双丝双弧焊在中厚板焊接的应用

双丝双弧焊在中厚板焊接的应用 Application of double wire and double arc welding of medium and thick plate 罗强 LUO Qiang 1 first-author 甘跃 GAN Yue 1 刘春明 LIU Chunming 1 成都华远电器设备有限公司 成都华远电器设备有限公司 Chengdu Huayuan Electric Equipment Co.,Ltd. Chengdu Huayuan Electric Equipment Co.,Ltd. 针对双丝双弧焊的工艺要求,以某公司双丝双弧焊设备的特点及其应用为例,通过焊接试验得出,双丝双弧焊在焊接20 mm及以下厚度钢板时,可以不开坡口双面焊接,前置焊丝直流保证熔深,后置焊丝交流保证熔敷,可在较高的焊速下获得良好的焊缝成形和焊接质量,适用于普通碳钢及高强度钢中厚板的焊接。 In view of the double wire double arc welding process requirement,taking the characteristics and application of double wire double arc welding equipment of a company as an example,through the welding test,it is concluded that when the double wire double arc welding is used to weld the steel plate with the thickness of 20 mm or less,the groove and double-sided welding can be avoided,the direct current of the front welding wire can ensure the penetration,the alternating current of the back welding wire can ensure the deposition,and the good weld formation and welding quality can be obtained at a higher welding speed It is applicable to the welding of ordinary carbon steel and high-strength steel plate in medium and thick plates. 双丝双弧焊 高效焊接 中厚板 double wire double arc welding high efficiency welding medium and thick plate TG434 2022-03-08 5 50
