A pre-heating equipment 200 for a welding process. The pre-heating equipment 200 comprises: a pre-heater head 201 configured to direct gases to the weld components to be reacted; a pre-heater module 203, the module 203 comprising a gas inlet 301 for receiving a pressurised gas, and a gas outlet 302 for allowing the pressurised gas to flow from the module 203 towards the pre-heater head 201; and at least one gas conduit 204 configured to direct the pressurised gas from a pressurised gas supply 207 to the pre-heater module 203. The equipment 200 further comprises a gas pressure measurement means 206 for measuring the gas pressure, and a temperature measurement means for measuring temperature. The pre-heater module 203 is further configured to convert data from the gas pressure measurement means and the temperature measurement means into digital information. The pre-heater module 203 is configured to provide the converted digital information visually and/or audibly. |
