the pipe transportation can be prolonged.

Reused code matching inquiry method based on meaning

The invention discloses a reused code matching inquiry method based on meaning, which belongs to the technical field of computer software and includes: (1) requiring whether an ontology base has a domain ontology to be provided which reused codes belong to and building a domain ontology the reused codes belong to if the ontology base has no domain ontology to be provided, (2) performing abstract description based on meaning on the reused codes, (3) sending description information and domain information the reused codes belong to to a reused code management center for registering, (4) determining the domain ontology the requiring reused codes belong to according to the ontology base through a request end and performing meaning annotation on requiring requests, (5) performing abstract description based on meaning on the requiring requests after meaning annotation through the request end and sending the abstract description to the reused code management center for requiring, and (6) returning reused code abstract description information meeting the requiring requests to corresponding reused code requestor client sides through the reused code management center. The reused code matching inquiry method based on meaning improves project development efficiency and saves manpower and material resources.
