Izindlela ze-Surface NDT zezimiso zokukhetha insimbi yomthungo oqondile: ipayipi lensimbi kazibuthe kufanele lisetshenziswe ekuhlolweni kwezinhlayiya kazibuthe;insimbi engeyona i-ferromagnetic kufanele isetshenziswe ekuhlolweni kokungena.Ukulibaziseka kokuqhekeka kokuthambekela kwamalunga ashiselwe, indawo engaphezulu kufanele ibe ukuhlolwa okungabhubhisi ngemuva kokupholisa kwe-welding isikhathi esithile;shisa kabusha ukuthambekela kokuqhekeka kwamalunga ashiselwe, indawo engaphezulu kufanele ibe ekuhlolweni okungabhubhisi kanye nokwelashwa kokushisa kwangemva kwe-weld kanye ngayinye.

Izinhlelo zokusebenza zokuhlola ezingabhubhisi ngokuhambisana nezidingo ezijwayelekile ezithola izinto nezinhlelo zokusebenza ngokujwayelekile ngale ndlela elandelayo:
(1) Indawo engaphandle yokuhlolwa kwekhwalithi yezinto ze-tube.
(2) Ukutholwa kwesici esibalulekile se-butt weld surface.
(3) Ukutholwa kwesici esibalulekile se-fillet surface.
(4) Okubalulekile kwe-socket weld kanye ne-jumper tee yegatsha lokutholwa kokukhubazeka kwepayipi.
(5) Ukutholwa kwesici sokugoba kwepayipi.
(6) Izinto ezisetshenziswayo zivame ukucisha ukutholakala kwamajoyinti ashiselwe ama-groove amakhulu.
(7) Izinga lokushisa lomklamo lingaphansi kukaziro noma ipayipi lensimbi engagqwali elingeyona i-austenitic beveling litholwa 29 degrees Celsius.
(8) Izinhlinzeko zokushisela okunezinhlangothi ezimbili ngemva kokutholwa kokushisela kwe-weld gouging
(9) Uma usebenzisa i-oxyacetylene flame cutting jig welded amapayipi ingxubevange ukuthambekela kokuqina lapho ugaya ukutholwa kokukhubazeka.
