What is Tack Welding? Uses and Working

Tack Welding

Have you ever seen two pieces of metal connected together and wondered how they got there? The answer might be tack welding. Tack welding is a type of welding that is used to join two pieces of metal together in a way that holds them while other, more permanent welds are made. In this article, we’ll explore the basics of tack welding, why it’s so important, and what you need to know to get started.

What is Tack Welding?

Tack welding is a quick, simple welding process in which two or more pieces of metal are joined together with a series of small welds. It’s commonly used for joining thin sheet metals such as car body panels or for connecting thick steel frames for structural applications. The most common types of tack welding are arc welding and gas metal arc welding (GMAW). Arc welders use an electric current to create an arc between an electrode and the workpiece, while GMAW uses an inert gas to shield the weld from oxidation.

Tack Welding Uses

Tack welding has numerous applications in many industries, including automotive repair, plumbing, construction, shipbuilding and manufacturing. It can be used on both thin sheet metals such as aluminium or stainless steel, as well as thicker steel plates used in structural applications. Some common uses include connecting thin sheet metals together before spot-welding them, creating temporary joints before permanent ones can be made, joining large frame components together prior to full fillet welds being completed and pre-alignment of parts prior to final assembly.

Tack Welding Working

To begin with tack welding, you will need a good quality welder, such as an arc welder or GMAW system. You also need safety equipment such as safety glasses and gloves as well as appropriate personal protective equipment (PPE) like respirators when working with hazardous materials like paint or fumes. When working with thin sheet metals, make sure you have clamps to hold them in place before tacking them together; this will ensure proper alignment throughout the entire process. Finally, always practice good housekeeping techniques by keeping your workspace clean and ventilated at all times.


Tack welding is a great way to join two pieces of metal together quickly and easily without having to make permanent welds right away. It’s often used when joining thin sheet metals or larger structural components before making more permanent welds later on down the line. To get started with tack welding, you will need a quality welder like an arc welder or GMAW system, along with safety equipment like safety glasses and gloves, plus any necessary PPE depending on your project requirements. Keep your workspace clean throughout the process, and practice good housekeeping techniques for optimal results! With this knowledge about tack welding under your belt, now you’re ready to start tackling projects around the shop! So get out there and start tacking!
