I-GER-N27L kunye ne-GER-N27 esiyivelisayo zombini i-electrode yensimbi ephantsi ye-hydrogen sodium-coated low-temperature kunye ne-Ni content ye-2.5%, ehlala isetyenziselwa i-welding ASME SA-203 GrA / B kunye ne-09MnNiDR. Iimodeli ze-GER-N27L kunye ne-GER-N27 esebenzayo ngoku i-GB/T5117-2012 yi-E5015-N5 P/E5015-G P kunye ne-E5515-N5 P ngokulandelanayo, ehambelana namabakala "welding Materials Product Handbook" epapashwe nguMashini. Ishishini Press. Kwi-W707 kunye ne-W707Ni, iipropati ezibonakalayo kunye neekhemikhali zetsimbi egciniweyo yee-electrode ezimbini zifaniswa ngolu hlobo lulandelayo.

Inokubonwa kwitheyibhile engentla ukuba i-chemical composition C kunye ne-Si yensimbi egciniweyo ye-GER-N27 (W707Ni) iphezulu kancinane kune-GER-N27L (W707). Ngoko ke, ngokwamandla, i-GER-N27L (W707) yeyomgangatho we-electrode ye-490MPa enamandla aphantsi. I-GER-N27 (W707Ni) yinqanaba, kunye nokusebenza kwempembelelo ye-GER-N27L (W707) ingcono kancinane kune-GER-N27 (W707Ni), kodwa kwizicelo eziphathekayo, i-GER-N27L (W707) kunye ne-GER-N27 ( W707Ni) impembelelo Uvavanyo lwamkelwa ngokubanzi ngokwesalathiso se -70°C okanye -75°C.

I-GER-N27L kunye ne-GER-N27 ine-weldability egqwesileyo yonke indawo xa i-welding ASME SA-203 GrA / B okanye i-09MnNiDR yentsimbi (njengoko kubonisiwe kulo mfanekiso ungasentla ukwenzela ukwakhiwa kwe-welding seam yee-electrode ezimbini), kwaye ngokubanzi kucetyiswa ukuba amandla omgca we-welding akufanele adlule i-35kJ / cm, ukuze ufumane isakhiwo esihle kakhulu esilawulwa yi-acicular ferrite. Xa i-GER-N27L (W707) isetyenziswa kwisixhobo esidinga ukucinywa kunye nonyango lobushushu obushushu + unyango lobushushu, ngokuqhelekileyo kukufumana ukuqina kwempembelelo yobushushu obuphantsi, kodwa kuya kuphulukana namandla athile, kwaye amandla okuqina aphantsi ngokubanzi 500MPa; I-GER-N27L (W707) Ukongeza kwiinqaba, iphinda isetyenziswe kwi-09MnNiDR i-steel ethylene spherical tanks, ngelixa i-GER-N27 (W707Ni) isoloko isetyenziselwa izikhongozeli zokushisa eziphantsi ezifuna kuphela unyango lwe-annealing heat. Oku kulandelayo kuya kunika imizekelo yesicelo kunye nokusebenza okuhambelanayo kwe-GER-N27L kunye ne-GER-N27.
