1. The welding environment of gasifier shall meet the requirements specified in the welding procedure code according to different welding methods.
2 welders shall carry out welding in strict accordance with the welding procedure code and welding procedure documents. After the welding of the weld is completed, the welder shall stamp the welder's steel seal on one side of the weld, and mark the weld that cannot be stamped.
3 the inspector shall strictly inspect the welding process code and the process code for weld appearance quality inspection. For the welding of pressure components, the welding process and weld appearance inspection record card shall be filled in according to the regulations. For welds with NDT requirements, the inspector shall go through the entrusted inspection procedures and conduct NDT according to the provisions of design drawings or technical documents.
4 generally, the welding inspector shall make welding quality statistics for welders every month and analyze the quality data.
5. The welding equipment shall be fixed by personnel and machine, and the equipment operation procedures shall be strictly observed to ensure the good technical condition of the equipment.
6 the ammeter, voltmeter, gas flowmeter and other instruments of welding equipment and the specification parameter regulating device with measurement verification requirements shall be verified regularly to ensure effectiveness.
