Wholesale Discount Mega Welding Rod - Stainless Steel Welding Electrode AWS E309-16 （A302） – Tianqiao
Wholesale Discount Mega Welding Rod - Stainless Steel Welding Electrode AWS E309-16 （A302） – Tianqiao Detail:
APPLICATIONS:
Suitable for welding the same type of stainless steel, stainless steel lining, different steels (such as Cr19Ni10 and low carbon steel, etc.) as well as gaoluo steel, high manganese steel, etc.
CHARACTERISTICS:
E309-16 is a Cr23Ni13 stainless steel electrode for rutile skin pressure equipment. Both ac and DC can be used for all position welding. Excellent welding performance. The deposited metal has good crack resistance and oxidation resistance.
ATTENTION:
1. Before welding, the electrode shall be baked at 320-350℃ for 1 hour and used as needed.
2. Remove rust, grease, moisture and other impurities before welding.
3. DC power supply is recommended, because the depth of current welding is relatively shallow, the current should not be too large, so as to avoid redness and cracking of the skin.
4. Reduce the heat input as much as possible, and the swing amplitude of the electrode should not be too large.
5. Preheat and keep the temperature between channels below 150℃.

Rule inspection:
Welding parts are inspected by the quality inspection department of the manufacturer.
For welds that require radiographic testing, the length of the welds subject to radiographic testing should not be less than 20% of the full length of the welds.
When an impermissible defect in the weld is found, supplementary radiographic testing shall be performed near the defect, and the supplementary radiographic inspection length shall be equal to the length of the radiographically inspected part of the weld. If an unallowable defect is found after supplementary radiographic testing, all welds should be radiographically tested.
For important welding parts, the appearance and geometric shape and size of the weld shall be inspected one by one. In addition to the appearance inspection of welds for general parts, the geometry and dimensions of welds shall also be randomly inspected.
For important parts or important welds of important parts, the requirements for non-destructive testing or sealing test and welding mechanical performance test shall be carried out in accordance with the specifications in the drawings or ordering technical requirements.
