焊縫熔深 的英文怎麼說
中文拼音 [hànféngróngshēn]
焊縫熔深
英文
weld penetration-
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。So the shape and the penetration of welding bead will change, result in the lack of the penetration
因此焊縫熔深也發生變動，容易產生熔深不足等缺陷。The lack of the penetration of welding bead is a typical defect. it will do great harm to the quality and safety of the welding structure
焊縫熔深不足是焊縫及焊接接頭內部的一個典型缺陷，會給焊接結構的質量及使用安全帶來危害及影響。The effect of the changes of the wire extension on the penetration of welding bead is analyzed and a project of the controlling to the penetration of welding bead is established in this paper
本文分析了焊接過程中由於干伸長的變化對焊縫熔深的影響，確定了熔深控制方案。The penetration of welding bead is hard to be checked directly in practice, so the control on the penetration of welding bead is mainly realized by adjusting the related factors
由於焊縫熔深在實時狀態下難以直接檢測，因此，對焊縫熔深的控制主要是通過調節與其相關量來實現的。The result of the experiment showed that the fuzzy control technology is well compensatory to the penetration of welding bead. the equivalent circuit model established in saber is able to reflect the circuit in practice
實驗結果表明，採用的模糊控制技術對焊縫熔深有較好的補償性， saber模擬軟體所建立的等效電路模型能夠真實的反映實際電路。When the welding current is added, the quality of heat of the arc will increase, so both the volume of molten puddle and the depth of arc crater will all increase, and the weld depth will increase when the weld is cooling
焊接電流增加時，電弧的熱量增加，因此熔池體積和弧坑深度都隨電流增加，所以冷卻下來后，焊縫厚度就增加。分享友人
