Even though the remaining zinc continues to provide some protection to the zinc-free areas, the appearance is poor and the zinc-free area will rust when exposed to the environment.
Zinc has a relatively low boiling temperature compared to steel, but to weld a coated steel your welding torch will need to meet the required higher temperature for steel welding. The effect of this in practice is that when welders start work on these materials, the zinc is vaporized and becomes trapped in the steels.(plate) Internal coating pipes, Internal coating pipeline(steel) Internal coating pipes. using epoxy powder coating is for 30 years of history in a foreign country due to the wide range of sources of raw materials, production methods are simple, cheap, good performance, which do not pollute the environment and long service life, so far it is a good anti-corrosion coatings.(plate) Liquid Metal Embrittlement of Austenitic Stainless Steel zinc coating welding rectangular steel(steel) stainless steel welded to galvanized steel, the zinc coating must be scrupulously removed from the joint area prior to welding BY R.
