Tips to Control Spot Weld splash:
Vehicle producers utilize spot welding to hold body panels and structural jointly rather than employ other welding techniques. This is due to the smallest sum of cost for every spot weld and small electrode consumption. The spot welder has to be set correctly in order for the spot welds to hold and to decrease the sum of spatter produced during the spot welding process. Spatter created during spot welding is in fact molten metal that is released from the spot weld. The molten metal forms a jagged ring that surrounds the spot weld.
1). Slide the well toothed flat file over the top and bottom copper welding electrodes of the spot welder. The instructions of both electrodes ought to be glossy with no visible tarnish.
2). Put on your protection glasses.
3). Adjust the weld settings on the spot welder for the measure of sheet metal you will be spot welding. This contains the squeeze time, hold time and electrical energy.
4). Turn on the spot welder, overlap the two pieces of sheet metal and depress the pedal of the spot welder to spot weld the two pieces of sheet metal jointly.
5). Twist the spot welded sheet metal 1/4 of an inch and after that release the pedal of the spot welder.
6). Run a gloved hand over the spot weld. If your gloved hand catches to the spot weld, you have splash nearby the weld point and you need to continue to Step 7. If your glove doesn’t catch on the weld, the spot welder is set properly.
7). Augment the weld force and squeeze time of the spot welder. Perform one more test spot weld and do again Step 6 to make sure that there is no splash around the spot weld. Continue adjusting the weld setting listed in this step until your gloved hand doesn’t catch on the spot weld.
8). Clean the copper electrodes following you have the spot welder set correctly previous to you use the spot welder to weld extra sheet metal.
