style="text-indent:25px">修復方法焊前準備工作：用手砂輪將原焊縫裂紋處的油污、油漆、銹蝕等清理干凈。用氣刨機將焊縫裂紋刨割掉，刨割至側板的本體，并將以往焊接的母材淬硬區(qū)清理干凈。刨割后用角砂輪將切口打磨平整(內側接口打磨出V形坡口)，清洗、粉色檢查后，確認裂紋已全部找到并清理干凈。根據(jù)現(xiàn)有維修條件，選用Φ5mm型號為E5015(J507)或E5016(J506)焊條，在350℃溫度下烘烤2h，再在100℃保溫，防止焊條吸潮，隨用隨取;焊接電流190～230A。由于挖掘機側板厚度較大，焊接前應將焊接的部位預熱至150～250℃;在焊接過程中，可采用分段、對稱、倒退法施焊;在焊縫冷卻過程中應不斷用手錘對焊縫金屬進行敲擊，以消除應力;在側板轉角處施焊時，為避免、起落弧缺點，宜連續(xù)施焊，以改善連接處的受力狀況。焊接結束后，徹底清理飛濺物、焊渣和焊瘤等，焊縫余高不得大于2.5 mm。對焊縫進行磁粉探傷檢查，不允許有裂紋等缺點。隨著挖掘機銷量的增長，整個工程機械行業(yè)和基礎設施建設在未來一段時間內，都會是向好的狀態(tài)。</p><div style="width:100%;text-align: center;"><img style="max-width: 640px; max-height: 320px;" alt="呂梁挖機銷售,挖機"
