脈沖點焊 的英文怎麼說
中文拼音 [màichōngdiǎnhàn]
脈沖點焊
英文
impulsed spot welding-
Pulse electric current heat treatment ( pecht ) developed by sodick, ltd., of japan, is a recently developed material processing method which consists of spark plasma sintering and welding, plasma activated sintering and welding, big pulse electric current ( bpec ) diffusion welding etc. the following are basic merits of pecht : rapid heating and cooling ; short sintering or welding time ; lowering sintering or welding temperature
脈沖電流熱加工（ pulseelectriccurrentheattreatment ，比如燒結，焊接等）是九十年代發展起來的一種材料快速制備新技術，它包括放電等離子燒結與焊接、等離子活化燒結與焊接、脈沖大電流擴散焊接等。它具有升溫、降溫速度快、能在較低的溫度下燒結或焊接以及時間短的特點。In this thesis, a high - frequency variable polarity arc welding power supply was investigated, which consisted of two independent power sources, the variable polarity power supply and the high - frequency pulse one, having advantages both of them
本文針對鋁合金焊接研製了一種新型電源，所研究的高頻變極性弧焊電源採用雙電源結構，由變極性電源和高頻脈沖電源組成，綜合了兩者的優點。The dcep mig has the characteristic of deeper penetration which can reduce defective fusion and good arc stabilization. the dcen mig has the characteristic of shallow penetration of welding seam, and the welding wire has a high melting speed. so the variable polarity pulsed mig is a new technology for the welding of aluminium alloy sheet
變極性脈沖mig焊是一種新的焊接工藝方法，其綜合了dcep脈沖mig焊熔深較大、可以減少焊縫的熔合不良、電弧穩定性好和dcenmig焊焊縫熔深淺、焊絲熔化速度較快的特點，減小了焊縫的熔深，增加了焊絲的熔化速度，是一種適合於薄板鋁合金焊接的新方法。Why pecht is so quick is a hot topic and many scholars are trying to explain it by proving plasma generating
脈沖大電流燒結、焊接為什麼如此之快是各國研究人員探索的熱點，多數學者從證明形成等離子的角度來解釋這一現象。分享友人
