Ntle le maemo a kaholimo a tikoloho, tikoloho e sebetsang ea likhokahanyo tsa tjheseletsa e tla phephetsoa ka matla ka lebaka la khatello e matla ea likhokahano tsa ba sebetsang masimong, ho tiea ha lisebelisoa tse nang le litšepe, thatafalo ea lisebelisoa tse hahiloeng, lebotho la khohlano le joalo-joalo.

Litlhokahalo tsa litšobotsi tsa ho ikopanya le maqhubu a phahameng

   Ka lebaka la litlhoko tse sebetsang tsa mabitso a ho kopanya a tjheseletso le moeli oa tikoloho ea ts'ebetso ea hlooho ea welding, litlhoko tse ikhethileng tsa litšobotsi li behiloe pele bakeng sa lisebelisoa tsa hlooho ea welding. Ha e le hlooho ea ho kopanya litšepe, lisebelisoa tsa eona li tlameha ho ba le tšebetso tumellanong le ts'ebeliso e sebetsang maemong a latelang:
