AWS A5.4 E312-16

ISO 3581-B-ES 312-16

Characteristics and Application

titanium calcium AWS A54 E312-16 can be used for the welding of high carbon steel, tool steel and dissimilar metal Features: it is a coated titanium calcium type of duplex stainless steel electrode. It can reach excellent welding performance and both AC and DC can be used. It also has excellent crack resistance due to the weld contains about 40% of the ferrite.

Welding Positions:

Notes on usage:

1 Electrode must be approved by 350-380℃ for 1 hour before welding, dry the electrode when use it.
2.The rust, oil, water and other impurities of the weld must be removed before welding.

3.Recommended DC power supply, because AC welding has a shallow penetration, the current should not be too large, in order to avoid the coating redness and cracking.
4. To minimize the amount of heat input and welding electrode oscillating amplitude should not be too bigo
5.Preheat and interlayer-temperature should remain below 150℃
