Re: [MW:33487] Re: FW: Welding Superduplex

Greetings,
Below here is major factors:
1. Mixture of Shielding gases (Or + N).
2. Cold Pass Techniques (second pass should be lesser heat input from root pass approximately 75% ).
3. Control heat input with normal root penetration and excess weld-metal.
  4. Filler wire with minimum diameter to reduce heat input.
