Plastic arung arai ni hpe galaw shapraw ai hte gram lajang ai hta, plastic welding rods ni hpe hkrak jai lang ai gaw, weld n-gun hte ngut sai arai a hkrang hpe hkrak hkra hkra machyi shangun ai. Kaja ai welding ladat ni hpe sharin ya ai gaw bungli galaw ai atsam hpe shatsaw ya ai sha n-ga, arung arai sum ai lam hpe mung shayawm ya lu ai, n-gun jaw ai hte kam mai ai welding quality hpe mung hkam la lu ai.
Langai, base material hte bung ai welding rod hpe lata na matu ahkyak ai. Plastic amyu myu (PE, PP, hte PVC zawn re ai) ni hta grai shai ai heat-melting atsam ni nga ai, dai majaw htap htuk ai arung arai a welding rods ni hpe npawt nhpang arung arai amyu hpe madung tawn nna lata la ra ai. Ga shadawn, PE welding rod hpe polyethylene pipe ni a matu lang ra ai, PP welding rod hpe polypropylene daw ni a matu lang ra ai. Dai hta n-ga, welding rod diameter hpe weld n-gun hte matut mahkai ra ai. Dai majaw, n-gun rawng ai ni hpe n-gun jaw na matu, 80% hta n jan na matu, rod diameter gaw, n-gun rawng ai hku galaw na matu, madung hku nna hpaji jaw da ai.
Pretreatment gaw awng dang ai welding galaw na matu madung rai nga ai. Welding garai n galaw shi yang, sau, nhpu, oxide layers ni hpe shaw kau na matu, n-gup magap ni hpe atsawm sha jasan jaseng nna, n-gun ja hkra, sandpaper hte n-gun n rawng ai sand hpe shaw kau na matu. Ambient temperature hpe hkang na matu mung ahkyak ai. N law htum- aten ladaw hta, dai arung arai ni a n-gun yawm ai majaw, n-gun n rawng hkra, welding rod hte base material hpe shawng nnan lang na matu hpaji jaw da ai.
Welding galaw ai aten hta, heat gun (sh) soldering magri a n-gun hpe hkrak hkrak hkang ra ai. 250℃kaw nna 350℃du hkra, madung hku nna hpaji jaw da ai nbung katsi ai lam hpe, plastic amyu hta hkan nna, manu ni hpe gram lajang da ai. welding rod hte base material hpe molten state de kalang ta katsi shangun ngut ai hpang, welding rod hpe n-gun n-gun hte rawt jat wa hkra, 15℃kaw nna 30℃du hkra angle hpe n-gun dat nna, n-gun rawng ai plastic hpe hkum tsup hkra shang hkra galaw na matu. Wilding rod hpe grai lawan ai hku shamu shamawt na hpe koi nga u, dai gaw katsi ai weld, shing nrai grai loi ai hku byin shangun chye ai, dai gaw localized grai katsi ai hte n-gun n rawng ai lam ni hpe byin shangun chye ai.
Welding ngut ai hpang, welding rod hpe shingra tara hku katsi hkra galaw nna, nta kata na katsi ai lam hpe n galaw shi yang, shingra tara hku katsi hkra galaw u. Aten garai n du shi yang myit ru myit tsang lam ni hpe jai lang ai gaw weld cracking byin shangun chye ai. Katsi majan hpe hkra machyi shangun chye ai n-gun hpe pat shingdang na matu welding gun nozzle hpe ayan jep yu ai gaw, n-gun n-gun hpe n-gun n-htum hkra galaw na matu mung ahkyak nga ai.
Standardized material lata la ai lam, atsawm sha tsi lajang ai lam, hte hkrak tup galaw ai lam ni hku nna, plastic welding a kam hpa mai ai lam hpe grai kaja hkra galaw lu ai, hpaga lam hte gram lajang ai lam a tsaw dik ai madang ni hpe hkan sa lu ai.
