Tests, destructive and non-destructive quality control of welded steel structures

Tests, destructive and non-destructive quality control of welded steel structures

Perform technical inspection and quality control of materials, manufacturing and welding of metal structures

1 - advice and monitoring وبازرسی the direction of the preparation of documents, quality control, welding included (maps, fittings, fusion, etc. specific instructions, welding WPS, etc. instructions testing, welding, etc., which by the manufacturer is produced).

2 - advice and نطارت and operation inspection construction based on standard AWS.D1.1 and regulations, surgical and topics, Bylaws, National building regulations in Iran, including the following steps:

2-1 - the authenticity of material consumed (steel sheets, etc. profiles, steel, etc. rebar, etc. bolts, etc. material welding, and....)And, if necessary, tests for mechanical and متالوژیکی and testing, the lack of ductility of steel .

2-2 - کنرل steps, cuts, cold and warm at the time of construction .

2-3 - controlled stages of assembly and pre-Assembly members, metal structure and تلرانسها and رواداریهای allowed.

2-4 - control of the welding parameters important welding process, electrode, manual, powder, etc. welding with گازوسایر conventional methods" .

2-5 - control inspects heating and de-stress "as needed" .

2-6 - control and monitoring of material consumption and the authenticity of their consumption in جوشکاریها .

2-7 - dimensional control after welding due to پیچشهای possible at the time of welding .

2-8 - types of tests, non-destructive includes: inspection چشمیVT, etc. inspection the fluids نافذPT the ... inspection, magnetic particle MT, etc. inspection with ultrasonic waves, or ultrasonic, UT, etc., or, if necessary, inspection of industrial radiography with isotopes of radioactive RT. In accordance with the table 10-4-1 topic tenth, Bylaws, National building regulations .

2-9 - control operation drilling and flange storage .

2-10 - control operation Alarm debugging, and coloring industrial.

3 - advice and monitor packaging operations and Shipping (loading and time setup) after the construction of the members and prior to installation .

4 - the issuance of a certificate of authenticity, the quality of the members of the structures built for the installation .

5 - نطارت and inspection operations install the structures to build based on standard AWS.D1.1, Bylaws, surgical and topics, Bylaws, National building Iran includes the following steps:

5-1 - layout of the correct organs before and after transportation to the location of the workshop installation .

5-2 - dimensional control, etc. therein. twisting, bending, and... members at the time of installation .

5-3 - control operation, assembly and رواداریهای allowed.

5-4 - control mounting members with screws, grips and controls observing the amount of correct twisting (Torque) with the use of ابزاریکه contractor install جهتاینکار used.

5-5 - control types جوشکاریهای site workshop install .

5-6 - test and non-destructive inspection جوشکاریهای on-site workshops .VT,PT,MT,UT,RT . ( If needed)

6 - The preparation booklet, the ultimate of all kinds of documents control during the construction and installation, and reliable delivery, after the completion of the project that led to the issuance of the certificate of authenticity of the structures installed will be.

7 - the issuance of a certificate of authenticity, quality, structures
