[6pack] welding question

[James F Juhas]

I would remove the coating where the weld will be.  The gases that will 
be expelled are toxic, and with good ventilation, may not pose a serious 
threat, but there's no reason to risk it.  the coating may lead to weld 
impurities that would weaken the weld, but again, probably not too much 
a risk in this application.  Like most of us amateur weldors, you're 
going to over-weld anyway, no doubt.  But since the coating will burn 
off anyway, I would remove it first to avoid both potential problems.

I once bought a canopy from a man at Carlisle.  The fittings he made to 
put the poles together were made from electrical conduit, also 
galvanized.  It was obvious from his welds that he never took the time 
to remove the toxic zinc before welding.  He appeared to not be in the 
best of health.

I've wanted to buy another canopy, but he hasn't been back for several 
years now.

I purchased a set of plates and hangers from Northern Tools.? The kit is actually to attach springs to a trailer, but the plate and U-bolts fit my needs perfectly.? The plate is listed as zinc on the package, but has more of a cadmium appearance to it.? It is very smooth.? Do I need to grind this coating (which is clearly not hot dipped zinc) off of the plate before welding, or simply have at it and don't worry about the coating.? I anticipate repainting the entire assembly with an epoxy paint after welding.? I will be using a stick welder.? Thanks for the advice.
