Technical Requirements for Rack Welding in Dongguan

Technical Requirements for东莞 Rack Welding

One: Dongguan's rack welding must ensure symmetry, balance, and verticality, manufacturing according to the specifications of the drawings.

During welding, the焊接surface must be free of defects such as false welds, gas pockets, slag inclusions, cracks, weld spatter, burn-through, arc craters, undercuts, arc strikes, and incomplete welds. The weld should be even and aesthetically pleasing.

2. The surface of the frame welding in Dongguan must be free of dents or unevenness.

3. Ensure the aircraft surface is polished for a smooth finish, and quickly clean off weld slag.

4. Ensure that after welding, the slag is quickly cleaned, and the surface layer is sanded to be smooth and even.

5. The production of the guide slot must ensure proper opening and closing, with a smooth surface layer that is level, without any highs or lows, and no opening and closing inconsistencies.

The bending of sheet metal components must be manufactured in accordance with the requirements of the design drawings. Components with arcs must be smooth, and the bending surface must be flat without any indentations or protrusions. Dimensional symmetry, parallelism, and perpendicularity must be ensured.

Post-welding treatment process

Welding completed, quickly clean the slag spatter from the weld seam surface, inspect the appearance and dimensions of the weld, and use corrective repairs promptly if the weld is uneven.

2. The weld seam should be smooth and symmetrical, with even and seamless junctions between welds and between welds and the base metal.

3. For components with partially enclosed structures, featuring multiple or long welds, it is necessary to promptly use methods such as hammering and vibration to relieve residual stresses after welding. If the parts require heat treatment, use heat treatment to eliminate the stresses.
