Guangzhou Steel tells 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.
It must be based on drawings, technical and quality standards, and characteristics of the coupling member, the corresponding assembly measures.
Should consider the possibility of welding, welding deformation is minimized, and easy to correct, in order to determine to take 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 shortening the margin after welding allowance.
All processing components should see its specifications, size, quantity meets the requirements, all parts and components to be corrected, connecting the contact surface and along the edge of the weld rust within a range of 30 ~ 50mm, burr, oil, ice should be clean and clear.
Where shaded parts after assembly, we should admit after passing through QC before welding or external shading. After assembling the first member, shall be subject to a comprehensive view of QC admitted after passing the assembly before proceeding.
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.
Factor structure should be based on the way, welding methods, welding sequence, etc., to determine a reasonable order of assembly, generally advised major parts, 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. All splice welds are full penetration welds of the fight, qualified 100% ultrasonic testing; thickness ≤8mm, by other means (X-ray or drilling, etc.) View. Guangzhou Steel
