Does weld-thru primer work?
During the welding process, the weld-thru primer liquefies and galvanizes the metal around the weld which helps protect the metal from future corrosion. It helps provide permanent rust protection on the inner edges of the welded metal pieces.
What is the purpose of weld through primer?
These primers are generally applied prior to the welding process. The purpose of a weld through primer is to prevent corrosion and rusting of metal joints where two metal pieces are welded together and provide permanent corrosion protection on the inner edges of the welded metal pieces.
Can I weld through zinc primer?
Weld-through primer is a zinc-based product that protects welds from corrosion. It should be used between welded metal panels. Unlike most primers, weld-through primers don’t promote adhesion, but instead provide sacrificial corrosion.
Can you spot weld through weld through primer?
Weld-through primer was still allowed for squeeze-type resistance spot welding, Tobie said. There’s enough current in such joining that the joint holds “no matter what,” he said. You still have to properly prep the metal surfaces being welded, of course, he said.
Is weld thru primer waterproof?
Water resistant after 15 minutes. Weld-through paint in 30 minutes.

Should you weld on rust?
Can you weld rusty metals? You can weld rusty metals if you have the proper welding process and consumables for the job at hand. However, you cannot weld rusty metal for critical work because rust lowers the tensile strength and causes many defects.
Why do my welding rods stick?
A stick welding rod sticks because the arc’s heat is not high enough to prevent the fusion between the molten rod and the puddle. Having low amperage settings or an arc length that is too short are the main reasons.
Why are my stick welds not holding?
When would you use a 6013 Rod?
6013 Welding Rods The 6013 electrode is best used for light to medium penetration on thin or sheet metal pieces. 6013 electrodes are commonly used in manufacturing truck frame bodies, metal furniture, storage tanks, farm implementations, or where aesthetics are of grave importance.
