Weld beads metal and welds - fatigue tests 焊縫金屬和焊接接頭的疲勞試驗(yàn)法
A cavity is made on both sides of weld bead 在焊道表面兩側(cè)作一空腔。
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(fā)生變動(dòng),容易產(chǎn)生熔深不足等缺陷。
Using the heat of welding to vapour water , cooling rates are lowered on the weld bead and heat - affected zone 利用焊接時(shí)的加熱使水汽化,不僅使焊道而且使熱影響區(qū)的冷卻速度減慢。
As is known to all , the protecting effect of tig welding is fine . the metal in welding bead is pure 眾所周知, tig焊焊縫保護(hù)效果好,焊縫金屬純凈,特別適用于焊接易氧化的有色金屬及其合金。
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(nèi)部的一個(gè)典型缺陷,會(huì)給焊接結(jié)構(gòu)的質(zhì)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于干伸長(zhǎng)的變化對(duì)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 由于焊縫熔深在實(shí)時(shí)狀態(tài)下難以直接檢測(cè),因此,對(duì)焊縫熔深的控制主要是通過調(diào)節(jié)與其相關(guān)量來實(shí)現(xiàn)的。
Using 304l wire as the cladding material , the experimental results proved that the relationship among welding bead width , welding current and speed could be expressed with a plane in an x - y - z coordinate 對(duì)采用304l不銹鋼作為單一熔覆材料的成形試驗(yàn)研究表明:電流、成形速度與成形軌跡寬度的關(guān)系可以采用平面幾何關(guān)系表示。
