焊接工艺注意事项：

1、氩弧焊焊接工艺参数的选择（包括电流、气体流量、钨极伸出长度等）应根据工件材料的种类、厚度、接头形式，焊接位置及自身的实际情况进行综合考虑后选择。

2、焊接前要及时清理工件表面的油污、水份等杂质，以免影响焊接质量。

3、一般情况下，当电流在100A~200A时，气体流量在9~14L/min为宜；当200A~300A时，气体流量在14~18L/min为宜；钨极伸出长度为3~5mm，弧长1~3mm；风速≥1.0m/s时应及时采取防风措施的。建议在焊接区背面通氩气保护。

4、焊接线能量的大小直接影响焊缝的力学性能，用户应根据实际情况及时进行调整。

5、以上建议仅供参考，用户在使用前，应根据自身的实际情况进行工艺评定。

焊丝搬运及贮存：

1、简装氩弧焊丝在搬运时，应轻拿轻放，避免碰坏塑料包装而使焊丝变形，影响使用。

2、氩弧焊丝怕水，不可近火，不而高温，贮存时应特别注意。

3、一筒焊丝在未使用完而需要保存时，应及时把塑料筒密封好，以防生锈。

4、仓库贮存时，离墙壁距离应大于30cm为宜，应按规格、型号摆放清楚，防止混用，并按“先进先出”的原则合理使用。
