Useage For ER307 Stainless steel welding wires:
It is used in special occasions that require non-magnetic properties such as nuclear submarines and bulletproof steel plates, and can also be used for welding of dissimilar steels that are difficult to weld and easy to crack.

ER307 Welding Wire Chemical Composition :

Product Welding Reference Current(AC Or DC+):

NOTE For Product Use:
*Shielding gas: Pay attention to the purity of the shielding gas, and the recommended gas mixture ratio is Ar+1-3%O2.
*Gas flow: 20-25L/min.
*Dry elongation: 15-25mm.
*Really remove the rust layer, moisture, oil, dust, etc. on the welding part.
*During outdoor welding, when the wind speed is greater than 1.5m/s, windproof measures should be taken, and appropriate windproof measures must be taken to prevent the occurrence of blowholes.
The above suggestions are for reference only, and the actual situation shall prevail in the specific operation. If necessary, process qualification should be carried out before determining the welding plan.
