摘要
厚板CO_2焊,采用K形坡口可增加焊接厚度,节约填充金属。对单边小坡口,采取将导电嘴伸出喷嘴的办法,焊接板厚可不受限制。
The K groove is used for heavy plate CO_2 welding in order to increase the thickness of plate to be jointed and decrease the deposited weld metal. The method with which the electro-conductor extended out the gas nozzle is applied, so the plate thickness will not be limmited any more.
