Guangzhou Steel teach you: construction steel components assembled provision

 

Assembly platform, mold, etc. should be smooth and firm, in order to ensure the accuracy of the assembly member.
Necessary reference to the drawings, processes and quality standards, and the characteristics of the coupling member, the corresponding assembly measures.
Should consider the possibility of welding, welding deformation is minimized, and easy to correct to conclude that taking one or more assembly assembly, that is, first assembled, welded into a number of parts, and were correct distortion, and then assembled into components.
Welding should consider shrinking margin after welding allowance.
All parts of the process should check its specifications, size, quantity meets the requirements, all parts and components to be corrected, connecting the contact surface and along the inner margin of the range of 30 ~ 50mm weld rust, burrs, oil, ice should be clean and clear.
Where the hidden parts after assembly, shall be subject to confirmation QC qualified to carry out welding or external hidden. After assembling the first member, make sure that after passing through the square QC sustainable assembled a comprehensive examination.
If students splice splice, in order to reduce welding stress, easy to correct deformed, should stitching, welding, the test, qualified after the correction, and then assembled.
Should be based on the structure of the way, welding method, welding sequence and other factors, determine a reasonable order of assembly, generally advised first part, after minor parts, the first intermediate ends after the first horizontal-vertical, outside after the first interior, in order to reduce distortion.
When the clamp assembly, when the removal of the fixture can not be shot down with a hammer, cut gas cutting applications, they are not to damage the base material of the remaining burr, slag grinding should be clean.
Steel splice width of not less than 300mm, length less than 600mm; steel splice length of not less than 2 times the cross-sectional diameter or the long side, and not less than 600mm everything are full penetration welding seam 100% ultrasonic flaw inspection of weld penetration of the fight. ; thickness ≤8mm, by other methods (X-ray or drilling, etc.) check.
