 电焊机缺点在使用的过程中焊机的周围会产生一定的磁场,电弧燃烧时会向周围产生辐射,弧光中有红外线,紫外线等光种,还有金属蒸汽和烟尘等有害物质,所以操作时必须要做足够的防护措施。焊接不适合于高碳钢的焊接,由于焊接焊缝金属结晶和偏析及氧化等过程,对于高碳钢来说焊接性能不良,焊后容易开裂,产生热裂纹和冷裂纹。低碳钢有良好的焊接性能,但过程中也要操作得当,除锈清洁方面较为烦琐,有时焊缝会出现夹渣

逆变电焊机电源的谐波抑制分析[2017-05-25]
一、 逆变器及逆变式弧焊电源  将直流电转换成交流电的装置称逆变器。  其变换顺序可简单地表示为:工频交流(经整流滤波)→直流(经逆变)→中频交流(降压、整流、滤波)→直流。如果用符号表示,即为:  AC→DC→AC→DC  一般都采用上述这种体制。这是因为如果直接用逆变降压后的交流电进行焊接,由于其频率高,则感抗大,在焊接回路中有功功率就会大大降低。因此,还需再次进行整流。  二、 逆变电源的特
逆变电焊机的电源特点[2017-05-25]
逆变电焊机的基本特点是工作频率高,由此而带来很多优点。这是因为变压器,无论是原绕组还是副绕组,其电势E与电流的频率f、磁通密度B、铁芯截面积S及绕组的匝数W有如下关系:  E=4.44fBSW  而绕组的端电压U近似地等于E,即:  U≈E=4.44fBSW  当U、B确定后,若提高f,则S减小,W减少,因此,变压器的重量和体积就可以大大减小。这样,就能使整机的重量和体积显著减小。不仅如此,还因为
剥线机操作规程[2017-05-25]
剥线机操作规程:1.使用机器前,必须先详细了解机器性能和操作规程,然后按顺序进行操作。2.将进气管接入气源0.4-0.6Mpa,并将电磁阀插头插入220V50Hz电源。踩踏脚踏开关,检查电源气源接通是否正常。3.根据工艺要求调节机器,调节好后,完成剥线/剥皮动作。开机工作时,靠近运动部件周围不得堆放杂物及工具。4.工作完毕后,切断电源。及时清理设备表面周围的杂物及卫生,保证良好的工作环境,确保人身
