【文章內(nèi)容簡介】 焊焊接時注意不要焊偏。每層焊完后應認真清除熔渣，如發(fā)現(xiàn)表面存在缺陷應用砂輪清除后進行補焊，并修磨平整，再繼續(xù)施焊。焊件施焊前，應在始焊處100mm范圍內(nèi)預熱到100125℃以上。定位焊采用熔化極氣體保護焊，焊接材料為THY51A。 接頭焊接工藝卡編號HJ01接頭形式對接焊接工藝評定報告編號PQR02B母 材Q345EZ25厚度，mm53Q345EZ2553焊 縫金 屬厚度，mm焊工持證項目SAW1G（K）07/09 焊接位置平焊層焊接方法填充材料焊接電流電弧電壓(V)焊接速度(m/h)線能量(kJ/cm)背面清根方式碳弧氣刨、砂輪機牌 號直徑極性電流(A)預熱溫度(℃)≥1003SAWH10Mn2/SJ101Φ4DC5506302831層間溫度(℃)100～1406SAWH10Mn2/SJ101Φ4DC5506302831焊后熱處理消除應力9SAWH10Mn2/SJ101Φ4DC5506302834后 熱112SAWH10Mn2/SJ101Φ4DC5506302834鎢極直徑114SAWH10Mn2/SJ101Φ4DC5506302835噴嘴直徑脈沖頻率脈寬比(%)氣體成分氣體流量 編制： 年 月 日 審核： 年 月 日Joint Welding Procedure CardJoint sketch：Note: For butt welding with differenrt thickness,the thickner position should be tapered as per drawing.Operation notes：The bevel angle and clearance shall ply with technology requirement.Do not appear slanting welding during SAM.Clean carefully the slag after welding each layer, if there is surface defect, clean with grinding wheel and then welding repair, polish to flat, then continue welding.Preheat within range of 100mm of the welding starting position to above 100℃ 125℃ before welding.Tacking welding with GMAW, welding consumable is THY51A。Joint Welding Procedure Card No.HJ01Joint typeButtweldingPQR No.PQR02Bbase metalQ345EZ25thickness，mm53Q345EZ2553Weld metalthickness，mmweldercertifieditemSAW1G（K）07/09 welding positionflat weldinglayerwelding methodfilling materialwelding currentarc voltage (V)speed (m/h)energy input (kJ/cm)Back gouging methodCarbon arc gouging、grinding wheelbranddiameterpolaritycurrent (A)preheat temperature (℃)≥1003SAWH10Mn2/SJ101Φ4DC5506302831interlayer temperature (℃)100～1406SAWH10Mn2/SJ101Φ4DC5506302831postweld heat treatmentEliminate stress9SAWH10Mn2/SJ101Φ4DC5506302834post heat112SAWH10Mn2/SJ101Φ4DC5506302834tungsten electrode diameter114SAWH10Mn2/SJ101Φ4DC5506302835nozzle diameterimpulse frequencypulse width ratio (%)gas ingredientgas flow Prepared by：Wang Peng August 5th ,2011 Reviewed by： year month day接 頭 焊 接 工 藝 卡接頭簡圖：注：對于不等厚的對接，較厚處按圖紙削薄。操作注意事項：坡口角度及間隙要符合工藝要求。埋弧焊焊接時注意不要焊偏。每層焊完后應認真清除熔渣，如發(fā)現(xiàn)表面存在缺陷應用砂輪清除后進行補焊，并修磨平整，再繼續(xù)施焊。焊件施焊前，應在始焊處100mm范圍內(nèi)預熱到100125℃以上。定位焊采用熔化極氣體保護焊，焊接材料為THY51A。 接頭焊接工藝卡編號HJ02接頭形式對接焊接工藝評定報告編號PQR02B母 材Q345E厚度，mm41Q345E41焊 縫金 屬厚度，mm焊工持證項目SAW1G（K）07/09 焊接位置平焊層焊接方法填充材料焊接電流電弧電壓(V)焊接速度(m/h)線能量(kJ/cm)背面清根方式碳弧氣刨、砂輪機牌 號直徑極性電流(A)預熱溫度(℃)≥1003SAWH10Mn2/SJ101Φ4DC5506302831層間溫度(℃)100～1406SAWH10Mn2/SJ101Φ4DC5506302834焊后熱處理消除應力8SAWH10Mn2/SJ101Φ4DC5506302834后 熱10SAWH10Mn2/SJ101Φ4DC5506302835鎢極直徑噴嘴直徑脈沖頻率脈寬比(%)氣體成分氣體流量 編制： 年 月 日 審核： 年 月 日Joint Welding Procedure CardJoint sketch：Note: For butt welding with differenrt thickness,the thickner position should be tapered as per drawing.Operation notes：The bevel angle and clearance shall ply with technology requirement.Do not appear slanting welding during SAM.Clean carefully the slag after welding each layer, if there is surface defect, clean with grinding wheel and then welding repair, polish to flat, then continue welding.Preheat within range of 100mm of the welding starting position to above 100℃ 125℃ before welding..Tacking welding with GMAW, welding consumable is THY51A。 Joint Welding Procedure Card No.HJ02Joint typeButtweldingPQR No.PQR02Bbase metalQ345Ethickness，mm41Q345E41Weld metalthickness，mmweldercertifieditemSAW1G（K）07/09 welding positionflat weldinglayerwelding methodfilling materialwelding currentarc voltage (V)speed (m/h)energy input (kJ/cm)Back gouging methodCarbon arc gouging、grinding wheelbranddiameterpolaritycurrent (A)preheat temperature (℃)≥1003SAWH10Mn2/SJ101Φ4DC5506302831interlayer temperature (℃)100～1406SAWH10Mn2/SJ101Φ4DC5506302834PWHTEliminate stress8SAWH10Mn2/SJ101Φ4DC5506302834post heat10SAWH10Mn2/SJ101Φ4DC5506302835tungsten electrode diameternozzle diameterimpulse frequencypulse width ratio (%)gas ingredientgas flow Prepared by：Wang Peng August 5th ,2011 Reviewed by： year month day接 頭 焊 接 工 藝 卡接頭簡圖：注：對于不等厚的對接，較厚處按圖紙削薄。操作注意事項：坡口角度及間隙要符合工藝要求。埋弧焊焊接時注意不要焊偏。每層焊完后應認真清除熔渣，如發(fā)現(xiàn)表面存在缺陷應用砂輪清除后進行補焊，并修磨平整，再繼續(xù)施焊。焊件施焊前，應在始焊處100mm范圍內(nèi)預熱到100125℃以上。定位焊采用熔化極氣體保護焊，焊接材料為THY51A。 接頭焊接工藝卡編號HJ03接頭形式對接焊接工藝評定報告編號PQR02B母 材Q345E厚度，mm39Q345E39焊 縫金 屬厚度，mm焊工持證項目SAW1G（K）07/09 焊接位置平焊層焊接方法填充材料焊接電流電弧電壓(V)焊接速度(m/h)線能量(kJ/cm)背面清根方式碳弧氣刨、砂輪機牌 號直徑極性電流(A)預熱溫度(℃)≥1003SAWH10Mn2/SJ101Φ4DC
