application of CD weld pins

1. CD welding pins is a insulation fastener which is used to fasten the insulation materials to sheet metal of air duct, other heating, ventilating or air conditioning.

2. A fabricated part made up of a weld pin and a staked on retaining washer,it is usually applied with a capacitor discharge stud welder.

3. The method of application is to place the insulation onto a metal surface, push the weld pin through the insulation, and weld affix (mount) the entire fabricationin one step. Now it is widely accepted as labor saving fasteners in the thermal and acoustical insulation markets for use in industrial and commercial applications.
