(OP)
Does anybody knows what is the reason that if you have galvanized pipe, you have to have galvanize free end for welding? Is it a quality of weld or it is cancer gasses that are released while welding?

Zinc can cause cracking in welds. It is best to remove it first by grinding or burn it off with an oxidizing flame.
Same health problems.
If you must weld over it,try E6010 or perhaps GMAW short arc
with CO2. It may also require a wider root gap.

"Harm Caused by Welding Fumes Is Receiving Greater Recognition.
Welders who have been harmed by the gases and metal fumes created in the welding process have begun to bring legal actions against various parties, including the companies that provided the welding equipment and supplies, to recover for their injuries.
Over the past 30 years, our team has been responsible for bringing justice and distributing millions of dollars to thousands of clients from class action and individual settlements."
