Mpɛn pii no, anyɛ yiye koraa no, nkwaa biara hwehwɛ sɛ wɔde wɔn nsa ka 2 na ama wɔahu gyinabea a ɛda hɔ ne nea ɛkɔ soro no. Robɔt no bɛka saa search vectors yi ho na ayɛ triangulate gyinabea a welded joint no wɔ.
Wɔ ntwea so anaa akyi ano nkwaa no, mpɛn pii no, nea ɛto so abiɛsa a wɔde ka ho fi robɔt no mu no ho hia na ama wɔanya gyinabea a ɛfata nyinaa na ama robɔt no ahu na 'track' nkwaa no.
Touch sensing ho wɔ mfaso kɛse sɛ joint tracking solution a ne bo nyɛ den. Eyi yɛ ano aduru a ɛyɛ mmerɛw a egyina softwea so a wubetumi de adi dwuma afi Teach Pendant no mu a wunni nhyehyɛe foforo.

Nanso, Touch Sensing wɔ anohyeto ahorow bi, na ɛma ɛyɛ ano aduru a etu mpɔn yiye ma nkwaa a ɛyɛ mmerɛw ne seam tracking. Nea edi kan ne sɛ touch sensing yɛ adeyɛ a ɛyɛ brɛoo, a search vector biara kɔ soro simma 3 kosi 5. Enti, sɛ wowɔ touch-sensing wɔ 2D fã bi so a, wubetumi de 6 kosi 10 seconds aka welding cycle no ho, na sɛ wo de touch-sensing a 3D part a, cycle time ma arc biara mfiase no kɔ soro seconds 15.
Mfomso dodow a ɛwɔ touch sensing wɔ arc awiei no nso yɛ kɛse koraa sen ano aduru afoforo. Nkotow nhama anaa nneɛma a ɛho ntew na ɛyɛ mmerɛw ma ɛyɛ den sɛ wobɛyɛ biribi a ɛma wote nka bere nyinaa.

Touch sensing nso yɛ anohyeto esiane solder joints no su nti. Fillet ne lap nkwaa ne nkwaa a wɔtaa kamfo kyerɛ, nanso wɔ lap nkwaa mpo ho no, ɛsɛ sɛ wosusuw nneɛma no mu duru ho.

2. Ɛnam arc seam tracking so .
Ɛnam Arc Seam Tracking (Tast) so no yɛ wo dwumadie a ɛfa touch sensing ho no fã a ɛtɔ so mmienu. Sɛ woka touch sensing akyi a, wubehu arc mfiase ne arc awiei, na afei wode 'through arc seam tracking' adi dwuma. Tast tumi di z-axis ne y-axis a ɛwɔ nkwaa no mu akyi, a ɛfata yiye ma nneɛma a ɛyɛ den.
Tast hwehwɛ sɛ wɔyɛ nwene ho nhyehyɛe. Sɛ waya no dannan fi nkwaa no fã biako kɔ ɔfã foforo a, voltage no resakra. Eyi te saa efisɛ waya no ntrɛwmu so tew bere a ano no sesa kɔ adwumayɛ kwan no so no. Eyi ma robɔt no tumi kyerɛ voltage nsakrae ase na ɔyɛ nsakrae wɔ ɔkyerɛkyerɛ kwan no mu ma ɛkɔ so yɛ welding gyinabea a ɛfata wɔ nkwaa no mu.
Tast fata ma nneɛma a ɛyɛ den lap joints, a ɛsɛ sɛ ɛyɛ 5 mm (1/4 inch) anaasɛ ɛyɛ den na ama atumi agyina. Ɛnyɛ nea wɔkamfo kyerɛ sɛ wobɛyɛ tast wɔ ne kɛse a ɛba fam mu (nokwarem no, minhuu no da sɛ mede seam tracking app bedi dwuma wɔ me mfe a mede ayɛ adwuma no mu), anyɛ saa a wubetumi de wo ho ato asiane mu sɛ wobɛdi nwansena akyi anaasɛ woakyeakyea welding-eyi bɛtew weld no mudi mu kura so wɔ adeyɛ no nyinaa mu.
Nea enti a wɔkamfo kyerɛ sɛ wɔmfa nneɛma a ɛyɛ tratraa nni dwuma wɔ welding no nyinaa mu, na ɛtaa hohoro anaa ɛyi mprɛte a ɛwɔ soro no mmati. Saa ahotew yi mma voltage nsakrae kɛse ba, a ɛma robɔt no hwehwɛ-eyi ne baabi a nwansena ho asiane no ba.
Anohyeto foforo a ɛwɔ TAST mu ne sɛ ɛsɛ sɛ woma bere a wɔde di kyinhyia no yɛ kɛse efisɛ ɛhwehwɛ sɛ robɔt no fa nkwaa no mu. Mpɛn pii no, Tast akwantu ahoɔhare no anohyeto yɛ nsateakwaa 35-50 wɔ simma biako mu. TAST nso yɛ MiG applications-TIG anaa plasma nko ara na ɛrentumi nyɛ yiye.
Awiei koraa no, TATST yɛ carbon dade anaa dade a ɛnyɛ den nkutoo. Voltage no ne aluminum nhyia, na TAST ntumi nyɛ adwuma no yiye. Tebea a ade no wom nso ho hia yiye. Ɔfã ahotew, nsusuwii anaasɛ rust wɔ nkɛntɛnso wɔ parameter kuw no so efisɛ wode gyinapɛn a ɛho hia ma voltage nsakrae no si hɔ. Enti, 2% voltage nsakrae wɔ negative y so esiane oxide scale anaa rust a ɛwɔ metal no so nti, ɛbɛma TAS no su a ɛne ne ho nhyia no aba.
Esiane sɛ ɛsɛ sɛ wɔde weld di dwuma de di robɔt no akyi nti, Tast nso ntumi nyɛ adwuma a ɛyɛ dry. Stickiness nso yɛ ɔhaw, efisɛ sɛ wotwam tack no a, sticking out no bɛsesa, enti robɔt no bɛhwere kwan kosi sɛ ebepue wɔ tack weld no fã foforo.
3. 2D anisoadehu nhyehyɛe .
Fa no sɛ 2D anisoadehu te sɛ mfoninitwa afiri. Egye ɔfã a eye sen biara no ho mfonini ansa na abɔ arc no na ɛne mfonini no ne ɔfã foforo biara a edi hɔ a ɛhwehwɛ offset biara a edi hɔ no hyia na ɛsesa welding kwan no. Ɛma wonya mfonini tuntum ne fitaa nkutoo, baabi a mfonini no wɔ ne soro. 2D ntumi nkyerɛ ɔsorokɔ anaa emu dɔ, na wommu no sɛ ɛyɛ adeyɛ a wotumi de ho to so ma seam tracking.
Nkwaa te sɛ V-joints ne lap nkwaa yɛ ɔhaw kɛse ma 2D anisoadehu efisɛ entumi nhu sɛnea welded nkwaa ahorow yi mu dɔ. Nneɛma a ɛhyerɛn te sɛ aluminium nso yɛ ɔhaw ma 2D nhyehyɛe ahorow. Mpɛn pii no, wɔde 2D di dwuma de kyerɛ afã horow sen sɛ wɔde bedi akyi. Ɛyɛ nhyehyɛe a egyina anisoadehu so, enti akyi hann a ɛtwetwe adwene no ho hia kɛse ma optical components no adwumayɛ. Nea ɛka ho no, camera lens no yɛ sensitive paa wɔ welding spatter ne arc damage ho.
