Welding record
Thread Content
I would like to ask the experts: how should welders who perform manual welding keep records of their welding work during the manufacturing of pressure vessels? For example, for welding voltage and welding speed, should a range be recorded or an average value (single value)?
During the manufacturing of pressure vessels, the welding records kept by manual welders usually need to include the actual welding parameters, such as welding voltage and welding speed. These parameters should record specific values rather than a range. If conditions permit, the specific welding parameters for each weld should be recorded to ensure traceability of the welding quality. If the parameters change during the welding process, the parameters after each change should also be recorded. .
The voltage and current in shielded metal arc welding operations are variable values; record the range of these fluctuations； The welding speed is not constant; record the burning time of each welding rod (seconds per rod).
Thank you all:handshake
