Abstract
The invention concerns a ceramic welding process in which a mixture of refractory and fuel particles is projected from an outlet at an end of a lance in a gas stream against a target surface where the fuel particles combust in a reaction zone to produce heat to soften or melt the projected refractory particles and thereby form a coherent refractory weld mass. A method of monitoring the distance between the lance outlet and the reaction zone is disclosed in which the reaction zone and at least part of the gap between that reaction zone and the lance outlet is monitored by a camera and an electronic signal is produced indicative of the distance ('the working distance') between the lance outlet and the reaction zone.
