2. Tsarin sanyaya & Kula da thermal

Aluminum tabo walda yana sanya maɗaukakin zafi sosai akan na'urorin lantarki.

• Na'urorin sanyaya ruwa{0}masu sanyaya dole ne.
• Adadin kwararar ruwa na musamman:0.5-1.5 gal/min (2-6 L/min).
• Kula da zafin ruwa da matsa lamba don kiyaye zafin wutar lantarki.
• A cikin yanayin sanyi, tabbatarkariyar daskare -da magudanar ruwa mai kyau don gujewa lalacewa.

Ingantacciyar tsarin sanyaya da cika fuska yana tsawaita rayuwar lantarki kuma yana inganta daidaiton walda.

Babban ingancin walda tabo na aluminum ya dogara ba kawai ga kayan aiki da suka dace ba har ma da madaidaicin sarrafa siga.

Mahimman sigogi sun haɗa da:

• Welding Current

1. Aluminum yana buƙatar mafi girma halin yanzu fiye da karfe.
2. Don ~ 1.2 mm takardar aluminum, shawarwari na yau da kullun sun isa:22,000-28,000 A (22-28 kA).

• Ƙarfin Electrode

1. Dole ne a tabbatar da daidaiton lamba da matse iska/oxide yadudduka ba tare da nakasu bangaren ba.
2. Ƙarfin da ya dace ya bambanta ta hanyar kauri da lissafi kuma dole ne a daidaita shi{0}}.

• Lokacin walda

1. Amfanigajeren lokacin waldasaboda saurin gushewar zafi na aluminum.
2. Yawanci kawai dubun millise seconds (ms) ko ƴan hawan keke.

• Lokacin Matsi & Lokacin Riƙe

1. Lokacin Matsi: clamps sassa kafin halin yanzu gudana, taimaka karya oxide fim.
2. Rike Lokaci: yana kula da matsa lamba bayan tsayawa na yanzu har sai nugget ya ƙarfafa, yana tabbatar da ƙarfin walda.

• Multi{0}}pulse / Multi{1}} Welding

1. Don kauri, hadaddun, ko babba -taurin mutuwa-simintin aluminum, tsarin tsari da yawa- (pre{3}} zafi → babban weld → ƙirƙira) yana haɓaka ingancin ƙugiya kuma yana rage lahani.

Ana ba da shawarar sosai don kafa atsarin waldaga kowane abu, kauri, da saitin kayan aiki.

Don walƙiya juriya ta aluminum, ma'aunin masana'antu shine:TS EN ISO 18595: 2021 - Juriya ta wurin Welding na Aluminum da Aluminum Alloys

Ana amfani da takardar aluminum 0.6-6 mm, extrusions, da simintin gyare-gyare (ciki har da mutu{2}} simintin aluminum).

Mabuɗin mahimmanci:

• Yana ba da shawarar lantarki gami da jan ƙarfe kamar ISO 5182 Class A2/2.
• Ya shafi masu walda benci, bindigogin walda, tsarin mutum-mutumi, da tsarin tabo da yawa.
• Yana ƙayyade hanyoyin gwaji don girman ƙugiya, ƙarfi, da ingancin walda.
• Yin amfani da kayan aikin ISO{0} yana ba da sauƙi don cimma daidaiton samarwa da biyan buƙatun QC.

1. Kula da Electrode

Saboda aluminum yana gurɓata kuma yana lalata na'urorin lantarki da sauri, sutura ko sake fasalin dole ne ya faru a ƙayyadaddun tazara (misali, kowane welds 500-1,000).

2. Kula da Tsarin Sanyaya

Saka idanu:

• Yawan kwarara
• Yanayin zafin ruwa
• Ruwan matsa lamba
• Hana zafi fiye da kima, haɓaka sikeli, ko daskarewa lalacewa.

3. Tsaro & Kula da Muhalli

• Yi amfani da haƙar hayaki mai kyau don ƙarfe oxides.
• Tabbatar da ingantaccen ƙasan wutar lantarki da kwanciyar hankali na lokaci uku{0}.
• Guji sauyin wutar lantarki, wanda ke shafar daidaiton walda.

4. Quality Records & Traceability

• Alamar walda
• Kula da Electrode
• Matsayin tsarin sanyaya
• Sakamakon gwajin weld (jinkirin, bawo, ko gwaji mai lalacewa)

Wannan yana da mahimmanci don samar da barga mai yawa.

5. Shawarwari Na Musamman na Fasaha (Nazari)

Kammalawa

Spot walda mutu -simintin aluminum ya fi rikitarwa fiye da karfen walda. Nasarar tana buƙatar:

• Na'urorin lantarki na musamman
• Tsarin ruwa mai ƙarfi{0}} sanyaya da kulawa
• Madaidaicin sarrafa siga
• Daidaita daidai da ISO 18595
• Gudanar da inganci mai ci gaba

Ta hanyar haɗa kayan aiki masu dacewa, sarrafa tsari, da kulawa kawai za su iya samun ƙarfi, maimaituwar walda akan mutu -simintin aluminum, musamman a manyan masana'antun da ake buƙata{1} kamar na motoci da na lantarki.
