摘要：
The purpose of the present invention is, in gas shielded arc welding using an active gas and flux-cored wire with primer-coated steel plates as a base material, to suppress occurrences of poor appearance in welded parts caused by pores originating in the primer. A welding method for a welded article positions a first steel plate and a second steel plate formed from primer-coated steel plates in a T shape and welds each of corner parts formed in two locations. Using flux-cored wire (100), which is formed by filling the inside of a steel outside skin with flux, and a shielding gas (carbon dioxide gas), a welding pool (400) is formed in the corner part by supplying a welding current to the corner part via an arc from the flux-cored wire (100) by means of the shielding gas; additionally, an alternating magnetic field is applied to the welding pool, and the welding current and the alternating magnetic field are set such that the welding current (A) and the magnetic flux density (mT) for the alternating magnetic field have a relationship of 20000 ≤ welding current × magnetic flux density ≤ 30000.
摘要（中）：
本发明的目的在于使用以底漆涂覆钢板作为基材的活性气体和药芯焊丝的气体保护电弧焊接，以抑制由底漆产生的孔引起的焊接部位外观不良的发生。 本发明提供一种焊接物的焊接方法，将由底漆涂装钢板形成的第一钢板和第二钢板定位为T字形状，并对形成于两处的角部进行焊接。 使用通过用熔剂填充钢板外表面内部而形成的药芯焊丝（100）和保护气体（二氧化碳气体），通过供应焊接在角部形成熔池（400） 利用保护气体经由来自药芯焊丝（100）的电弧向拐角部分通电; 另外，对焊接池施加交变磁场，并设定焊接电流和交变磁场，使得交变磁场的焊接电流（A）和磁通密度（mT）具有20000的关系 ≤焊接电流×磁通密度≤30000。
