Perfect Quality Assurance System

1. Personnel Qualification Control

1) Professional technical personnel pass through training. We select experienced personnel.

2) Operators of main equipment shall receive both internal and external training, take appointment with certificates and shall be arranged in certain posts.

3) All kinds of welders hold qualification certificates of corresponding welding methods.

4) Both quality control and non-destructive testing personnel have obtained the qualification certificates issued by the industry.

2. Material Control Technology

1). According to the production characteristics of different steel factories, develop different retest and sampling methods and control raw material quality well.

2). Effectively improve the steel plates’ anti-lamellar tearing performance according to steel plate rolling principle.

3). Implement raw material texture color batch and factory numbering systems and track raw material quality, so that manufacturers and quality warranty booklets of raw materials can be traced from finished products.

3. Disassembling Technology of Complex Mechanism

1) Disassemble complex mechanisms reasonably according to the shrinkage and deformation principle of welding, effectively eliminating and reducing welding deformation and welding stress.

2) Reasonable disassembly can reduce welding deformation, so as to minimize mechanical and flame correction and effectively ensure physical properties of base metal.

4. Welding Technology

1) Use double-wire and three-wire submerged arc welding, greatly improving the welding efficiency;

2) Use special welding process and process control, conduct high-strength thick plate welding and meet requirements of special engineering;

3) Groove design effectively avoids lamellar tearing and welding deformation in second half welding.

5. Welding Deformation and Contraction Control Technology

1) Arrange welding sequence reasonably, make use of deformation balance principle, and avoid and reduce welding deformation;

2) Use pre-deformation and anti-deformation to avoid and reduce welding distortion;

3) Adopt pre-release welding shrinkage according to experience, prevent size error due to welding shrinkage and ensure the site installation size.

6. Hole Processing Technology

1) Make full use of advanced CNC machining equipment and improve group hole accuracy.

2) Adopt pre-release welding shrinkage according to experience to ensure the hole’s linking size accuracy;

3) According to the requirements of special structure, use heightening techniques through special process, eliminate accumulated errors during the processing process and ensure the site installation size;

4) Manufacturing of important structures should combine the actual installation size of the site; and the adoption of pre-adjusting value effectively eliminates production and installation errors.

7. Process Control Technology

According to the characteristics of special components, develop special control procedures, implement effective control to the whole structure processing process, and timely adjust blanking and assembly size.
