焊接材料消耗定额标准.doc

. 焊接材料消耗定额标准 Q/HZ MB103-79 二零零四年十月 使用说明：1 本标准以焊接1米焊缝所消耗的焊接材料重量为单位（即kg/m），用于生产时须乘上该产品焊缝的实际长度。2 手工电弧焊的焊条消耗定额标准分碱性焊条和酸性焊条两种，计算时需按产品实际所用的焊条选用之。3 本标准的计算时先算出焊缝横截面积，再算出每条焊缝的熔敷金属重量，然后标出每米焊缝的焊丝，焊剂或焊条的消耗量。酸性焊条按熔敷金属重量的 1.65倍计，焊丝按酸性焊条重量的0.636倍计；碱性焊条按熔敷金属重量的 1.80倍计，焊丝按碱性焊条重量的0.583倍计； 焊丝按熔敷金属重量的 1.05倍计； 焊剂按熔敷金属重量的 1.35倍计； 一 不开坡口单面手工焊缝 焊缝尺寸熔敷金属kg/m定额（kg/m） c b e截面积酸性焊条碱性焊条104130.0230.0380.0411.505140.0310.0510.056216160.0470.0780.085318190.70.1150.126二 不开坡口双面手工焊缝 焊缝尺寸熔敷金属kg/m定额（kg/m） c b e截面积酸性焊条碱性焊条3181140.1090.180.19642101210.1640.270.2954.52101220.1720.280.3152121260.2040.340.3762141300.2350.390.4282.5161.5510.4000.660.72102.5181.5570.4480.740.81三 V型坡口单面手工焊缝 焊缝尺寸熔敷金属kg/m定额（kg/m）pcbe截面积酸性焊条碱性焊条370011.58112.60.0980.1620.176470011.58117.60.1370.2260.247570011.510125.30.1970.3250.355670022.510132.80.2560.4230.460870022.5141.559.20.4620.7630.8301065022.5161.585.80.6701.1101.2101265022.5181.51180.9201.5241.6601465023201.51761.3702.2602.470 四 V型坡口双面手工焊缝 焊缝尺寸熔敷金属kg/m定额（kg/m）pcbb1e=e1截面积酸性焊条碱性焊条570022108128.30.2210.3650.398670022108135.20.2740.4520.49487002214101.565.20.5100.8410.920106502216101.586.70.6760.1201.220 五 对称双面X型坡口手工焊缝 焊缝尺寸熔敷金属kg/m定额（kg/m）pcbe截面积酸性焊条碱性焊条126502312183.80.6651.081.181465023141104.40.831.371.491660023151.5134.51.051.731.892060023161.5185.51.452.392.612260023171.5215.51.682.773.022560023191.5265.52.073.423.722860023211.53212.504.124.503060023221.5359.52.804.625.053260023231.54023.195.165.743660023261.54933.846.356.914065023282610.64.767.858.564660023312810.66.3110.411.355060023342905.67.0611.6512.75六 单面U型坡口手工焊缝焊缝尺寸熔敷金属kg/m 定额（kg/m）be截面积酸性焊条碱性焊条12161.51481.161.922.0914161.51801.412.342.5416201.52191.722.843.10242222823.004.955.40262424293.365.556.0518201.52552.003.303.60202223022.373.924.28222223412.674.404.80282424733.726.156.70302425194.086.757.35七 不开坡口丁字接头单面手工焊缝焊缝尺寸熔敷金属 kg /m 定额（kg/m）ke截面积焊 丝酸性焊条碱性焊条22140.03120.03280.05150.056233180.06250.06560.1030.113441120.09360.09830.1550.169551180.140.1470.230.252661.5270.210.2210.3470.378771.5350.2750.2890.4540.495881.5440.3440.3610.5680.62991.5540.4240.4450.700.76310101.5650.510.5360.8430.9211111.5770.6040.6340.9971.08712121.5900.7030.7381.161.2713131.51040.820.8611.351.4814141.51190.930.9771.530.6815151.51351.061.1131.751.9116161.51521.191.251.972.1418181.51891.481.5542.442.6720201.52301.81.892.973.24222222862.232.3423.684.02242423362.642.7724.364.75252523632.832.9724.675.1282824483.53.6755.776.3303025104.04.26.67.2 注：双面焊定额加倍. 1.八 单面V型坡口角度手工焊缝（双面焊）焊缝尺寸熔敷金属kg/m 定额（kg/m）bek截面积酸性焊条碱性焊条481323.20.1810.2990.3265913300.2340.3860.4216111338.70.3020.500.5448141.5572.70.5670.9351.0210171.55100.70.7851.301.4112201.55134.51.051.731.8914231.551741.362.242.4516261.572311.802.973.24203227349.12.724.54.9223427410.33.25.285.76253827515.64.026.657.25284227633.54.938.158.9304627721.35.629.310.1九 油缸缸底焊缝焊丝定额dd外d1H焊缝长度(m)焊丝重量(Kg)每米焊丝定额(Kg)a63836730.2360.1140.484020.120.4911520.10.4140896720.2450.180.71307120.2520.130.510801028420.2930.150.5101070.3010.230.77010012110420.3540.170.4601271040.3630.240.6701050.3650.260.71201090.3710.190.51011013311420.3880.220.55400.370.9444512514612920.4320.20.45901521290.4420.340.7700.410.92415159X201290.4530.681.4915140168X1814430.490.460.933020.410.83016814620.4940.360.72016414420.4840.30.605016820.490.491.0015160194X2116420.5630.71.2300.841.49151680.5690.661.150180219X2418420.6341.041.6301.261.98151860.6370.931.460200245X2820420.7061.532.1701.882.66152060.7091.41.9801.722.4215230273X2823420.7971.581.9801.932.42152360.81.441.8001.762.20152380.8031.311.6301.591.9815250299X3025420.8692.242.5802.753.1615CG1-30型气割机 切割规范割嘴编号切割厚度mm氧气压力MPa乙炔压力MPa切割速度mm/min0 05100.200.300.0360045001020480380120300.250.3540032023050350280350700.30.40.04300240470902602005901200.40.5210170钢板常用材料：A3、A3F、B3F、20、35、45、16Mn、16MnCu、15MnV常用厚度：5、6、8、10、12、14、16、18、20、22、25、28、30、32、36、40、46、50、60碳当量计算公式(国际焊接学会):Ceq=C+Mn/6+(Cr+Mo+V)/5+(Ni+Cu)/15 (%)当Ceq0.4%时,焊接接头淬硬倾向大,易出现冷裂纹,需预热.Ito-Bessyo计算预热温度公式:T0= T0 预热温度（） C=CX+CP 尺寸碳当量： CP=0.005SCX （S为板厚） 成分碳当量： CX=C+（Mn+Cr）/9+Ni/18+7Mo/90钢板最小弯曲半径板 材弯 曲 半 径经 退 火不经退火钢Q235、15、30钢A5、35钢45铜铝0.5t0.8tt0.2tt1.5t1.7t0.8t0.8t圆钢最小弯曲半径圆钢直径d681012141618202530最小弯曲半径R468101214注：圆钢在冷弯曲时弯曲半径一般应使Rd，在特殊情况下允许采用表中的数值钢管最小弯曲半径管子弯曲工垫管外径d弯曲半径R备注钢管热 弯任意值3d(1)L为管端最短直管长度,一般L=2d,但应45mm(2)单位:mm冷弯焊接钢管任意值6d无缝钢管520壁厚24d壁厚23d20355d3d35604d601405d铜管冷弯182d铝管183d钣金展开公式L=(0.5R+Y系数T)(/90)L: 钣金展开长度;
