welding technology
Collapse required equipment
A set of manual electric welding equipment, a handle type angle grinder, an electric hammer and a plane ruler.
Preparation before folding welding
1: Check and commission equipment to ensure normal operation of equipment; 2. Preparation φ 4.0J402 welding rod should be dried at 300 ¡æ - 350 ¡æ for one hour.
Folding welding process
1: Assemble the cone and large flange together according to the drawing requirements, and then divide the large flange into 8 equal parts. 2. Because the flange is thick and the groove is large, the welding is symmetrical in sections and multi-layer.
Folding weld quality
The weld strength is required to be at least that of the base metal. The weld surface shall be flat and smooth without burn through, air hole, weld leakage, slag inclusion, undercut, incomplete welding and other defects. The surplus height is less than 2mm.
Notes on folding
1: During backing, J506 electrode must be used for manual surfacing and low current welding. Welding shall be carried out in strict accordance with the welding process. 2. After each welding position is completed, the deformation of the flange plane shall be checked with a level gauge. 3. While welding, hammer the weld with air hammer to eliminate stress.
