The proposed increase: <br>1. All welding subcontractor before construction work, required to obtain the qualified welding procedure related to and prepare welding operation instruction. <br>2. subcontractors need to prepare a pre-welding procedure for the owners and PMC audit, pre-welding procedure for examination and approval by the owners and PMC, subcontractors began to develop welding procedure and welding procedure qualification, owners and PMC welding procedure qualification process supervision of welding procedures for approval, only after confirming with the design requirements for construction. <br>3. unit production welding procedure and welding procedure qualification shall have appropriate qualifications, must be reported to the owners and PMC audit, after the approval of the owners and PMC for approval before commencing production. <br>4. sub-supplier before NDT operations shall prepare qualified NDT process planning and preparation of non-destructive testing work instructions. <br>5. All welders and corrosion mending personnel engaged in the engineering welding, corrosion Mending staff, NDT testing personnel should pass the exam owners and PMC organization, passing behind the prospective on the <br>post.

Suggested additions:<br>1. Before the construction of all welding work, the subcontractor shall obtain the relevant welding process procedures that are qualified for evaluation, and prepare the guidance for welding work.<br>2. The subcontractor shall prepare pre-welding process procedures for examination by the owners and PMC, and after the pre-welding process procedures have been approved and approved by the owners and PMC, the subcontractors begin to develop welding process procedures and welding process assessment, and the owners and PMC shall supervise the welding process assessment process and approve the welding process procedures. Confirm that the design requirements are met before they can be used for construction.<br>3. The unit that makes welding process procedures and welding process assessment must have the corresponding qualifications, must report to the owner and PMC for examination and approval, after the owner and PMC approval can begin production.<br>4. Before the subcontractor's non-destructive testing operation, it is necessary to prepare qualified non-destructive testing process procedures and prepare guidance for non-destructive testing operations.<br>5. All welders and anti-corrosion filling personnel, anti-corrosion repair personnel, NDT testing personnel engaged in welding of this project shall pass the examination organized by the owner and PMC, and pass the post-pass<br>Gang.

It is suggested to add:<br>1. Before the construction of all welding operations, the subcontractor shall obtain the relevant welding procedure specification qualified and prepare the welding operation instruction.<br>2. The subcontractor shall prepare the pre welding procedure specification for the review of the owner and PMC. After the pre welding procedure specification is approved by the owner and PMC, the subcontractor shall start to develop the welding procedure specification and welding procedure qualification. The owner and PMC shall supervise the welding procedure qualification process, approve the welding procedure specification and confirm that it meets the design requirements before it can be used for construction.<br>3. The unit making welding procedure specification and welding procedure qualification shall have corresponding qualification, which shall be submitted to the owner and PMC for review, and the production can be started only after the approval of the owner and PMC.<br>4. The subcontractor shall prepare qualified NDT process specification and NDT operation instruction before NDT operation.<br>5. All welders, anti-corrosion patching personnel, anti-corrosion patching personnel and NDT testing personnel engaged in the welding of the project shall pass the examination organized by the owner and PMC, and go up only after passing the examination<br>Post.<br>
