How To Weld A Nut To Sheet Metal

Weld fasteners are ideal for applications which require a threaded fastener that is more sturdily attached to a sheet metal surface than a self clinching fastener or rivet nut.

How to weld a nut to sheet metal.

When welds appear satisfactory on installed nut but pushout values are low one or more of the following may be the cause. Stick welding otherwise known as shielded metal arc welding smaw stick welding is a two handed method like tig. Don t attempt to weld thin materials like sheet metal with flux cored wires which put more heat into the base metal. Insufficient electrode force.

Nut welding using marc 1 nut welding system. Today we show the verycoolgang 3 different ways to attach two pieces of m. Soldering is one method that is widely used to accomplish this. The hex weld nut is suitable for a wide range of heavy duty applications while tab nuts are best for lighter applications.

Projection and spot are the two main classes of weld nuts. To weld sheet metal with solid wires use electrode positive ep or reverse polarity. 3 ways to attach metal to metal without welding. Tradesmen often use brazing or welding instead to create stronger joins between the metals.

Weld fasteners can be utilized in light medium or heavy industrial manufacturing to produce a wide range of products including. While soldering is useful for many purposes it has limitations. Like with riveting you just need two pieces of metal with proper size holes in it. Stick welding uses a metal filler rod or stick coated with flux.

As the stick material melts in the heat the flux coating also melts creating both a gas and a liquid slag which act to shield the weld from oxidation. Sometimes it is wise to use washers as well to avoid damaging the metals. Once you have the holes you just stick the bolt through the hole and screw on the nut on the other end. You can attach a right angled weld nut to the base metal to create a threaded hole which should be aligned vertically to the surface.

Forget the larger 1 8 inch tungsten electrode and use a smaller one. Electrodes weld nuts and panels must be clean and free of grease rust and metal burrs. It can be accomplished with a regular drill.
