| 試驗(yàn)采用大角度(7°)和小角度(3°)內(nèi)管接頭兩種方式進(jìn)行放電,目的是為了研究不同的撞擊速度下焊接界面的特性。經(jīng)研究,兩種角度下,通過(guò)尋找均發(fā)現(xiàn)在焊接接頭某些位置間歇性出現(xiàn)這種特殊波峰,且波峰偏向焊接方向,在波峰上面清晰的可以看到有過(guò)渡區(qū)的存在,這個(gè)現(xiàn)象說(shuō)明過(guò)渡區(qū)早于或同時(shí)與波峰形成。同時(shí)發(fā)現(xiàn),無(wú)論是角度大還是小,這種特殊的波峰后面均出現(xiàn)過(guò)渡區(qū),過(guò)渡區(qū)的寬度與波峰傾倒后的高度一致。對(duì)過(guò)渡區(qū)多個(gè)位置進(jìn)行能譜分析發(fā)現(xiàn)該區(qū)域是鋁和鋼金屬的混合區(qū),沒(méi)有發(fā)現(xiàn)金屬間化合物。 |

To study the characteristics of the weld interface under different impact velocity , two different discharge ways of large angle (7 °) and small angle (3 °) in the pipe joint were analyzed . This certain particular peak were found in some locations intermittently of welded joint in both angles and skewed to the welding direction with a clear presence of a transition zone .The phenomenon can be described as that the district was prior to or simultaneously with the formation of the crest. At the same time , no matter big or small angle, this particular transition zone appears behind the crest and the width of the peak is equal to the height of the transition zone after reversal. The EDS analysis of multiple transition areas revealed that the area is a mixture of aluminum and steel metal area and no Metals and metal compounds was found . 金屬間化合物 看看翻譯對(duì)沒(méi)? |
