厚壁無縫管制作工藝不當的表現

　　厚壁無縫管材料：汽車底盤為，葉子為焊接方法：電弧焊接，焊接前不加熱，焊后不淬火電焊焊接主要參數：電焊焊接電流量=，電焊焊接速率=。焊材：焊絲，焊絲直徑。實際效果：對接焊縫上色檢測無缺點，運作2年多未發現問題沉積硬底化不銹鋼的焊接案例不銹鋼板壓力容器環縫的電焊焊接壓力容器材料為不銹鋼板，壁厚為，有機化學，氬孤焊和電弧焊用焊條成份均與對接焊縫同樣，直徑均為，助焊劑型號為。焊接件焊接前開展噴砂工藝，用手工制作鎢氬弧焊機開展精準定位，不填焊條，精準定位距離為，連接處空隙不超，將精準定位焊后的球型器皿放置專門的電焊焊接轉胎上選用全自動鎢氬弧焊機內搭，選用埋弧自動焊機添充蓋面，焊接方法主要參數見，電焊焊接后的壓力容器連接頭抗壓強度超過原材質的，沖擊性韌性做到原材質的。
