4J36(Invar) e fa'aaogaina pe a mana'omia le mautu maualuga, e pei o meafaifa'aili sa'o, uati, fua fetolofi maseisi, fa'avaa ata-mask televise, valve i afi, ma uati fa'amaneta. I le fuaina o fanua, pe a fai le fa'atonuga muamua (maualuga-sa'o) fa'asa'o maualuga e fa'atino, o le Aufaigaluega (leveling rod) e fa'aaogaina e faiInvar, nai lo laupapa, fiberglass, po o isi uamea. Sa fa'aogaina fa'alava invar i nisi piston e fa'atapula'a ai lo latou fa'alauteleina o le vevela i totonu o latou po'o.
4J36 faʻaoga oxyacetylene uʻamea, uʻamea eletise eletise, uʻamea ma isi auala uʻamea. Talu ai ona o le faʻaopoopoga o le faʻalauteleina ma le vailaʻau vailaʻau o le uʻamea e fesoʻotaʻi e tatau ona aloese ona o le uʻamea e mafua ai se suiga i le tuʻufaʻatasiga uʻamea, e sili atu le faʻaogaina o uʻamea faʻapipiʻi faʻapipiʻi Argon arc e sili atu ona i ai le 0.5% i le 1.5% titanium, ina ia mafai ai. faaitiitia porosity uelo ma ta'e.
