Cov yam ntxwv thiab daim ntawv thov
AWS A5.1 E7018-1 H4 Cov pas nrig vuam, cov hlau vuam electrode yog cov hlau-hmoov qis hydrogen hom electrode rau txhua qhov chaw vuam ntawm 490N / mm2 qib siab tensile hlau. Nws yog tsim los rau ib qho thiab ntau daim ntawv thov hla. Cov khoom muaj qhov zoo welder thov thiab tsim cov arc ruaj khov nrog tsawg spatter tiam. nws tsim cov hlau vuam nrog cov khoom siv kho tshuab zoo heev thiab cuam tshuam toughness ntawm qhov kub qis (-45 ℃) thiab qis diffusible hydrogen. Nws cov yam ntxwv ua rau cov khoom tsim nyog rau cov hlau tsis tshua muaj hlau, nruab nrab carbon hlau, hnyav hlau phaj, cam khwb cia hlau, txhuas tua hlau ntawm LPG thiab tshwj xeeb tshaj yog rau kev vuam ntawm cov hlau nrog tsis zoo weldability.

Cov lus qhia txog kev siv:
1. Tshwj tsis yog tias qhov chaw khaws cia tau ruaj khov thiab cov khoom ntim tsis puas lawm, peb xav kom koj ziab cov electrodes ntawm 350-400 ℃ li 1-2 teev ua ntej siv.
2. Siv txoj kev rov qab-kauj ruam kom tiv thaiv cov qhov cua ntawm qhov arc pib.
3. Kev tswj kom luv luv ntawm qhov arc yog qhov pom zoo kom tiv thaiv kom tsis txhob muaj dej noo.
