Some Process Indroduction Of Steel Structure Manufacture

1 Welding Process of Manual arc welding:

Preparation for operation → Arc welding (downward welding ,vertical welding, overhead welding, horizontal welding) → Weld line inspection

2 Connection Process of Torsional shear type high-strength bolt:

Preparation for operation → Select and match bolts → Assembly of joints → Temporary bolts of the device → High-strength bolts of the device → Tighten the high-strength bolts → Final inspection

3 Manufacturing Process of steel roof truss:

Processing preparation and blanking → Processing parts → Small device (small assembly) → General device (general assembly) → Roof frame welding → Support joint plate, purlin, angle device, welding → Product inspection → Rust removal, Paint&Number

4 Steel structure anti-corrosion coating process:

Base surface cleaning → Primer coating processing → Topcoat coating processing→ Inspection

5 Technical Process of steel structure fire-proof coating:

Preparation → Batching, mixing of Fire retardant coating → spraying → Inspection
