I.Steel plate cutting
The H section  steel plate should be checked again by the factory and shall be applied under the condition of up to design and specified requirements after checking. Steel plate cutting should be aimed at quality guarantee and material saving. For each process like plate cutting,H type assembly, components assembly and pre-assembly should be carried out by profession setting-out worker precisely on processing surface and assembly sample plates.To guarantee the accuracy of the components'geometrical dimension,tolerance of form and position, angle and contact surface,inspection is necessary by inspector after setting out.In order to ensure the cutting quality,the surface of the ultra-thick plate is subjected to the surface carburizing hardness test before cutting.The CNC cutting equipment is preferred for cutting.The high purity 98.0% acrylic gas and 99.99% liquid oxygen gas are used to guarantee the smoothness and flatness of the cutting surface without notches and slags.The groove is cut by a special imported cutting machine.

Process, fabrication and quality control standard on welding groove/beveling of steel structure
1. Purpose
To ensure the welding quality, meeting up the technical requirements of welded members and improve the standardization of our fabrication, we specially formulate this regulation.
2. Application scope
This manual apply for the design, fabricate and inspection of groove joint in terms of manual arc welding, CO2 arch welding, mixed gas arch welding, submerged arc welding and electroslag welding.
3. Design of welding groove
3.1 Key points on design welding groove:
In order to obtain quality groove, it is necessary to choose appropriate form of groove. The option of groove mainly depends on the thickness of base metal, welding method and craftsmanship requirements.The followings are the factors we need to consider:

1. minimize the amount of filler metal
2. easy for beveling
3. in convenience for welding operation and slag removal
4. After welding stress and deformation should be as small as possible

3.2 Groove direction:
We will consider the following factors for the groove direction:
A)in favor of welding process and removing slag and leave enough space for welding process on the fusion face
B)minimize the times of flip-flop during welding
C)way of fit-up in actual welding

3.3. Regulation on groove direction of members:

3.3.1 Butt welding on H section rafter/column (when CJP-complete joint penetration and single side fusion is required)
1) When there is no welding backing, the groove orientation on flange plates should be same and falls on the direction in favor of welding on web plats(same rules apply for the PJP situation). Please refer to illustration 1

2)When there is welding backing, we require the groove direction being outward for the flange plates(opposite direction for web plates) and still falls on the direction in favor of welding on web plates. Please refer to illustration 2
3)Butt-welding on construction site:we require all the grooves should be bevelled on the upper rafter/column when it comes to bolt connection for web plates(see illustration 3). For the scenario of welding on web plates, please refer to the illustration 4.
3.3.2 Box column(groove on itself).See illustration 5
4. Welding groove form
4.1. Mark on form and size of welding joint groove:
Example: Shielded metal arch welding, complete joint penetration, butt welding, I shape groove, welding backing and single side weld would be marked MC-BI-BS1
4.2. For the mark of welding method and penetration type, please see the following chart 1.
