GEH-SL6 ke mofuta oa tjheseletsa e holimo bakeng sa valve ea enjene, lehare la turbine, mocheso o phahameng le valve ea khatello e phahameng, mochini o chesang o chesang le likarolo tse ling tsa mocheso o phahameng oa ho hanyetsa le likarolo tsa ho hanyetsa kutu. Ts'ebetsong ea welding, e le hore e ka kopanngoa ka thata le substrate, ho hlokahala hore ho kenelle ka botebo ho kena. Ka hona, ho ka sebelisoa mokhoa o mokhuts'oane oa welding oa arc. Taba ea bobeli, molemong oa ho rarolla bothata ba letamo le tebileng le lisebelisoa tse feteletseng tse qhibilihang ka har'a weld nakong ea welding e khuts'oane ea arc, sekhahla sa dilution se phahame. Ho haella ha likarolo tse sebetsang karolong ea weld ho fokotsa bothata ba ho hanyetsa ho apara. E tlameha ho sebelisa mokhoa oa ho etsa li-multiple-layers. Ka tsela ena, ha se feela likarolo tse sebetsang hantle le ho itšoarela ho hanyetsa mokokotlong oa backsurfacing ho eketsa lera ka lera.
