Dear philip,
1. need to calculate the weld metal deposit
normally pipe wall thickness x2 times only you need deposit the fillet weld
2. main issue is heat input and inter pass temperature you need to maintain during welding
3. for gas line dont use the electrical resistance method try to use burners
4. prefer the vertical down method welding if it is 5G position.
Regards,
Srinivasan.M
