The meeting for review of Welding Procedure Qualification (WPQ) test for 132m steel trusses for Xi'an-Chengdu PDL Grand Bridge over Xi'an-Baoji PDL was held by Tianjin New Asia-Pacific Engineering Construction Supervision Company in the 4th meeting room in CRBBG on June 26. Experts and representatives from Xi'an-Chendu PDL Company, China Railway First Survey & Design Institute Group, Northwestern Polytechnical University, Chang'an University, Baoji Petroleum Machinery Plant, China Railway 11th Group and CRBBG attended the meeting.

The attendees listened to the WPQ Test Report made by CRBBG for fabrication of 132m steel trusses for Xi'an-Chengdu PDL Grand Bridge over Xi'an-Baoji PDL. The expert team came to an agreement after serious discussion that, the WPQ test report submitted by CRBBG had detailed content and reliable data; the tests for 19 welded joints covered all joint types in the design document; and all mechanical performance indexes met the specification requirements, thus it could be the basis for preparing the Welding Procedure for this project.

At the meeting, CRBBG Chief Engineer Ji Minting, on behalf of the company, addressed that CRBBG would accomplish the fabrication of steel trusses for this project with further strengthened management, deliberate arrangement, optimized processes, elaborate production as well as high quality and high efficiency.
