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.
Chart 1 Mark on welding method and penetration type

Mark	Welding method	Penetration type
MC	Shielded metal arch welding	CJP-complete joint penetration
MP		PJP-partial joint penetration
GC	Shielded arch welding Self-shielded arc welding	CJP-complete joint penetration
GP		PJP-partial joint penetration
SC	Submerged arc welding	CJP-complete joint penetration
SP		PJP-partial joint penetration
SL	Electroslag welding

 4.3. For the mark of single, double side welding and backing material type, please see the following chart 2
Chart 2 Single/double side welding and backing material type mark

Backing material type		Single/double side welding
Mark	Material	Mark	Single/double side welding
BS	Metal backing	1	Single side welding
BF	Other backing	2	Double side welding

4.4. Mark on each part size of groove, see chart 3.
Chart 3 Size mark on groove

Mark	Size of each part on groove
t	Thickness of welding plate(mm)
b	Groove root gap or gap between two members(mm)
h	Groove depth(mm)
p	Groove roof face(mm)
α	Groove angle(º)
