1. Ahosiesie ansa na welding .
Pre-welding ahosiesie ma titanium alloy welding ho hia yiye, titiriw no, nea ɛka ho ne:
(1) Nneɛma a wɔde hohoro nneɛma ho ansa na welding .
Ansa na welding no, ɛsɛ sɛ wɔyɛ titanium aduru no ani wɔ 50mm a ɛwɔ strip no afã abien no nyinaa mu no ho yiye kosi sɛ ade no ankasa dade a ɛhyerɛn no bɛda adi. Sɛ wo ho yɛ fɛ wie a, fa ntama fitaa a ɛho tew a wɔde sirikyi ayɛ ne acetone popa nkataso no ano na ama woayi oxide film, srade, nsu, mfutuma ne efĩ afoforo afi welding beae no koraa. Nanso wɔ nneɛma a wɔyɛ a ɛwɔ automation a ɛkorɔn ho no, saa kwan yi nyɛ nea mfaso wɔ so. Enti, wobetumi de deburring afiri ahyɛ mu ansa na wɔayɛ welding fã no.
(2) Nneɛma a wɔde yɛ debugging .
Ansa na welding no, hwɛ sɛnea gas cylinder biara nhyɛso te yiye na ama woahwɛ ahu sɛ mframa biara nhyɛso no dɔɔso. Siesie na hwɛ afiri a wɔde yɛ afiri a ɛma nsu fi paipu so a ɛyɛ adwuma ankasa . sɛnea ahoɔden a wɔde ma ne wire feeder no reyɛ adwuma yiye. Wɔ nsakrae ne nhwehwɛmu mu no, mpɛn pii no wobetumi de welding torch no ahyɛ welding seam no tenten nyinaa so de ahwɛ sɛ nnwinnade no reyɛ adwuma yiye na welding torch no ne welding seam no ayɛ pɛpɛɛpɛ. Wɔkamfo kyerɛ sɛ wɔmfa Visual Weld Tracking Device nhyɛ welding gun adwumayɛbea no mu, a ebetumi ahwɛ weld a ɛne ne ho hyia no so yiye. Bere a offset no aba akyi no, wɔteɛteɛ weld track no ara kwa.
(3) Nneɛma a wɔde yɛ welding .
Sɛ wode plasma arc welding (Paw) di dwuma a, ion gas, nozzle shielding gas, support cover ne back shielding gas no de argon a ɛyɛ pure a edi kan (≥99.99%) di dwuma;
Wɔde laser welding (LW) di dwuma, mframa a ɛbɔ wɔ nkyɛn no yɛ helium a ɛho tew (≥99.99%), na drag hood ne akyi ahobammɔ mframa no yɛ argon a ɛho tew a ɛyɛ grade a edi kan (≥99.99%);
2 . Welding kwan no .
(1) Plasma arc welding .
Wɔ titanium mprɛte a ne kɛse yɛ 2.5 ne 15mm ntam no, sɛ groove no yɛ I-nsusuwii a, wobetumi de tokuru ketewa kwan no adi dwuma de ayɛ weld wɔ bere koro mu. Sɛnea ɛbɛyɛ a tokuru ketewa no bɛkɔ so agyina no, groove a mframa ahyɛ mu ma a ɛwɔ akyi no kɛse yɛ 30mm × 30mm. Paw wɔ process parameters pii. Sɛ wɔde tokuru ketewa kwan no di dwuma a, nea ɛfa nozzle diameter, welding current, ion gas a ɛsen, welding ahoɔhare, shielding gas flow, ne nea ɛkeka ho titiriw.
(2) Laser a wɔde yɛ welding .
Nneɛma titiriw a wɔde yɛ laser welding no bi ne laser ahoɔden, welding ahoɔhare, defocusing dodow, afã a ɛbɔ gas sen ne shielding gas flow rate. Esiane sɛ laser welding no ahoɔhare a ɛkorɔn yiye nti, mpɛn pii no ɛrentumi nyɛ yiye sɛ wɔbɛsesa adeyɛ no parameters wɔ welding nhyehyɛe no mu. Enti, ɛho hia sɛ wohu parameters a wɔaka abom a eye sen biara denam pre-tests so ansa na wɔayɛ formal welding no, na interlayer no hyew wɔ welding bere mu no nsen 100°C. Saa bere yi, standard production process recipe no ho hia yiye. Hangao Tech (seko mfiri) a ɛyɛ pɛpɛɛpɛ a ɛyɛ pɛpɛɛpɛ Titanium aduru . Steel Tube Production Line Pipe Manufacturing Machine ne PLC Intelligent System yɛ adwuma, betumi akyerɛw na akora so wɔ nsɛm a wɔde yɛ adwuma no nyinaa mu wɔ bere ankasa mu.
(3) Laser-mig a wɔde afrafra a wɔde yɛ welding .
Sɛ woregye LW-MIG hybrid welding atom a, ɔhyew fibea abien na ɛwɔ hɔ, laser ne arc, na ɔhyew fibea biara wɔ process parameters pii a ɛsɛ sɛ wɔyɛ nsakrae. Enti, sɔhwɛ pii ho hia na ama laser ne arc no ahyia wɔ ɔkwan a ɛne ne ho hyia so. Ɛsɛ sɛ wɔyɛ nsakrae wɔ laser ne arc no gyinabea a ɛfa ho no mu sɛnea ɛfata bere a wɔreyɛ welding no.
3. Nhwehwɛmu a wɔyɛ wɔ welding akyi .
Sɛ welding no wie a, wɔhwɛ sɛnea weld no te na wɔyɛ sɔhwɛ a ɛnyɛ nea ɛsɛe ade. Saa bere yi, wobetumi de eddy current sintɔ afiri bi aka ho. Sɛ wohu sɛ weld no nyɛ papa anaasɛ ɛwɔ mu a, afiri no bɛbɔ gyegyeegye na alarm. Titanium aduru no kɔla a ɛyɛ fɛ no betumi akyerɛ sɛnea weld no ho agu fĩ akodu. Sɛ yɛbɛka no ɔkwan biara so a, dwetɛ fitaa kyerɛ ahobammɔ a ɛkyɛn so, na ɛkame ayɛ sɛ mframa a wɔsɛe no a ɛyɛ hu biara nni hɔ; Weld kɔkɔɔ a ɛyɛ kɔkɔɔ ne sika kɔkɔɔ a ɛyɛ sika kɔkɔɔ no nni nkɛntɛnso kɛse biara wɔ mfiridwuma mu nneɛma so; Kɔla afoforo te sɛ bruu ne fitaa nyɛ nea ɛyɛ papa na wontumi nnye ntom. Bere tenten a ahobammɔ a ɛwɔ beae a ɛhɔ yɛ hyew kɛse no fata no, sɛnea welding no te wɔ welding akyi no yɛ fitaa a ɛyɛ fitaa anaa sika kɔkɔɔ titiriw. Nanso, esiane sɛ wontumi mfa drag cover no nhyɛ arc starting section no mu koraa nti, protection effect a ɛwɔ arc starting no mu no yɛ bɔne kakra. Wɔ tebea horow a ɛfata mu no, akyi a ɛda adi no welding mfiri nhyehyɛe no ayɛ yiye, na sintɔ biara nni hɔ te sɛ mpaapaemu, fusion a enni hɔ, pores, weld bumps, ne nea ɛkeka ho.
