1. Qaphela indawo yokufaka i-welding: Uma isihlalo sokugoqa siyisakhiwo sefreyimu yensimbi, kufanele kuqashelwe ukuthi indawo yokushisa kufanele ibe bushelelezi futhi ingabi nama-voids, futhi ukugqoka kufanele kubonakale kufana nokuthambile.
2, qaphela ubukhulu bepayipi yensimbi: Uma isihlalo esigoqayo siyipayipi ye-aluminium alloy, ubukhulu bepayipi yensimbi bungaba ngu-1.2 mm, futhi akukho ukungcola.
I-3, qaphela izinga lokuqina: bheka ikhwalithi yonke yefreyimu, ungasebenzisa izandla zombili ukugubha umkhiqizo emuva naphambili, ukuwunyakazisa, futhi uchaze ngokuqinile ifreyimu.
4, naka ikhwalithi yendwangu: ukuthenga isikhumba ungasebenzisa-ukuncinza kweminwe emibili ukuze udonse idonse, uzizwe unamandla, ukululama okuhle kungcono kakhulu.
I-5, zama ukuhlala: zama ukuhlala phansi futhi uqonde izinga layo lokunethezeka, i-angle ngayinye kufanele ishintshwe, bese uthenge emva kokuzimisela.
