Thank You Jop,
I understand about Field Weld and Fit field weld,
But sir this doubt rise in mind when one of my superior told me to have defult FW when any size pipe having platform penetration to ease off construction. is it ok.
In view of this I have one doubt,
1) whether grating or chequred plate use maximum for platform.
2) whether piping installed first , then this gatings or chequred plate.
3) where grating or chequred plate installed first tehn piping , if third option is ok then my superior might be right,

Please share your experience.
