Maintenance Welding

Maintenance Methods always cannot be the same as Erection / Manufacturing processes. In Erection / Manufacturing the processes methodical steps are preplanned and work is organised in a conducive atmosphere with well-laid out procedures, whereas in maintenance works time available to do the work will be limited and there may be constraints in space availability etc. coupled with unfriendly surroundings. Hence improved methods may have to be adopted to gain easy accessibility and to carry out the work quickly with minimum down time of the equipment. A typical example of the above viz. the window type welding technique adopted in wel^ling of certain inaccessible areas is narrated in the paper.
