Wɔ laser welding mu no, ɔkwan bɛn na yɛbɛfa so abɔ, ɔkwan bɛn so na yebetumi apaw nnyinasosɛm a ɛfa mframa ho?
1) Ɔkwan a wɔfa so bɔ .
Mprempren akwan titiriw abien na ɛwɔ hɔ a wɔfa so bɔ mframa a ɛbɔ ho ban: biako yɛ paraxial afã a ɛbɔ ahobammɔ, sɛnea wɔada no adi wɔ Mfonini 1 mu no; Ɔfoforo no yɛ coaxial protective gas, sɛnea wɔakyerɛ wɔ Mfonini 2 no mu no.
Sɛnea wɔpaw akwan abien a wɔfa so bɔ no yɛ nneɛma pii a wosusuw ho yiye. Mpɛn pii no, wɔkamfo kyerɛ sɛ wɔmfa ɔkwan a wɔfa so bɔ mframa a ɛbɔ ho ban no di dwuma.
2) Nnyinasosɛm a ɛfa ɔkwan a wɔfa so bɔ ho .
Nea edi kan koraa no, ɛsɛ sɛ ɛda adi pefee sɛ nea wɔfrɛ no 'oxidation' a ɛwɔ weld no mu no yɛ din a wɔtaa de di dwuma kɛkɛ. Wɔ nsusuwii mu no, ɛkyerɛ sɛ nnuru a ɛwɔ weld no ne nneɛma a epira wɔ mframa no mu no ma weld no su sɛe. Ɛne oxygen, nitrogen ne hydrogen a ɛwɔ mframa mu no yɛ adwuma wɔ nnuru mu.
Sɛnea ɛbɛyɛ a weld no rensi 'oxidized' no yɛ sɛ wobɛtew anaasɛ wobɛkwati sɛ contact a ɛte saa a epira no ne weld dade no wɔ ɔhyew a ɛkorɔn mu. Ɔtare no mu dade no yɛ den na ne hyew kɔ fam sen ɔhyew pɔtee bi wɔ bere no nyinaa mu.
Asɛm no mu nhwehwɛmu .
Sɛ nhwɛso no, titanium a wɔde ayɛ welding no tumi twe hydrogen ntɛmntɛm bere a ɔhyew no boro 300°C no, ɛtwe oxygen ntɛmntɛm bere a ɛboro 450°C no, na ɛtwe nitrogen ntɛmntɛm bere a ɛboro 600°C no, enti titanium aduru a wɔde ayɛ weld no yɛ nea ɛyɛ den na ɔhyew no kɔ fam na ɛho hia sɛ wɔbɔ ho ban yiye sen sɛ wɔbɛbɔ ho ban, sɛ wɔbɛyɛ saa a, wɔbɛbɔ ho ban yiye.
Ɛnyɛ den sɛ yɛbɛte aseɛ afiri atifi hɔ nkyerɛkyerɛmu no mu sɛ ɛnyɛ sɛ ɛhia sɛ mframa a ɛbɔ ho ban no bɔ weld pool no ho ban wɔ berɛ a ɛfata mu nko, na mmom ɛhia sɛ ɛbɔ beaeɛ a wɔayɛ no weld na ɛyɛ den ara kwa no ho ban, enti paraxial side a wɔakyerɛ wɔ Mfonini 1 mu no, wɔtaa de di dwuma wɔ blow shielding gas, ɛfiri sɛ ahobanbɔ kwan a ɛwɔ saa kwan yi so no trɛw sene sɛ yɛde yɛn ho bɛbɔ coaxial protection kwan no ara ho, titiriw no, yɛn deɛ, titiriw no, yɛde yɛn ho abɔ ho.
Wɔ mfiridwuma mu dwumadie ho no, ɛnyɛ nneɛma nyinaa na ɛtumi de mframa a ɛbɔ ho ban a ɛwɔ afã-asen no di dwuma. Wɔ nneɛma pɔtee bi ho no, coaxial protective gas nkutoo na wobetumi de adi dwuma.

1) Ntrɛwmu a ɛyɛ tẽẽ weld .
Sɛ weld seam shape a ɛwɔ product no mu no yɛ tẽẽ a, joint form no betumi ayɛ butt joint, lap joint, female angle joint anaa lap joint. Wɔ saa ade yi ho no, eye sɛ wode shielding gas kwan a ɛwɔ side-axis side blowing bedi dwuma.
2) Plane closed graphic welds .
Sɛ weld seam no nsusuwii yɛ ade a wɔato mu te sɛ plane no ntwemu, plane polygon, plane multi-segment line, ne nea ɛkeka ho a, joint form no betumi ayɛ butt joints, lap joints, lap joints, ne nea ɛkeka ho, na nneɛma a ɛwɔ saa su yi nyinaa de coaxial shielding gas di dwuma. Ɔkwan no ye sen saa.
