By James Paul

Tack welding is employed across the welding and fabrication industry. Even the most simple of welding roles at home will need you to do tack welds. This is one of the mig welding basics that you will need to learn. It is more often than not the foundation for of any weldomng you do.

Fabrication and welding strategies call for the requirement of tack welding. Made weldments and elements need tack welding to hold assemblies and parts together during primary fit up and measuring. These welds are used to hold things square, they will oftern be removed once the full welds have been put in place.

An example of a tack weld would be if you were making a gate out some steel box section. The tack weld would hold the steel box section in place as needed, meaning that you will be able to create the gate in less time.

An example of a tack weld would be if you were making a gate out some steel box section. Step 1 would be to chop the steel to the necessary lengths. Then you would lay the 4 lengths of steel on your workbench or onto the floor. You would then employ a square to align the steel into a rectangle and clamp them together.

The tack welds are placed on all 4 corners so that it is held true and square. These little tack welds will when you full weld the steel together, forestall the steel frame from twisting and bend out of square a load more than if you simply started fully welding it all up. Also tack welds are tiny so that if you are making a mistake you cut and square things up again, it is better to grind away a tiny tack weld versus a big full weld. When you know the tack weld there are numerous other mig welding basics that you can do. - 21396
