If you are planning on welding your commercial metal products such as structural building elements or equipment parts, you should think about opting for the spot welding method. In general, spot welding is more favourable over alternative methods because of the lower process costs. Unlike other metal joining methods, the spot welding process joins the pieces of material by welding multiple but separate points instead of a continuous line. Also, this welding method is quite fast. In addition, you can conduct spot welding even if you are not highly experienced. Here are some essential tips to help you ensure that the spot welding work is successful.

Clean the Material

You should clean the surfaces of the materials that you intend to weld together. In simple terms, you should not proceed with the joining work if the metals are covered with rust, dust, old paint or other foreign deposits. These contaminants can compromise the efficiency of the welding process by interfering with the conduction of heat and the softening of the metal. You can wipe, wash or scrub the materials, depending on the level of contamination.

Align the Metals

When spot welding two metal pieces, you should make sure that they are perfectly aligned. There should be no gap between the two metal structures or products for the best results. The presence of space when welding will make complete connection of the two structures impossible. Simply speaking, the welded spots will not be able to keep the pieces together if there is misalignment or gaps. For the best results, you should stabilise the metal products by using clamps.

Choose Ideal Equipment

You should select the best equipment for spot welding, depending on the requirements of the projects. In general, the most important element in the welding setup is the welding tongs. These components will determine the heat output and the pressure exerted when welding. If you would like more heat or a higher amperage output, you should opt for shorter tongs because of the shorter conduction length. If you would like more heat control when welding, you can choose longer tongs. However, you should remember that longer tongs are lighter. The pressure exerted will be lower.

Spot welding is not complicated, but poor handling of the equipment and materials can cause unnecessary problems. In addition, there are significant risks of injury when working with welding equipment. Therefore, if you are interested in conducting a metal joining process, you should hire an experienced fabricator for assistance.
