Where are the projection weld bolts and Pins located?
Projection weld bolts and pins feature three precision weld projections located on the head. This design allows for attachment of the fastener from the underside of the panel. The three equispaced projections are of equal height and diameter allowing for a properly balanced and positioned weld.
When to use welds and bolts in a connection?
Provision 2.6.3 states that for rivets or bolts used in bearing-type connections (that is, when the bolt or rivet acts as a pin), the mechanical fasteners shouldn’t be considered as sharing the load in combination with welds. If welds are used, they should be provided to carry the entire load in the connection.
What kind of studs do you need for Weld bolts?
Collets must be the same size as the stud or pin you are welding and are not interchangeable with studs from other systems. Threaded studs are for thin-gauge base materials. 18-8 stainless steel studs are more corrosion resistant than copper-coated steel studs.
How many rows are in a weld bolt?
Weld Studs Base Base 1/2 ” 0.323″ 0.052″ 60,000 Below Head 5/8 ” 0.323″ 0.052″ 60,000 Below Head 3/4 ” 0.323″ 0.052″ 60,000 Below Head

Do you leave the bolt in while you Weld?
The welds are really more like 3 or 4 tacks, as too much heat can distort the nut. Leave the bolt in while you weld to protect the threads of the nut. Then take out the bolt, grind the surface flat, and you are done. I’ve done it a bunch of times, and you can do it quicker than the time it takes to explain it.
How do you put a nut on a bolt?
Put the nut on a bolt (not the one for final assembly, as you may sacrifice the threads) to hold it, put the nut down into the hole you just cut, slighty below flush, and tack it in. Then weld around it to fill the gap. The welds are really more like 3 or 4 tacks, as too much heat can distort the nut.
