Mi tingim yet namba wan taim mi lukim wanpela bikpela 51-inch maining rim i bruk i go daun stret long namel. Em i wanpela moning we i no gat planti hevi long en long dispela hap. Trak i pulap long trak, weta i hat tru, na mipela i kisim liklik mani long delei. Long ol yia mi bin wok wantaim ol hevi-diuti operesen, mi painim olsem 'premature breaking' long ol 'wheel hubs' em i wanpela hevi we i save givim bikpela hevi long ol sait menesa. Mipela i ting ol dispela bikpela ain straksa bai stap oltaim. Ol i luk olsem ol i no inap bagarap. Tasol trupela samting i stori long narapela kain stori.
Planti taim mi save kisim ol askim long ol enjinia bilong sait we i save askim mi long wanem as ol rim bilong ol i bagarap planti mun pastaim long taim bilong stretim. Ol i laikim ol bekim. Mi kliagut tru long belhat. Taim yu ranim wanpela 100-ton damp trak, yu nidim ol komponen we i wok gut tru. Yu no inap baim ol saprais. Nau, mi laik serim ekspiriens bilong mi yet long dispela bikpela het pen na tok klia long wanem samting i rong aninit long peint.
Painimaut as bilong ol bruk
Planti manmeri i save soim pinga long ol draiva bilong trak pastaim. Ol i ting olsem pasin bilong draivim ka nogut i save kamapim hevi. Maski pasin bilong draivim ka i bikpela samting, as bilong dispela hevi i save kamap long gutpela bilong ain na wok bilong weldim. Mi save lusim planti aua long lukluk long ol komponen we i no wok gut, na ol bruk i save stat long ol 'weld seams' o 'bead seat band'.
Taim yumi toktok long wanpelagutpelarim straksa, yumi no inap dipen long ol filings. Yumi mas lukluk long ol hatpela data. Olsem, wanpela 'rim' we ol i wokim long 'standard Q235 steel' bai i no inap long karim hevi bilong 80 ton long wanpela 'haul road'. Long kamapim gutpela straksel stebiliti, yu mas i gat bikpela strong na liklik-aloi straksel steel. Folem ol samting we mi save yusim long olgeta de, mipela i nidim Q345B o Q460C-greid ain bilong ol hevi maining aplikesen. Q460C i givim strong bilong 460 MPa. Sapos ol 'rims' bilong yu nau i no yusim planti samting, orait yu draiv long taim yu kisim dinau long en.
Denja i stap hait insait long ol weld
Antap long ain yet, wok bilong weldim i haitim planti tok hait. Mi save tokim tim bilong mi olsem wanpela 'rim' i strong olsem 'weld' bilong en we i no strong tumas. Manual welding i save lusim planti spes long ol man i ken popaia. Wanpela opereta we i les pinis em i ken lusim ol liklik 'air pocket' insait long 'weld seam'. Aninit long bikpela presa, ol dispela liklik poket i save tanim i kamap ol liklik -mak. Ol dispela liklik bruk i save gro long olgeta wan wan de inap long olgeta rim i bagarap.
Sapos yu laikim wanpelai wankainlaip bilong prodak, faktori i mas yusim Submerged Arc Welding (SAW). Dispela otomatik proses i mekim na i go insait tru na i no gat wanpela 'air pocket' i stap. Mi save sekim gut ol dispela samting long wok bilong mi long olgeta de. Ultrasonic non-destructive testing (NDT) i no ken soim wanpela bagarap long 15mm dip. Sapos yu abrusim dispela verifikasen, yu putim olgeta samting long hevi.
Mekim stretpela disisen bilong fleet bilong yu
Mi save olsem maket i save pulapim yu wantaim ol narapela samting we i no gat bikpela pe. Mi lukim ol prais tag, na mi tok ol i luk naispela. Tasol, sapos yu no tromoi bikpela mani long baim wanpela 'rim' tude, dispela i mekim na tumora bai yu tromoi bikpela mani moa long 'downtime'. Mi strongim yu long sekim ol teknikel data na ol ditel bilong prodak longhttps://www.aqrim.comtaim yu skelim neks samting yu baim. Ol i givim ol stretpela samting yu nidim long mekim gutpela disisen.
Long mekim ol samting i kamap klia, mi wokim wanpela kwik refrens tebol aninit. Mi save yusim dispela stretpela 'checklist' taim mi wok long sekim ol nupela wil komponen bilong wok bilong mipela.
