Product Description

工频/中频电阻焊设备 交流金属焊接点焊机厂家
点焊工艺是形成粘接的金属连接。焊接时,焊件通过焊接电流局部加热,并对焊件的接触加热点施加压力以形成焊点。点焊是一种高速、经济的连接方法,它适用于制造搭接接头,接头不需要气密,厚度小于5mm的冲压轧制板材部件。点焊工艺目前应用于各个工业部门,不仅可以焊接低碳钢和低合金钢,还可以焊接高碳钢、高锰钢和不锈钢、铝合金、钛合金等材料组成的零件。

点焊工艺参数的选择:影响点焊的工艺参数包括焊条的结构直径、焊接能量、焊接时间和焊接压力。按焊接速度和焊接效果可分为快焊、中速焊、普通焊三种条件,适用于要求焊接强度高、焊接变形小的场合,采用大功率、短时间强规格的快速焊接。对于要求不那么严格的工件,可以采用功率低、时间长的普通焊接方法,这样就可以选择比较小的焊接设备,对电网的影响也比较小。通常根据工件的材料和厚度进行选择,参考材料的焊接条件表,首先确定焊条的端面形状和尺寸,然后初步选择焊条压力和焊接时间,然后调整焊接电流,用不同的电流焊接试样,然后调整焊条压力, 在检查熔芯直径是否符合要求后,焊接时间和电流在适当范围内。对样品进行焊接和检查,直到焊点的质量完全符合技术条件中规定的要求。测试样品最常用的方法是撕裂法,优质焊点的标志是撕裂样品的一块有一个圆孔,另一块有一个圆凸台。厚板或淬火材料有时不能撕开圆孔和凸台,但可以通过剪切断裂来判断熔融芯的直径。如有必要,还需要进行低功率测量,拉伸试验和X射线检查,以确定穿透率,剪切强度以及是否有缩孔和裂纹。在用样品选择工艺参数时,应充分考虑分流器中样品与工件之间的差异,铁磁性物质的影响以及装配间隙,并进行适当的调整。

影响点焊接头焊接质量的主要因素有焊接电流、焊条压力、焊接时间、预压和休息时间、焊条直径等。
