Can anyone describe me what is âBUTTERINGâ stands for in welding joint. If it is done before depositing the weld metal on job, is it necessary to remove the same by back chipping. Mr. Das, Buttering is a technique in which weld is applied to the surface in order to acheive desired properties or required dimensions. For example in fit-up/butt joint, if distance between two butting members is excess, buttering is done on one member to reduce the gap.
1 Flux-cored arc welding (FCAW) - almost identical to MIG welding except it uses a special tubular wire filled with flux; it can be used with or without shielding gas, depending on the filler.elding is a fabrication or sculptural process that joins materials, usually metals or thermoplastics, by causing fusion, which is distinct from lower temperature metal-joining techniques such as brazing and soldering, which do not melt the base metal.
