1. Weld kɛse no ntumi nni ahwehwɛde ahorow no ho dwuma .
Weld kɛseɛ ntumi nhyia ahwehwɛdeɛ no titire kyerɛ weld reinforcement ne reinforcement nsonsonoeɛ, weld trɛw ne ne tɛtrɛtɛ nsonsonoeɛ, misalignment, post-weld deformation ne nsusuiɛ foforɔ a ɛnni gyinapɛn no so, weld sorokɔ a ɛnyɛ pɛpɛɛpɛ, ne tɛtrɛtɛ a ɛnyɛ pɛpɛɛpɛ, ne deformation kɛseɛ twɛn. Ɛnyɛ sɛ weld no trɛw a ɛnhyia no bɛma weld no a ɛda adi no ayɛ nea ɛnyɛ fɛ nko, na mmom ɛbɛka ahoɔden a ɛwɔ weld ne dade a ɛwɔ ase no ntam no nso; Sɛ weld reinforcement no sõ dodo a, ɛbɛma stress concentration, na sɛ weld no sua sen base metal a, ɛrennya reinforcement a ɛdɔɔso. nkwaa ahoɔden; Ɔfã a ɛnteɛ ne deformation a ɛboro so no bɛkyinkyim ahoɔden a ɛde kɔ nipadua no mu no na ɛde adwennwen a ɛwɔ mu no aba, na ɛma ahoɔden so tew.
Nea ɛde ba: Bevel angle anaa blunt edge a ɛmfata ne stainless steel welded paipu a ɛnnyɛ pɛpɛɛpɛ; welding process parameters a wɔpaw a ntease nnim; Welder adwumayɛ ho nimdeɛ a ɛba fam, ne nea ɛkeka ho.
Nneɛma a wɔde siw ano: Paw groove angle ne assembly clearance a ɛfata; ma nhyiam no su tu mpɔn; Paw welding nhyehyɛe no mu nsɛm a ɛfata; Ma welder no adwumayɛ ho nimdeɛ gyinabea nyɛ yiye, ne nea ɛkeka ho.
2. Wɔatwitwa so .
Esiane sɛ wɔpaw welding nhyehyɛe no mu nsɛm a ɛnteɛ anaasɛ ɛnyɛ adwuma yiye nti, wɔfrɛ groove anaa adwenemhaw a ɛnam dade a ɛwɔ ase no so a ɛwɔ weld toe no so no yɛ no ase. Ɛnyɛ sɛ undercut no ma ahoɔden a ɛwɔ welded joint a ɛwɔ welded pipe no mu no yɛ mmerɛw nko, na mmom ɛyɛ mmerɛw sɛ ɛde mpaapaemu ba esiane adwennwen dodow nti.
Nea ɛde ba: Titiriw esiane sɛ current no sõ dodo nti, arc no ware dodo, electrode no anim no nyɛ nokware, na ɔkwan a wɔfa so de electrode no kɔ no nyɛ nea ɛfata.
Nneɛma a wɔde siw ano: Paw welding current a ɛfata ne welding ahoɔhare bere a welding ne electrode arc welding.
Sɛ yɛbɛka no ɔkwan biara so a, dodow a welding ahoɔhare no yɛ ntɛmntɛm no, dodow no ara na arc no bɛtwe akɔ anim. So ɔkwan bi wɔ hɔ a wobɛfa so ahwɛ ahu sɛ arc tenten a ɛyɛ daa no na wobɛhwɛ sɛ ɛyɛ adwuma yiye a worenkɔ fam? Hangao Tech betumi aboa wo. Yɛn ho a ɛyɛ yɛn ho nkɔso .

Ɛnka welding no su, na mmom ɛhwɛ nso sɛ ɛyɛ adwuma yiye.
3. Ɛnyɛ nea ɛkɔ mu .
Ntini a enni mũ kyerɛ adeyɛ a ɛne sɛ ntini a ɛwɔ welded joint no mu no ntumi nkɔ mu koraa bere a wɔde dade a ɛnyɛ den a wɔde weld ayɛ no weld no. Sɛ ɛkɔ mu a, ɛbɛma adwennwen no ayɛ kɛse na ɛnyɛ den sɛ ɛbɛma mpaapaemu aba. Wɔmma kwan mma wɔmfa welded nkwaa a ɛho hia no nkɔ mu koraa.
Nea ɛde ba: Groove angle anaa gap no sua dodo, blunt edge no sõ dodo, na nhyiam no nyɛ papa; Welding process parameters no yɛ nea wɔpaw no yiye, welding current no sua dodo, welding ahoɔhare no yɛ ntɛmntɛm dodo; Welder no adwumayɛ ho ɔkwan no nyɛ papa, ne nea ɛkeka ho.

4. Ɛnyɛ fused koraa .
Fusion a enni mũ kyerɛ sɛnea nsu a ɛwɔ weld bead no ne dade a ɛwɔ ase no ntam no nnɔɔso na ɛne no bɔ anaasɛ weld bead ne weld bead ntam bere a wɔreyɛ fusion welding no. Fusion a enni hɔ no ma nkwaa no mfiri su so tew tẽẽ, na fusion a enni hɔ kɛse no bɛma welded structure no antumi anso koraa.
Nea ɛde ba: Titiriw esiane ahoɔhare kɛse ne welding current a ɛba fam bere a welding stainless steel welded pipes nti, welding heat input no sua dodo; Welding poma no yɛ eccentric, anim a ɛda welding poma ne weldment no ntam no nyɛ nea ɛfata, na arc pointing no dan kɔ; Nsõ ne efĩ wɔ groove no afã fasu no so, na slag a ɛho tew a enni mũ wɔ ntoatoaso ntam.
Nneɛma a wɔde siw ano: Paw welding nhyehyɛe parameters yiye, yɛ adwuma yiye, hyɛ interlayer ahotew mu den, na ma welder adwumayɛ ho nimdeɛ, ne nea ɛkeka ho no tu mpɔn.
5. Welding akisikuru .
Weld lump kyerɛ dadeɛ akuru a ɛnam dadeɛ a ayow a ɛsen kɔ dadeɛ a ɛwɔ nnyinasoɔ a ɛnnɔɔso a ɛwɔ weld no akyi wɔ welding dwumadie no mu no na ɛyɛeɛ. Ɛnyɛ sɛ weld bead no nya weld seam a ɛwɔ stainless steel welded paipu no so nko, na mmom ɛtaa nso wɔ slag inclusions ne enterfiration a enni mũ wɔ weld bead no.
Nea ɛde ba: Blunt edge no sua dodo na ntini no mu nsonsonoe no sõ dodo; Welding current no yɛ kɛse na welding ahoɔhare no yɛ ntɛmntɛm; Welder no adwumayɛ ho nimdeɛ gyinabea no sua, ne nea ɛkeka ho.
Nneɛma a wɔde siw ano: Paw welding process parameters a ɛfata sɛnea welding gyinabea ahorow te, di fusion tokuru no kɛse so pɛpɛɛpɛ, na ma welder no adwumayɛ mfiridwuma gyinabea no nyɛ yiye, ne nea ɛkeka ho.
Sɛ yegyina yɛn suahu so a, anyɛ yiye koraa no, nneɛma 10 na ɛwɔ hɔ. Ɛnnɛ yɛwɔ hwɛ 5 a edi kan no. Yɛsrɛ sɛ di yɛn wɛbsaet no akyi na woanya update.
