Tok i go pas
Insait long wok bilong prosesim na wokim ol metal, ol i save yusim planti samting we i gat 'zinc-koting long en bikos ol i no inap bagarap na ol i luk nais long bilasim. Tasol, taim ol i mas weldim ol dispela samting long yusim 'medium'ol masin bilong weldim ol samting, bikpela bilong 'zinc coating' i save kamap wanpela bikpela samting we i save mekim wok bilong weldim i hat. Dispela atikol i toktok long askim: "Wanpela 'zinc coating' we i tik moa inap long weldim wantaim 'medium'ol masin bilong weldim ol samtingmoa salens?" na i givim ol gutpela rot bilong stretim ol dispela salens.
Hevi bilong 'Zinc Coating Thickness' long hevi bilong weldim
Namba wan wok bilong 'zinc coating' em long lukautim 'base metal' long 'corrosion', tasol sapos em i stap, dispela i mekim wok bilong weldim i hat. Moa yet, wanpela tikpela 'zinc coating' i save mekim ol salens bilong weldim i go antap. Namba wan, 'zinc layer' i gat bikpela 'electrical resistance', na dispela i mekim na 'contact resistance' i go antap long taim bilong 'welding' na i gat bikpela 'localized resistance' long 'weld point', we i save bagarapim kwaliti na strong bilong 'weld'. Namba tu, gutpela 'thermal conductivity' bilong 'zinc' i save mekim hat i lus hariap long taim bilong weldim, na i nidim bikpela wok bilong weldim o longpela taim bilong weldim long kisim gutpela risal. Na tu, wok bilong weldim samting inap kamapim ol nogut ges na smok long 'zinc coating', na dispela inap long kamapim hevi long ples wok na helt bilong opereta.
Ol rot bilong stretim hevi
Long stretim ol hevi bilong welding we i save kamap long ol tikpela 'zinc coating', tingim ol dispela rot:
Stretim ol samting bilong weldim:
- Gutpela wok bilong weldim karent, taim, na presa bihainim tiknes bilong 'zinc coating'. Long ol 'coating' we i tik moa, skruim 'current' na skruim taim bilong 'welding' long mekim inap hat na melting i kamap gut. Stretim presa bilong promotim gutpela 'fusion' bilong 'molten metal'.
Mekim gut wok bilong makim ol 'electrode':
- Yu mas makim ol samting bilong 'electrode' we i gat bikpela 'conductivity' na 'wear resistance'. Ol gutpela 'electrodes' i save daunim bagarap na lus bilong hat, na dispela i save helpim wok bilong weldim gut na i gat 'zinc-coated wokpis.
Mekim gutpela wok klinim:
- Klinim gut ol samting pastaim long yu weldim long rausim oil, ol 'oxide', na ol samting nogut. Ol i save yusim ol rot bilong grisim o klinim wantaim kemikal long ol tikpela 'zinc coating' bilong daunim 'contact resistance' na 'gas emissions'.
Mekim gutpela rot bilong pulim win:
- Strongim ol 'ventilation system' long rausim ol nogut ges na smok we i save kamap taim ol i weldim. Putim ol 'exhaust fan' o ol masin bilong klinim win long lukautim gutpela ples bilong wok.
Yusim ol helpim ikwipmen:
- Long ol wokpis we i gat ol tikpela 'zinc coating', tingim ol masin bilong hatim pastaim long apim tempereja bilong hap bilong weldim. O nogat, painim ol gutpela 'welding' teknoloji olsem 'laser welding' bilong kisim gutpela wok na gutpela wok.
Long pinisim, ol tikpela 'zinc coating' i save mekim wok bilong weldim i hat moa long 'medium'ol masin bilong weldim ol samting. Tasol, long rot bilong stretim ol paramita, makim ol stretpela 'electrodes', mekim klinpela ples, mekim gut 'ventilation', na yusim ol narapela ikwipmen, ol dispela salens inap long winim gut long kamapim ol gutpela 'weld'.
