焊缝金属射线探伤要求：Ⅰ级
注意事项及操作要点：
1. 焊接处须彻底清除油污、铁锈、水份等表面杂质，以防止焊接时产生气孔、裂纹等，清理时，坡口面及周围要磨出金属光泽。
2. 焊前应清除焊丝表面的油、垢及锈等污物。
3. 为使焊缝获得良好的机械性能，MIG焊接的保护气体建议采用Ar+2%O2，保护气体流量以20-25L/min为优。TIG焊接的保护气体建议采用纯氩气保护，纯度要在99.99%以上，保护气体流量以8-15L/min为宜。
4. 在焊接过程中，焊接线能量的大小直接影响焊缝金属的力学性能及抗裂性能等，应引起更多关注。
5. 以上焊接方法、条件及规范的建议仅供参考，用户在将焊丝用于正式产品焊接前应根据自身焊接特点进行工艺评定。
