1. Umthungo ohlanganyelwe (okungukuthi, umthungo owakhekayo) awunawo imiphetho engalungile noma imiphetho engalungile ingaphansi kwevelu elishiwo. Ngokuvamile, inani lemiphetho engalungile lingaphansi kuka-8% wobukhulu bepuleti, futhi umkhawulo awukho ngaphezu kuka-1.5mm.

2. Ukuqinisekisa ukuthi i-weld inokujula okufanele kokungena kanye nenani le-deposition, kuyadingeka ukuqinisekisa ukuthi ayiqhekeki noma ayishi ngemuva kokushisela, futhi kuyadingeka ukulawula ukuphakama kwe-weld ukuze ukuphakama kwe-weld i-weld yangaphandle ngeke ithinteke.

3. Ubuhlalu obushiselayo buyaqhubeka futhi bubunjiwe ukuze kuqinisekiswe ukushisela kwangaphandle ngemva kwalokho.

4. Umthungo we-welding awunawo amaphutha njengokuphambuka kwe-welding, ama-pores, imifantu, ukufakwa kwe-slag, ukushiswa kwe-welding kanye ne-back welding, futhi ukuphambuka kwesikhungo kusuka kumthungo wokushisela kuyadingeka ukuba kube ≤1mm.

5. Akukho ukushiswa kwe-arc, ukuchaphaza okuncane, futhi akukho thonya ku-bevel nangaphezulu kokuphela kwepayipi.

6. I-welding seam ihambisana nesisekelo sensimbi, futhi izakhiwo ezingokomzimba nezamakhemikhali zensimbi ye-welding seam zihlangabezana nezidingo.
