Hau long makim ol robot bilong weldim ol samting long laser
Wanem Em Robot Laser Welding na Wok Prinsipel bilong en?
Robot laser weldingi bungim wanpela 'focused laser light source' wantaim ol 'programable industrial robots' o ol 'collaborative robots'. Em i senisim ol wok we ol i save holim long han wantaim ol gutpela na kontrolim mekanik muvmen long kamapim bikpela mak bilong ripit long ol wok bilong weldim.
Wanpela 'high-energy-density laser beam i save lukluk stret long join bilong ol wokpis, na i save meltim metal hariap tru na kamapim wanpela liklik 'molten pool'. Robot i save stiaim het bilong laser na i save muv long wankain spit. Ain we i melt i save go aut oltaim na bihain em i save kol hariap na kamap strong, na kamapim wanpela weld wantaim strongpela metalurgical bonding.
Ol bikpela samting: Laser i save givim bikpela eneji wantaim liklik hat tasol na liklik hap bilong hat-Affected Zone (HAZ), na dispela i save mekim ol wokpis i no save bagarap tumas. Em i gutpela long weldim ol liklik plet, ol gutpela hap na ol narapela kain metal.

Ultra-high Repeat Positioning Accuracy
Stretpela wok bilong putim 6-eksis indastrial robot i go inap long 0.02~0.05 mm. Long wokim planti tausen wokpis, weld posisen, penetresen dip na weld fomesen i stap wankain olgeta, na i rausim ol rong bilong wok long han na i daunim tru wok gen.
Liklik senis na gutpela kwaliti bilong pes
Taim hat i no go insait tumas, ol liklik plet i no soim klia 'warpage' bihain long ol i weldim. Ol 'weld' i liklik na gutpela, na dispela i mekim na ol i no inap mekim wok bilong 'grinding' o mekim isi tru, na dispela i daunim tru 'repair rate'.
Gutpela wok bilong prosesim samting i kamap gutpela moa
Long ol weld we i gat wankain longpela, spit bilong weldim bilong laser robotik welding sistem em 3 i go inap 8 taims bilong TIG welding na 2 i go inap 5 taims bilong MIG welding. Gutpela wok i kamap gutpela tru long ol longpela stretpela weld na ol standet hap we ol i wokim long bikpela hap. Impruvmen i sot long ol sotpela, kompleks na spesel-sep weld, olsem na yumi no ken ting olsem bai i gat 10-pela taim moa gutpela wok.
Wokman-sevim Otomatik Prodaksen
Nait-sif operesen we i no gat man i was long en i stap taim wok i pinis. Ol wokmanmeri i senis long wok bilong weldim long han na i go long wokim ol program, wokim ol tul na sekim ol ikwipmen, na dispela i daunim hevi bilong kisim ol profesenel welda.

Ol opereta i stap ausait long 'laser safety enclosure', na abrusim bagarap we i kamap long strongpela lait, bikpela -temperature spata, welding smok na 'zinc vapor exposure'.
Em inap long weldim ol spesel samting
Em i sapotim 'lap welding' bilong 'carbon steel', 'stainless steel', 'galvanized sheet', 'aluminium alloy', 'copper', 'titanium alloy' na ol narapela metal. Stebol weld fomesen i ken kamap long ol samting we i gat bikpela lait taim ol i putim wantaim ol hai-pawa laser jenereta.
Hau long makim wanpela Laser Welding Robot
Ol samting we i save pasim wok bilong makim ol samting: Laser Power → Robot Body Type → Auxiliary Accessories. Seleksen skop bilong narapela samting bai i go liklik bihain tasol long ol i konfemim paramita bilong bipo.
Step 1: Painimaut pawa bilong laser bihainim ol samting bilong wok na tikpela bilong plet
Tupela kain 'fiber laser' i stap: 'continuous-wave 'fiber laser' (gutpela long 'deep penetration welding' na ol 'thick plates') na 'pulsed fiber laser' (long ol 'ultra-thin precision components). Tebol aninit i stap olsem wanpela refrens bilong 'continuous-weve fiber laser seleksen. Pasin bilong weldim i save go insait tru long 'defocus', spit bilong weldim, 'wire feeding mode', kain 'shielding gas' na 'assembly gap'.
