（１）大力发展高效焊接方法，高效MAG焊，高效埋弧焊和高能束焊。目前，在国际上对高效焊有了新的定义，即熔敷率达到和超过１５kg／h的焊接方法才算作高效焊。为此，国外已开发成功旋转喷射电弧高效MAG焊、多丝MAG焊、等离子弧－MIG复合焊接法、大电流一次成形埋弧焊、双丝埋
(1) To develop efficient welding methods, efficient MAG welding, high efficiency submerged arc welding and high beam welding. At present, the international community for a new definition of efficient welding, that is, deposition rate and more than 15kg / h welding method is considered as efficient welding. To this end, foreign countries have successfully developed high-performance rotary jet arc welding MAG, multi-wire MAG welding, plasma arc-MIG composite welding, forming a large current submerged arc welding, double wire buried
